Agilent Technologies: Ethanol Impurity Analysis Using the </strong><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=10&amp;search=Cary+3500"><strong>Agilent Cary 3500 Flexible UV-Vis Spectrophotometer</strong></a></h3><p><strong>The use of long-path-length cells in pharmaceutical QC</strong></p><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_ethanol_impurity_analysis_cary_3500_flexible_uv_vis_5994_9041en_agilent_3980fa0dc8.pdf"><strong>Full PDF for download</strong></a></li></ul><p>Ultraviolet-visible (UV-Vis) spectroscopy is a rapid, sensitive, and nondestructive test widely used in the pharmaceutical industry for quality control (QC). This method typically involves using a standard 10 mm path length cuvette to measure absorbance of materials, which can then be used in QC labs to quantify or qualify an analyte of interest.&nbsp;</p><p>In UV-Vis measurements, the photometric response of the spectrophotometer follows the Beer‑Lambert law, where a linear relationship exists between the sample absorbance and sample path length. The path length is the distance that the incident light travels through a sample. Increasing the cuvette path length from 10 to 50 mm increases the absorbance of a sample, aiding in more accurate quantification of components with low peak intensity. Alternatively, if the sample concentration is high and exceeds the linear dynamic detection range of the system, a cuvette with a shorter path length can be used instead.<sup>1</sup></p><p>In the pharmaceutical industry, ethanol is widely used in manufacturing as a disinfectant, solvent, and preservative. Due to its amphipathic structure, ethanol can dissolve both hydrophilic and lipophilic substances, serving as a medium to dissolve key components for a broad spectrum of drug formulations. The dual nature of ethanol also allows it to inhibit microbial growth by disrupting cellular membranes and denaturing proteins, processes that are vital for disinfection and the preservation of&nbsp;medications.<sup>2</sup>&nbsp;</p><p>As a result, ethanol used in pharmaceutical manufacturing must comply with pharmacopeia standards to ensure drug safety, efficacy, and quality. The United States Pharmacopeia (USP)<sup>3</sup>, European Pharmacopoeia (EP)<sup>4</sup>, and Japanese Pharmacopoeia (JP)<sup>5</sup> all specify using an ultraviolet absorption test to measure impurities in ethanol at designated wavelengths (Table 1). In this test, the absorption spectrum should show a steadily descending curve with no observable peaks or shoulders, which serve as qualitative indicators of impurities present in the sample. Since the impurities have low absorbance levels, the USP, EP, and JP require the use of a 50 mm cell to improve sensitivity and detection levels.</p><h4><strong>Conclusion&nbsp;</strong></h4><p>The <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=10&amp;search=Cary+3500"><strong>Agilent Cary 3500 Flexible UV-Vis spectrophotometer</strong></a> with variable-path-length cell holder demonstrates exceptional performance in the measurement of ethanol impurities according to global pharmacopeia standards. This underscores the system's suitability for pharmaceutical‑grade quality control. Combined with Agilent Cary UV Workstation software and a 10-year xenon flash lamp replacement warranty, this system delivers a user-friendly interface and global pharmacopeia-compliant hardware (USP, EP, JP), providing long‑term stability and low maintenance. Optimized workflows enable precise, routine photometric quality checks to ensure products are in compliance with pharmaceutical-grade standards.</p><h3><strong>2. LECO: Determination of Nitrogen/Protein in Whey and Powdered Dairy Products</strong></h3><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/FP_928_NITROGEN_PROTEIN_WHEY_POWDERED_DAIRY_203_821_671_1ecb5b0d95.pdf"><strong>Full PDF for download</strong></a></li></ul><p>Two of the main types of proteins in milk are casein and whey. Whey protein is a co-product of cheese production and represents the water-soluble protein remaining in the solution after the milk has been acidified or a coagulation agent has been added. The removal of the non-soluble casein protein portion is referred to as curds. Whey protein is a common ingredient in many dietary supplements due to its availability, solubility, and unique functional characteristics.&nbsp;</p><p>The accurate and precise determination of protein in whey and powdered dairy products not only plays a role in the characterization of nutritional or dietary value in dairy products, but may also be key in determining the quality or category of the dairy product. Protein in whey and other dairy products is most commonly calculated using the measured Nitrogen in the sample and a protein factor multiplier (protein factors vary according to the sample matrix).</p><h4><strong>Instrument Model and Configuration&nbsp;</strong></h4><p>The <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/products/1885"><strong>LECO FP928</strong></a> is a macro combustion Nitrogen/Protein determinator that utilizes a pure Oxygen environment in a high-temperature horizontal ceramic combustion furnace, utilizing ceramic boats designed to handle macro sample masses (~ 1.0 g). A thermoelectric cooler removes moisture from the combustion gases before they are collected in a ballast. The gases equilibrate and mix in the ballast before a representative aliquot (3 cm<sup>3</sup> or 10 cm<sup>3</sup> volume) of the gas is extracted and introduced into a flowing stream of inert carrier gas (Helium or Argon) for analysis. The aliquot of gas is carried through a heated reduction tube, filled with Copper, to convert Nitrogen Oxide combustion gas species (NO<sub>x</sub>) to Nitrogen (N<sub>2</sub>). The aliquot gas is then carried to a thermal conductivity cell (TC) for the detection of Nitrogen (N<sub>2</sub>).&nbsp;</p><p>Thermal conductivity detectors work by detecting changes in the thermal conductivity of the analyte gas compared to a reference/carrier gas. The greater the difference between the thermal conductivity of the carrier gas and the analyte gas, the greater the sensitivity of the detector. The FP928 supports either the use of Helium or Argon as the instrument's carrier gas. When used as a carrier gas, Helium provides the highest sensitivity, and the best performance at the lower limit of the Nitrogen range. The thermal conductivity difference between Argon and Nitrogen is not as great as the thermal conductivity difference between Helium and Nitrogen; therefore, the detector is inherently less sensitive when using Argon as a carrier gas.</p><h4><strong>TYPICAL RESULTS&nbsp;</strong></h4><p>Data was generated utilizing a linear, force through origin calibration using ~0.75 g of LECO 502-896 (Lot 1007) LCRM EDTA (9.59% N). The calibration was verified using ~0.1 g of LECO 502-688 (Lot 1004) LCRM Nicotinic Acid (11.37% N). Samples were weighed and analyzed at ~0.5 grams. A protein † factor of 6.38 was used for all samples to calculate the protein content.</p><h3><strong>3. Shimadzu: High-Temperature Gigacycle Fatigue Test of Inconel 718 and Element Distribution Measurement on a Fracture Surface</strong></h3><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_01_01082_en_37d9ba3a1a.pdf"><strong>Full PDF for download</strong></a></li></ul><h4><strong>User Benefits</strong></h4><ul><li>Fatigue testing at 20 kHz can be performed using an ultrasonic fatigue testing machine, and 109 cycle fatigue tests can be completed in about 14 hours.</li><li>High-temperature fatigue tests can be performed by using a combination of an ultrasonic fatigue testing system and an induction heating furnace.</li><li>The origins of fatigue fractures and inclusions can be identified by observations and element distribution measurements using an electron probe microanalyzer.</li></ul><p>Inconel 718 has excellent heat and corrosion resistance and high strength. Its mechanical properties can be maintained even under high-temperature environments, which is why it is used in harsh environments, such as in the jet engines and turbine blades in the aerospace industry, and in gas turbines and nuclear power plant parts in the energy industry. In these applications, long-term reliability is crucial, making fatigue testing essential. However, this can be time-consuming; for example, gigacycle fatigue testing exceeding 109 cycles takes three to four months at a frequency of 100 Hz when using a conventional fatigue testing machine. But with the USF-2000A ultrasonic fatigue testing system, tests performed at a frequency of 20 kHz can be completed in approximately 14 hours.&nbsp;</p><p>This article describes using the <strong>USF-2000A</strong> to perform gigacycle fatigue tests on Inconel 718 at 600 °C. In addition, the EPMA8050G, which is an electron probe microanalyzer (EPMA ), was used to observe the fatigue fracture surfaces and measure the element distribution.</p><h4><strong>Conclusion&nbsp;</strong></h4><p>Gigacycle fatigue tests were performed on Inconel 718 at 600 °C, using the USF-2000A ultrasonic fatigue testing system. Good results were obtained since the number of cycles to fractures fell in the range 106 to 109 for their respective loading conditions. The EPMA-8050G electron probe microanalyzer was used to perform elemental mapping analysis of fractures originating from inclusions, and the elements of the inclusions were identified.</p><h3><strong>4. Thermo Fisher Scientific: XPS depth profiling of coated nitrided steel using femtosecond laser ablation</strong></h3><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/xps_depth_profiling_coated_nitrided_steel_appnote_d19841e6c9.pdf"><strong>Full PDF for download</strong></a></li></ul><p>X-ray photoelectron spectroscopy (XPS) is a powerful surface analysis technique that provides essential information about elemental composition along with chemical and electronic states. Depth profiling, a process in which material is repeatedly and sequentially analyzed with XPS and removed, provides access to buried features, layers, and interfaces. Traditional ion sputtering methods for depth profiling can, however, lead to preferential sputtering and chemical damage, impacting the reliability and accuracy of results. This is particularly problematic for complex, multi-layered structures and coatings, where it is crucial for the stoichiometry and chemical integrity to be maintained throughout the depth profile.&nbsp;</p><p>This application note explores the use of femtosecond laser ablation (fs-LA) as an alternative to conventional ion sputtering for XPS depth profiling. Specifically, this approach is used to analyze a nitrided steel surface coated with a titanium-doped molybdenum disulfide (MoS₂:Ti) layer, which was applied with physical vapor deposition (PVD). Nitriding is typically used in applications where durability is critical, such as in the production of gears, as it increases surface hardness and wear resistance. The addition of a MoS₂:Ti coating offers additional benefits such as enhanced lubrication and wear resistance. Molybdenum disulfide is well-known for its lubricating properties, and doping with titanium improves mechanical strength and adhesion to the substrate. Accurate depth profiling is essential for unraveling how these structures increase performance and for their further optimization and improvement.</p><h4><strong>Experimental</strong></h4><p>A <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/products/2206"><strong>Thermo Scientific™ Hypulse™ Surface Analysis System,</strong></a> equipped with both traditional ion sputtering and fs-LA capabilities, was utilized for the analysis. XPS data was collected in SnapShot mode using a 30 µm X-ray spot size. A 500 eV monoatomic Ar⁺ beam from a Thermo Scientific™ MAGCIS™ Dual Beam Ion Source was used for sputter depth profiling. The fs-LA depth profiles were generated using a 1,030-nm laser operating at a 160 fs pulse length. The pulse energy was increased from 83 µJ to 250 µJ when transitioning from the MoS₂:Ti coating into the bulk steel material.</p><h4><strong>Summary&nbsp;</strong></h4><p>XPS depth profiling with femtosecond laser ablation offers a robust alternative to traditional ion sputtering, particularly for materials sensitive to preferential sputtering and chemical damage. The technique provides accurate stoichiometric analysis and preserves chemical state information, making it ideal for complex, multi-layered structures with deeply buried interfaces. The fs-LA method can offer comparable depth resolution to ion sputtering while being able to profile greater depths in a fraction of the time.&nbsp;</p><p>This application note demonstrates the effectiveness of fs-LA in maintaining the chemical integrity of a nitrided steel material with a MoS₂:Ti coating throughout a depth profile, providing accurate and reliable results in a practical timeframe.</p>

KNAUER: Analysis of HPLC fractions by Benchtop NMR</strong></h3><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/knauer_hplc_benchtop_nmr_web_638c60e13c.pdf"><strong>Full PDF for download</strong></a></li></ul><p>Preparative HPLC is essential for isolating compounds and removing impurities in pharmaceutical and chemical industries. Non-destructive, fast analysis is preferred to maintain yield and enable at-line monitoring, avoiding lengthy sample preparation. Recent advancements in benchtop NMR spectrometers (up to 90 MHz) allow quick analysis without deuterated solvents. In this proof-of-concept study we purified a pharmaceutical sample via HPLC and confirmed its identity using benchtop NMR. Fractions (0.7–4.4 mM) were analyzed without preparation, using only 300 µL per sample, ensuring rapid batch control with no product loss. This study demonstrates the seamless integration of HPLC and benchtop NMR.</p><h4><strong>Experimental</strong></h4><h5><strong>Preparative HPLC Method</strong></h5><p>Eluent 20:80 Ethanol/water, isocratic mode, flow rate 12.5 ml/min, detection UV254 nm 2 Hz, 500 µl stacked injection, automated fractionation with threshold function, column temperature ambient, Column Eurospher II 100-10 C18 150x20 mm&nbsp;</p><h5><strong>Analytical HPLC Method</strong></h5><p>Eluent 20:80 Ethanol /water + 0.1% formic acid, isocratic mode, flow rate 1 ml/min, detection UV254 nm 10 Hz, 5 µl partial loop injection, column temperature 25 °C, Column <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/products/1633"><strong>Eurospher II 100-5 C18</strong></a> 150x4 mm&nbsp;</p><h5><strong>NMR Method&nbsp;</strong></h5><p>NMR spectra were acquired on a <strong>Magritek Multi-X Ultra 80 MHz benchtop NMR system</strong> using an adapted WET sequence for solvent suppression. 32 scans were acquired with a repetition time of 15s. WET parameters were adjusted for each sample to yield optimal suppression for all solvent signals. Pooled HPLC fractions were analysed directly without addition of deuterated solvents or other sample preparation.</p><h4><strong>Conclusion</strong></h4><p>This proof-of-concept study successfully shows that HPLC and benchtop NMR can be used together easily. Samples can be analyzed non-destructively within minutes and without any further preparation due to highly efficient suppression of multiple solvent signals. Compounds can be identified without the need of reference standards. This study shows that NMR can provide a valid compatible alternative detector for HPLC fraction analysis.</p><h3><strong>2. Shimadzu: DIC Analysis in High-Speed Tensile Test of CFRP</strong></h3><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_01_00854_en_fb6c68b858.pdf"><strong>Full PDF for download</strong></a></li></ul><h4><strong>User Benefits</strong></h4><ul><li>The <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=1&amp;search=HPV-X3"><strong>HPV-X3</strong></a> is suitable for observation of fracture of brittle materials such as CFRP because it has a maximum recording speed (framerate) of 20 Mfps.&nbsp;</li><li>The HPV-X3 provides improved DIC analysis performance, as its resolution is 3 times higher than that of the conventional highspeed video camera.</li><li>The HITS-TX impact testing machine enables testing at a maximum speed of 20 m/s</li></ul><p>Carbon fiber reinforced plastic (CFRP) is a material with particularly high specific strength, even among composite materials, and used in various applications such as transport aircraft, taking advantage of its excellent mechanical properties. Because CFRP consists of carbon fibers and resin, it shows complex fracture behavior, and brittle fracture progresses from damage as the point of origin. Since fracture proceeds instantaneously, a high-speed video camera with a high recording speed is necessary when observing fracture of CFRP. One method for measuring strain in a high-speed tensile test is Digital Image Correlation (DIC), which visualizes the distribution of strain at the specimen surface by comparing a random pattern on the specimen surface before and after deformation. Thus, a high-speed video camera with a high resolution is also necessary in order to improve the DIC performance.&nbsp;</p><p>Newly-developed <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=1&amp;search=HPV-X3"><strong>Hyper Vision HPV-X3 high-speed video camera</strong></a> is extremely well-suited to DIC analysis of CFRP, as its recording speed is 2 timesfaster and itsresolution is 3 times higher than the conventional HPV-X2. In this experiment, a high-speed tensile test of CFRP was conducted using a HITS-TX high-speed tensile testing machine. The condition of the test was observed with the new HPV-X3, and the strain distribution of the CFRP test piece was clarified by a DIC analysis of the recorded images.</p><h4><strong>Test Piece and Test Instruments</strong></h4><p>A CFRP quasi-isotropic laminate was used as the test piece. Aluminum foil was glued to the back side of the test piece, and the timing when the electrical conduction of the aluminum foil was interrupted by fracture of the test piece was used as the trigger for video recording. The HITS-TX was used in the highspeed tensile test. The HPV-X3 was used in fracture observation, and for comparison, the fracture process was also recorded with the conventional HPV-X2 camera. Fig. 1 shows the condition of the test, and Table 1 and Table 2 show the equipment composition and test conditions, respectively.</p><h4><strong>DIC Analysis Results in High-Speed Tensile Test</strong></h4><p>Fig. 3 shows the DIC analysis results in the high-speed tensile test. The color bar was set to display the color purple at around 0 % strain and red at around 2 % strain. Fig. 3 (1) is an image at the start of the test. After the test started, strain in the 45˚ direction concentrated from the lower left to the right central area, as can be seen in Fig. 3 (2). Then, as the test progressed, a condition of increasing strain in the initial area of strain concentration can be seen in Fig. 3 (3) to (9). A crack occurs in Fig. 3 (10), and strain decreases in the crack area. Following this, the test piece fractured completely in Fig. 3 (11) and (12), and a decrease in the strain in the area around the crack could be observed.</p><h4><strong>Conclusion</strong></h4><p>A high-speed tensile test of CFRP was conducted using a HITSTX high-speed tensile testing machine and the newlydeveloped HPV-X3 high-speed video camera, and the strain distribution at the time of test piece fracture was visualized by a DIC analysis. Because the HPV-X3 offers a 3 times higher resolution and a 2 times faster recording speed than the conventional device, it is a suitable high-speed video camera for fracture observation and DIC analysis in impact tests of brittle materials such as CFRP. The measurement system introduced in this Application News article is a useful tool for the development of composite materials.</p><h3><strong>3. Thermo Fisher Scientific: Polymer analysis using femtosecond-laser-ablation depth profiling</strong></h3><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/xps_depth_profiling_polymer_analysis_appnote_c731e2e7e0.pdf"><strong>Full PDF for download</strong></a></li></ul><p>X-ray photoelectron spectroscopy (XPS) is an essential polymer characterization technique that can identify not just the elemental composition but also the chemical state of polymer samples. This allows the chemical bonding environment to be deduced and, as a result, the polymer species can be identified. This can all be achieved with minimal sample preparation thanks to the built-in charge-compensation systems found in XPS instruments, which simplify the analysis of insulating samples.&nbsp;</p><p>The introduction of gas cluster ion sources (GCIS), such as the Thermo Scientific™ MAGCIS Dual Mode Ion Source, marked a major step forward in polymer analysis. Unlike monatomic ion beams, GCIS are able to clean surface contamination, and etch away layers of sample material, without damaging the underlying chemistry of organic samples such as polymers. As a result, GCIS has allowed chemical-damage-free analysis to reach micrometers below the sample surface. This depth of analysis can be highly time consuming, however, and total experimental times can range from multiple hours to days.&nbsp;</p><p>The addition of femtosecond-laser-ablation (fs-LA) technology is alleviating this, allowing for XPS spectra to be collected from a depth of tens of µm into a sample in a matter of minutes. This is because the laser ablation occurs on the femtosecond timescale (i.e., nearly instantaneously), effectively eliminating the material removal time of the depth profile. Additionally, unlike other material removal techniques such as atomic ion beam impact (where a collision cascade effect is induced to remove surface material) fs-LA is capable of removing material without chemical damage due to the ultrashort columbic explosion process used to eject the material. The resulting profile is therefore representative of the actual sample chemistry.</p><h4><strong>Paint layer analysis&nbsp;</strong></h4><p>In traditional ion-beam depth profiling, analytical depths are generally limited to several hundred nanometers, up to a micrometer. This means that it is extremely difficult to analyze the interfaces between multiple micrometer-thick layers in a sample without the use of additional techniques such as ultralow-angle microtome (ULAM) sectioning.¹ The introduction of fs-LA technology, however, allows micrometers of material to be removed rapidly, enabling the characterization of layered samples.&nbsp;</p><p>As an example, a multi-layer paint specimen (provided by the University of Surrey, UK) was depth profiled using the <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/products/2206"><strong>Thermo Scientific™ Hypulse™ Surface Analysis System</strong></a>. The sample consists of an aluminum substrate coated with a 5 µm layer of polyurethane primer followed by a 25 µm PMMA/PVdF topcoat.</p><p>The depth profile was generated using a 1,030 nm laser with an energy of 250 µJ for ablation, along with a 30 µm X-ray spot size for data collection. XPS spectra were collected after each ablation cycle to obtain an atomic concentration plot through both paint layers into the substrate material (Figure 2).&nbsp;</p><p>5 distinct regions throughout the analyzed depth can be seen. The top surface of the sample consists of an adventitious layer of carbon contamination, which is commonly found on samples exposed to air. The second layer is the 25 µm PVdF/PMMA topcoat, and the third layer is the PU primer. Between the primer and the final aluminum substrate layer, a clear increase in adventitious carbon is observed, similar to the signal seen at the top sample surface. This suggests residual carbon contamination was present on the substrate before the paint layers were applied.&nbsp;</p><p>It would take hours to produce the XPS depth profile shown in Figure 2 using traditional ion beam approaches. Even with the use of a monatomic beam with a high energy per atom, the length of the analysis could still be just as long, depending on the sample material, and would sacrifice the chemistry of any organic/polymeric materials. The combination of fs-LA depth profiling and snapshot XPS acquisition, meanwhile, can reduce the experimental time to less than 20 minutes without inducing any chemical damage to the sample surface.</p><h4><strong>Summary&nbsp;</strong></h4><p>One of the most critical aspects of successful polymer XPS depth profiling is the preservation of the sample chemistry during material removal. Additionally, experiment time can be a significant limiting factor, and thicker samples could lead to reduced time for repeat experiments. The femtosecond laser ablation capabilities of the Hypulse Surface Analysis System provide fast, efficient, and chemical-damage-free material removal from a sample surface, enabling analysis multiple micrometers into a sample. This means that hidden sample interfaces, that were largely inaccessible before, can now be analyzed easily and efficiently</p>

MDCW / Mount Royal University: An Analysis of Fresh and Used Aircraft Oil: An Indication of Exposure Pathway Possibility to Inorganic and Organic Pollutants</strong></h3><ul><li>Presentation</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/O_4_Hayes_fed01ca35a.pdf"><strong>Full PDF for download</strong></a></li></ul><p>Aircraft engine oils are highly complex mixtures formulated to meet strict MIL-SPEC requirements for piston, turboprop, and jet engines, often containing proprietary additive packages designed to improve thermal stability, reduce wear, and prevent corrosion. In this presentation at the 17th Multidimensional Chromatography Workshop, Kevin Hayes investigated how aircraft oils change during engine operation and whether these changes could contribute to occupational exposure risks for flight crews and maintenance personnel. The study focused on comparing fresh and used oils from piston, turboprop, and jet aircraft to better understand how inorganic and organic contaminants accumulate or are depleted during normal engine operation.</p><p>The research combined routine multi-element analysis using <strong>ICP-OES</strong> with advanced <strong>GC×GC-TOFMS</strong> speciation analysis. Used piston and turboprop oils were collected with assistance from the MRU Aviation Program, while used jet oil samples were obtained from a private European jet operator. Elemental analysis showed significant differences between new and used oils. In piston engine oils, sulfur and lead concentrations increased substantially during use, with lead accumulation linked to tetraethyl lead (TEL) from 100LL aviation fuel. Phosphorus compounds were also detected in used oils despite not being present in the fresh oil samples, indicating additional contributions from operational processes or additives.</p><p>For jet and turboprop oils, phosphorus-containing additives behaved differently. Fresh oils contained relatively high phosphorus concentrations, but these levels decreased significantly after engine operation, suggesting additive depletion or release of phosphorus-containing compounds during use. The authors highlighted that this may be particularly relevant for bleed-air systems in commercial aircraft, where oil-derived compounds could potentially enter cabin air. GC×GC-TOFMS analysis further identified several organophosphate compounds in piston engine oils. Interestingly, commonly discussed compounds such as tricresyl phosphate (TCP) were not detected, while other organophosphates were observed instead, demonstrating the importance of comprehensive speciation analysis rather than focusing solely on previously suspected contaminants.</p><p>The presentation concluded that aircraft engine oils undergo substantial chemical changes during normal operation, with both inorganic and organic compounds accumulating or being depleted in ways that are not captured by analyses of unused oils alone. While elemental analysis provided valuable first-level insight into wear metals and additive behavior, GC×GC-TOFMS delivered critical molecular-level information about specific contaminant classes and transformation products. Together, the results suggest that current hazard assessments based only on fresh oils may underestimate potential occupational exposure risks and demonstrate the value of combining elemental analysis with advanced multidimensional chromatography for a more complete understanding of aircraft oil-related exposure pathways.</p><h3><strong>2. Shimadzu: Measurement of TOC in Chloroisocyanuric Acid Used as Disinfectant</strong></h3><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_01_01019_en_4c48146421.pdf"><strong>Full PDF for download</strong></a></li></ul><h4><strong>User Benefits</strong></h4><ul><li>Samples such as chloroisocyanuric acid, which are difficult to detect using a wet oxidation TOC analyzer, can be measured with high sensitivity using the combustion oxidation <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=1&amp;search=TOC-L"><strong>TOC-L,</strong></a> which has a strong oxidizing power.</li><li>One sample can be measured quickly, typically within 10-20 minutes.</li></ul><p>In facilities where people have direct contact with water, such as swimming pools, hot springs, and bathhouses, strict water quality management is essential to protect public health and safety. Total organic carbon (TOC) measurement is widely used to detect water quality degradation caused by microbial growth and contamination with foreign substances.&nbsp;</p><p>Solid powder chloroisocyanuric acids (including dichloroisocyanuric acid and trichloroisocyanuric acid), which exhibit minimal chlorine deactivation, are commonly used as disinfectants for swimming pool water instead of sodium hypochlorite solutions. However, because chlorinated isocyanuric acid is a recalcitrant substance, it is challenging to detect using wet oxidation TOC analyzers due to itsresistance to oxidation and decomposition. In contrast, a combustion oxidation TOC analyzer can measure chloroisocyanuric acids with high sensitivity and recovery rates due to itsstrong oxidizing power. In this application, we compared the TOC measurement results for sodium dichloroisocyanurate using a combustion oxidation <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=1&amp;search=TOC-LCPH"><strong>TOC-L<sub>CPH</sub></strong></a> analyzer and a wet oxidation <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=1&amp;search=TOC-VWP"><strong>TOC-V<sub>WP</sub></strong></a> analyzer.</p><h4><strong>Conclusion</strong></h4><p>The combustion oxidation TOC analyzer demonstrated high accuracy in measuring the samples.

X-ray photoelectron spectroscopy (XPS) is an established technique for the characterization of material surface chemistry, capable of revealing compositional information several nanometers into a sample. Depth profiling is a method that extends the analysis range of XPS; by alternating material removal and XPS analysis, it can reveal how composition changes from the surface to the bulk, or across interfaces between different compounds in a sample. This information can be just as critical as how a material’s surface interacts with its environment, and can provide a more complete picture of the material’s behavior and properties.&nbsp;</p><p>The <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/products/2206"><strong>Thermo Scientific™ Hypulse™ Surface Analysis System</strong></a> is a fully featured XPS instrument with a range of additional analytical capabilities, including reflected electron energy loss spectroscopy (REELS) and low-energy ion scattering spectroscopy (ISS). The system is equipped with a Thermo Scientific MAGCIS Dual-Mode Ion Source and a novel femtosecond laser-ablation system (fs-LA) for XPS depth profiling.&nbsp;</p><p>This eBook explores XPS depth profiling in detail and shows how the Hypulse System is ideally suited for this technique, helping you uncover critical surface and sub-surface information.</p>

Shimadzu: Discriminating between Microsamples of Similar Resins with a Combination of FTIR and Thermal Analysis Instruments</strong></h3><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_01_01114_en_a9291de45e.pdf"><strong>Full PDF for download</strong></a></li></ul><h4><strong>User Benefits</strong></h4><ul><li>Using the ATR method with FTIR spectroscopy enables simple and rapid qualitative analysis of polymers.</li><li>DSC analysis may be able to reveal differences in polymer thermal histories that cannot be confirmed by FTIR alone.</li><li>TG-DTA can be used to confirm the content level of inorganic additives in polymers</li></ul><p>A wide range of polymer resins is used in modern society for diverse applications, resulting in increasing demand for qualitative analysis of resin microsamples, such as identifying resin contaminants in products or qualitatively evaluating microplastics for environmental impact assessments. FTIR spectrophotometers are commonly used for qualitative analysis of polymers. In particular, the ATR (attenuated total reflectance) method is widely used because measurements can be performed simply and quickly by clamping a sample against a prism to ensure close contact.&nbsp;</p><p>While the ATR method makes it relatively easy to discriminate between different types of polymers, clear differences may not appear when analyzing similar polymers—for example, when there are only slight differences in the type or content of additives or the thermal histories during manufacturing. In such cases, differences may be confirmed by using thermal analysis instruments, such as a DSC or TG-DTA system.&nbsp;</p><p>This article describes an example in which three instruments— an <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=1&amp;search=IRSpirit-TX"><strong>IRSpirit-TX</strong></a> FTIR spectrophotometer, a <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=1&amp;search=DSC-60+Plus"><strong>DSC-60 Plus</strong></a> differential scanning calorimeter, and a DTG-60 simultaneous DTA-TG unit (Fig. 1)—were used to confirm differences among six microsamples of polypropylene (PP) resin.</p><h4><strong>Conclusion</strong></h4><p>Details of the six types of PP resin identified from the above measurement results are shown in Table 4. The results indicate that by using an FTIR spectrophotometer in combination with thermal analysis equipment, such as DSC and TG-DTA systems, it is possible to distinguish between minute amounts of the same type of resin with various different properties.</p><h3><strong>3. Thermo Fisher Scientific: XPS depth profiling of advanced solar cells with femtosecond laser ablation</strong></h3><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/xps_depth_profiling_advanced_solar_cells_appnote_7bda4471a5.pdf"><strong>Full PDF for download</strong></a></li></ul><p>Perovskites are an emerging class of materials in the solar cell industry, exhibiting a number of promising properties, such as improved efficiency and weight, compared to traditional silicon-based devices. X-ray photoelectron spectroscopy (XPS) is an established tool in solar cell research due to its ability to provide extremely surface-sensitive information about elemental composition along with chemical and electronic states.¹ XPS is ultimately a surface analysis technique, however, and in order to assess the full composition of complex, multi-layered structures such as solar cells, a technique known as depth profiling is necessary, which performs multiple rounds of successive material removal and analysis.&nbsp;</p><p>This application note explores a recent study by Chandler et al. that focuses on solar cells designed for aerospace applications,² where accurate determination of the “true” starting composition of the stacks is essential for tests that simulate space conditions, such as radiation exposure. Without a reliable baseline, it becomes impossible to distinguish between changes induced by the experimental conditions and artifacts introduced during analysis. Conventional ion beam sputtering methods used for depth profiling are known to distort chemical information for perovskites; femtosecond laser ablation (fs-LA) is presented as a novel, alternative method that helps to preserve vital chemical information.</p><h4><strong>Experimental</strong></h4><p>A halide-perovskite-based solar cell was fabricated on an ITO/SnO₂ substrate using a spin coating method; the structure of the layers is shown in Figure 1.</p><p>Analysis was performed with the <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/products/2206"><strong>Thermo Scientific™ Hypulse™ Surface Analysis System</strong></a>, which is equipped with both traditional ion-beam sputtering and femtosecond-laser ablation capabilities. XPS data was collected in SnapShot acquisition mode using an X-ray spot size of 30-200 µm, depending on the method of depth profiling.&nbsp;</p><p>A MAGCIS ion gun was employed for the sputter depth profiles, generating either a 500 eV monatomic Ar⁺ beam or 8 keV Ar₁₅₀⁺ clusters. The fs-LA depth profiles were generated using a 1,030 nm wavelength laser operating at a 160 fs pulse length. The pulse energy was increased from 42 µJ to 167 µJ when transitioning from the perovskite layer into the substrate structure. A flood gun was employed for charge neutralization during profiling.</p><h4><strong>Summary&nbsp;</strong></h4><p>This study confirms the challenges associated with traditional ion sputtering (both monatomic and cluster) for the depth profiling of perovskite-based solar cells. These methods cause preferential sputtering, particularly of lighter elements like carbon, nitrogen, and iodine, which distorts elemental ratios in the profiles and results in artificial signals, such as the formation of metallic lead (Pb⁰). Depth profiling with femtosecond laser ablation represents a novel and robust alternative that preserves the original chemical composition and oxidation states throughout the perovskite layer. By avoiding preferential removal effects, accurate compositional information is maintained during the profile, and erroneous peak signals associated with chemical reduction are eliminated. These factors are vital in establishing a chemically undisturbed baseline before performing tests that simulate environmental effects on the solar cells.&nbsp;</p><p>With fs-LA depth profiling, any induced changes can be confidently delineated from analytical artifacts, and researchers can better understand and mitigate environmental effects on solar-cell performance, eventually leading to improved solar technologies for aerospace applications.</p>

ICP-MS systems with integrated CRCs range from single quadrupole (SQ) ICP-MS used in environmental and food analysis, to triple quadrupole ICP-MS (ICP-QQQ) for advanced research applications. For routine applications, Helium Kinetic Energy Discrimination (He KED) mode, commonly referred to as helium mode (He mode), is the most widely used CRC operational mode. The widespread use of He mode is due to its universal effectiveness in reducing a broad range of polyatomic interferences without the need for element-specific optimization.&nbsp;</p><p>Unlike CRCs that rely on reactive cell gases and require complex tuning (often referred to as reaction cells), He mode effectively mitigates many commonly occurring polyatomic ion interferences without the need for intricate adjustments. In contrast, reaction cells often require careful selection of gas type (such as ammonia or oxygen) and tuning parameters based on the specific interfering ions on analytes of interest.&nbsp;</p><p>Building on the simplicity of He mode, Agilent has developed Advanced Helium Mode (AHM) for the <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=10&amp;search=9500"><strong>Agilent 9500 Triple Quadrupole ICP-MS (ICP-QQQ)</strong></a>. AHM represents a breakthrough in interference removal technology, enabled by the newly designed Agilent Dual-Cell System (DCS) and high-speed cell voltage control. These innovations deliver high sensitivity across the mass range and superior interference removal performance for routine applications. Compared to conventional He mode, AHM demonstrates the following improvements:</p><ul><li>Around a 20-fold sensitivity improvement for low-mass elements, such as beryllium (Be) and boron (B)&nbsp;</li><li>Around a 2-fold improvement for mid-to-high mass elements&nbsp;</li><li>A reduction of more than 33% in data acquisition time while maintaining detection limits (DLs), accelerating analytical measurement times&nbsp;</li></ul><p>AHM not only replaces traditional He KED but also consolidates multiple tuning modes including no gas, He, and HEHe into a single, streamlined mode. Integrated into the 9500 ICP-QQQ, AHM is a next-generation standard He mode that is faster, simpler, and delivers higher performance than its predecessor. This technical note describes the performance enhancement mechanisms of the DCS and AHM. It also includes some comparative results with conventional He KED mode to highlight the analytical improvements of AHM.</p><h4><strong>Overview and advantages of AHM&nbsp;</strong></h4><p>Typically, multi-element ICP-MS methods apply no gas mode to the determination of low-mass elements like Be and B due to low sensitivity in traditional He KED mode. Consequently, many routine ICP-MS applications have required multiple tune setups, combining no gas, He, and HEHe. Each mode switch introduces a delay due to cell pressure stabilization requirements.&nbsp;</p><p>In practice, low-mass elements (m/z &lt; 23) are generally unaffected by polyatomic ion interferences, so KED is often unnecessary. Therefore, in AHM, different voltages are applied to the DCS (effectively disabling KED) for low-mass elements, while keeping standard settings for elements with m/z ≥ 23.&nbsp;</p><p>The DCS voltages are dynamically switched in sync with Q2 using a high-speed voltage control circuit, providing over 20× sensitivity improvement for low-mass elements compared to conventional He mode. AHM eliminates the need to run in no gas mode, greatly simplifying the method. As a default approach, AHM alone is suitable for most applications.<sup>1</sup></p><h3><strong>2. Shimadzu: Damping Force Characteristic Test of Suspension Struts [JASO C611]</strong></h3><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_01_01017_en_2fbbb9c247.pdf"><strong>Full PDF for download</strong></a></li></ul><h5><strong>User Benefits</strong></h5><ul><li>Damping force characteristic tests on suspension struts can be performed based on the JASO C611 standard.&nbsp;</li><li>Combination test enables automatic speed change and measurement.&nbsp;</li><li>High responsiveness of the EMT series enables testing at high excitation speed.</li></ul><p>Various components play an important role in achieving a comfortable ride in vehicles. Among them, the suspension strut used in the suspension system is an important component that stabilizes the vehicle body by mitigating the impact caused by uneven road surfaces.&nbsp;</p><p>“JASO C611 Suspension Struts for Automobiles”1), a standard of JASO (Japanese Automotive Standards Organization), established by JSAE, specifies the definition, quality, and test method for suspension struts. There is no international standard that is equivalent to JASO C611.&nbsp;</p><p>In order to improve the performance of suspension struts, it is necessary to measure the damping force against speed by changing the excitation speed. The performance of suspension struts can be confirmed by measuring the response, such as the relationship between speed and damping force and the Lissajous waveform.&nbsp;</p><p>This article introduces an example of the test method “Damping Force Characteristic Test” specified in JASO C611, which was conducted on a Shimadzu EMT series electromagnetic fatigue testing machine.</p><h4><strong>Testing Equipment&nbsp;</strong></h4><p>The EMT-1kNV-50 electromagnetic dynamic and fatigue testing machine was used in this test. Fig. 1 shows a photograph of the testing machine. The electromagnetic actuator with extremely high frequency response enables highly accurate dynamic testing. In this test, the maximum test speed was 0.6 m/s. The EMT seriesis most suitable for testing at such high frequencies.</p><h4><strong>Conclusion&nbsp;</strong></h4><p>A damping force characteristic test on a suspension strut based on JASO C611 was conducted using an EMT series electromagnetic fatigue testing machine and Windows software for 4830. The test conditions were set using the excitation speed, and it was confirmed that the test was accurately controlled as set. The standard “JASO C611 Suspension Struts for Automobiles” referred to this time is derived from “JASO C602 Automotive Parts - Telescopic Shock Absorbers for Suspension Systems”2). Although C602 also prescribes a damping force characteristic test, it is almost equivalent to the C611, and the test machine configuration can be used by replacing the jig.</p><h3><strong>3.
