Agilent Technologies: <style type="text/css"></style><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_v_groove_nebulizer_5994_7788en_agilent_4ae77b4b3a.pdf">Reducing Instrument Downtime in Elemental Analysis of Lubricant Oils as per ASTM 5185</a></h4><ul><li>Application</li></ul><h5>Run samples faster and for longer using the V-groove nebulizer</h5>AbstractIn this application note, lubricant oil samples were analyzed using an Agilent 5900 Synchronous Vertical Dual View (SVDV) inductively coupled plasma optical emission spectrometer (ICP-OES) coupled with an Agilent Advanced Valve System 6 (AVS 6) and the Agilent V-groove nebulizer to enable the rapid analysis of over 1,000 samples in 6 hours (more than 160 samples per hour). The V-groove nebulizer provides exceptional performance characteristics, robustness, and durability, even when using troublesome samples. It also provides a reduction in sample loading on the plasma, which reduces carbon formation on the injector of the torch, allowing extended run times, while exceeding the sensitivity requirements required for the ASTM D5185-18 standard method.IntroductionElemental analysis of lubricant and hydraulic oils is essential for predictive and preventive maintenance, as well as trend analysis in many heavy industries. The ASTM D5185‑18 standard method1 is the gold standard in tribology laboratories globally to quantify additive elements, wear metals, and contaminants. This method uses ICP-OES for the rapid elemental determination of 22 elements in both used and unused lubricating and base oils, providing quick screening of used oils for signs of wear.Tribology laboratories typically process hundreds of samples daily; therefore, they are constantly searching for ways to enhance efficiency and improve sample throughput. Instrument downtime caused by blockages in the sample introduction system (SIS) can be a common problem in these high-throughput labs. These blockages are typically caused by suspended particles in the samples blocking the nebulizer, and carbon deposits blocking the injector of the torch. Although various methods exist to remove the blockage from the nebulizer and clean the torch, all require extinguishing the plasma to remove and clean the SIS.The use of a robust nebulizer is a strategy that can enable tribology laboratories to run more samples with reduced blockage. This will improve their workflows and increase sample throughput, reducing both instrument downtime and their running costs. One example of a robust nebulizer that helps to overcome the blockage issues is the inert, high-total-dissolved-solids (high-TDS) Agilent V-groove nebulizer, which is capable of aspirating highly dissolved solids and slurries (up to 30% dissolved solids with a maximum particle size of 350 μm). Its inert construction also ensures that any solvent can be nebulized.In this application note, used diesel engine lubricant oil samples were analyzed using the 5900 SVDV ICP-OES coupled with the AVS 6 and the V-groove nebulizer, following the ASTM D5185-18 standard method.&nbsp;ConclusionThis application note shows the suitability of the Agilent 5900 SVDV ICP-OES used with the Agilent AVS 6 and inert V-groove nebulizer for rapid multi-element analysis of used lubricant oil samples using the ASTM D5185-18 standard method.Excellent long-term stability was demonstrated when more than 1,000 samples were analyzed over a six-hour period (22 to 23 seconds per sample). All measurements of this spiked oil sample were within ± 10% of the expected value, with precision better than 5% RSD in most cases. The spike recovery study showed how the 5900 ICP-OES, used with the inert V-groove nebulizer, can accurately detect low range concentrations of wear metals and high concentrations of the elements from the additive package in a single analysis. The inert V-groove nebulizer also enabled the samples to be run faster, with excellent accuracy.Despite no oxygen injection being used, there were no signs of blockage of the injector of the torch, or carbon deposition after the test. The V-groove nebulizer design reduces sample loading on the plasma, minimizing carbon buildup while maintaining the sensitivity required for the ASTM D5185 standard method. No nebulizer blockage was experienced while collecting the data for this study. The inert V-groove nebulizer allows extended run times by reducing the frequency of torch and nebulizer maintenance. This demonstrates the stability of the 5900 ICP-OES and the suitability of the inert V-groove nebulizer for high-throughput tribology laboratories, by reducing instrument maintenance downtime and improving sample throughput.<h4>2.

Halogen analysis is commonly carried out using ion chromatography (IC), whereas argon plasma-based techniques like ICP-MS are less common, due to poor sensitivitiy, and potential spectral interferences. This study describes a complete analytical workflow using the Thermo Scientific™ iCAP™ TQe ICP-MS for the accurate and precise quantification of challenging halogen analytes like fluorine, chlorine, and bromine.CONCLUSIONSThis work highlights how triple quadrupole ICP-MS systems, such as the iCAP TQe ICP-MS, operated in TQ-O 2 mode can be used for accurate and precise quantification of challenging analytes such as halogens.<ul><li>It could be shown that chlorine and bromine can be analyzed directly using optimized instrument conditions.</li><li>It further highlights the feasibility of iCAP TQe ICP-MS for indirect but accurate and precise determination of fluorine by following approach of complex formation with barium under optimized and controlled conditions</li><li>The analytical data and observations made during this study strongly suggest that iCAP TQe ICP-MS equipped with dedicated mass flow controllers (MFCs) for introduction of pure oxygen and pure helium as cell gases is a powerful tool to accomplish the otherwise challenging analysis of halogens.</li><li>Upcoming studies will focus on the application of the fluorine measurements in hyphenated techniques, such as liquid chromatography hyphenated to ICP-MS to assess the potential for emerging contaminant screening, i.e. of PFAS</li></ul><h4>3.

One of the components of LIBs, the anode, accumulates and releases Li ions during charging and discharging. Graphite-based materials are mainly used as the anode material in LIBs. In China, one of the major producers, the analysis of elemental impurities in graphite, which is used as LIB anode material, is required by GB/T 24533-20191) using inductively coupled plasma atomic emission spectroscopy (ICP-AES).In this Application News, elemental impurities in LIB anode materials were analyzed using the ICPE-9820. Spike recovery tests were performed to confirm the validity of the analytical values. Additionally, the “Acquisition for All Wavelength” feature allows for checking the presence of elemental impurities that were not subjected to quantitative analysis.ConclusionIn this Application News, an analysis of elemental impurities in LIB anode materials was performed using the ICPE-9820. Good spike recoveries were obtained, confirming the accuracy of the analysis. Additionally, elements and wavelengths were added after the measurement to identify elemental impurities other than the analyzed elements present in the anode materials.<h4>4. Metrohm: <style type="text/css"></style><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_pan_1064_download_39b556efd8.pdf">Monitoring complexing agents in galvanic baths inline with Raman spectroscopy</a></h4><ul><li>Application</li></ul>The main purposes of galvanic process baths include the surface refinement of workpieces and the setting of physical properties. To this end, bath additives (e.g., organic compounds or complexing agents) are regularly added in different amounts, depending on the processing load. Since the bath composition changes continuously due to the introduction of the workpieces, close monitoring of the concentration of the bath additives is necessary to ensure that the end product quality is at the highest level.This Process Application Note presents a method to accurately analyze complexing agents inline in galvanic baths with a 2060 Raman Analyzer from Metrohm Process Analytics. This enables real-time bath control and thus an increase in production efficiency and product quality.CONCLUSIONRaman spectroscopy is an easy-to-use analytical technique that identifies liquids and solids within seconds. The 2060 Raman Analyzer from Metrohm Process Analytics is a high-performance Raman system designed for monitoring different processes like electroplating.Together with Metrohm’s Vision and IMPACT software, the 2060 Raman Analyzer can be used to acquire real-time results, increase roductivity, and lower production costs.

News from LabRulezICPMS Library - Week 40, 2024

<h4>The Science</h4>Nuclear magnetic resonance (NMR) spectroscopy is used to detect and identify the structure of molecules, and it has become increasingly important in environmental science. The data produced from NMR analyses need a lot of additional processing to be useful. This makes it difficult for nonexperts to use and apply this technique. We introduce a new R package, called nmrrr, to process and visualize NMR data. This open-source package can be integrated into existing NMR processing workflows. The package can be used to process spectra and peak data, calculate relative abundances, and plot graphs of spectra. The nmrrr package is currently available on two platforms: CRAN and GitHub.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Pacific_Northwest_National_Laboratory_Kaizad_F_Patel_New_Soft_An_R_Package_for_NMR_Data_Processing_The_nmrrr_package_can_be_used_to_process_spectra_from_solution_and_solid_state_13f448377b.jpg" alt="Pacific Northwest National Laboratory / Kaizad F. Patel: The nmrrr package can be used to process spectra from solution- and solid-state." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Pacific_Northwest_National_Laboratory_Kaizad_F_Patel_New_Soft_An_R_Package_for_NMR_Data_Processing_The_nmrrr_package_can_be_used_to_process_spectra_from_solution_and_solid_state_13f448377b.jpg 208w," sizes="100vw" width="1600" height="1200"><h4>The Impact</h4>Despite advances in NMR analyses, manual integration and data processing are still the norm for environmental sample workflows. The nmrrr package is intended for processing NMR data, including cleaning data from multiple files, visualizing NMR spectra, performing binning/integrations for functional groups, and calculating relative abundances. A major feature of this package is its ability to batch-process multiple samples in a reproducible manner. This package is designed for use in the R language for statistical computing, and it can be easily inserted into analysis workflows to help analyze and interpret NMR data. The nmrrr package has a wide range of applications, as it can be used for various target nuclei, solution- and solid-state NMR data, and high-resolution magic-angle-spinning (HRMAS, gel-state NMR) data.<h4>Summary</h4>NMR spectroscopy is a useful tool for the detection and identification of molecular structural information and has increasing applications in environmental sciences. However, the outputs from NMR instruments contain many differences and require extensive post-processing, creating barriers to their use and application by nonspecialists. The nmrrr package processes and visualizes the spectral data obtained from one-dimensional solution- and solid-state NMR experiments. It also performs the relevant calculations commonly applied in natural organic matter communities, such as computing the relative abundances of various functional groups. In the publication below, the package’s installation, dependencies, and functions are documented, and a standard workflow for processing NMR data is presented. This package is currently available on CRAN and GitHub, and community contributions are welcome.<h4>Contact</h4>Kaizad F.

An R Package for NMR Data Processing

The team of Professor&nbsp;<a target="_blank" rel="noopener noreferrer" href="https://hocek.group.uochb.cz/en">Michal Hocek</a> at IOCB Prague explores the limits of the structure and function of DNA and successfully pushes forward known boundaries. An article presenting the results of their latest research has just been published in the major scientific journal Nucleic Acids Research. They prove that even heavily modified double helices of DNA are stable enough to be used for special applications. This discovery might expand the possibilities of utilizing modified DNA, for example, in medicine.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/UOCHB_Tomas_Bellon_Scientists_from_IOCB_Prague_are_pushing_the_limits_of_DNA_b5c448f9a9.jpg" alt="ÚOCHB: Scientists from IOCB Prague are pushing the limits of DNA." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_UOCHB_Tomas_Bellon_Scientists_from_IOCB_Prague_are_pushing_the_limits_of_DNA_b5c448f9a9.jpg 245w," sizes="100vw" width="1910" height="1000">DNA consists of two long negatively charged chains that hold together even though they repel each other. This is made possible by what is known as stacking interactions and base pairing. Michal Hocek and his colleagues advanced the known limits when they modified DNA by adding an extra negative charge to each letter of the genetic code. This doubled the repulsive forces, yet the DNA double helix remained stable. They also found that such modified DNA not only holds together but that it can also be synthesized or replicated and sequenced using the enzyme DNA polymerase."Think of DNA as a scaffold on which you can attach various chemical compounds with different functions. These are small molecules, such as side chains of amino acids, which occur naturally only in peptides and proteins. In current medicine, we are able to use these molecules only to a relatively limited extent. The reason is that they are markedly unstable and get decomposed rapidly when inside an organism. One solution to this would be a stable skeleton to which they could be firmly attached. And DNA could be just such a base structure in the future," says Prof. Michal Hocek.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/UOCHB_Tomas_Bellon_Scientists_from_IOCB_Prague_are_pushing_the_limits_of_DNA_Prof_Michal_Hocek_Distinguished_Chair_and_head_of_Bioorganic_and_Medicinal_Chemistry_of_Nucleic_Acids_0a8c924ac4.jpg" alt="ÚOCHB / Tomáš Belloň: Prof. Michal Hocek, Distinguished Chair and head of Bioorganic and Medicinal Chemistry of Nucleic Acids." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_UOCHB_Tomas_Bellon_Scientists_from_IOCB_Prague_are_pushing_the_limits_of_DNA_Prof_Michal_Hocek_Distinguished_Chair_and_head_of_Bioorganic_and_Medicinal_Chemistry_of_Nucleic_Acids_0a8c924ac4.jpg 234w," sizes="100vw" width="1500" height="1001">The aim of this research carried out at IOCB Prague is to create DNA molecules that will mimic other chemical compounds. This would enable us to leverage the medicinal potential of certain biomolecules that are difficult to retain in the body. Examples of such biomolecules are the already mentioned peptides or proteins.The Hocek group has already made significant progress, although research in this direction is at its beginning worldwide. The team has, for example, succeeded at developing a novel modified aptamer, which is a short DNA sequence that can bind to a specific target molecule, most frequently a protein. Aptamers have similar properties to antibodies, but they are much more stable. For this reason, aptamers can potentially replace antibodies employed in medicine. However, the number of approved therapeutic aptamers globally can still be counted on the fingers of one hand.The current research exploring the limits of DNA is part of a larger project led by Michal Hocek, for which he has secured a prestigious EXPRO grant from the Czech Science Foundation. This is the second time its results have drawn interest from the journal Nucleic Acids Research. Previously, scientists from IOCB Prague published a method for the enzymatic synthesis of fully artificial DNA. During this synthesis, all nucleotides forming natural DNA are replaced by their modified versions with attached hydrophobic (i.e. water-repelling) molecules.

In this webinar we provide an introduction to the new patented Emission Suppression Technology (EST) for the Thermo Scientific Argus VI Static Vacuum Mass Spectrometer.
EST revolutionizes noble gas isotope ratio mass spectrometry by switching off ionization during sample introduction, removing the trade-off between precision and equilibration time.
We will demonstrate how by pausing sample consumption, EST allows measurements to be made on properly equilibrated samples, resulting in dramatic improvements in both the accuracy and precision of noble gas isotope ratios. We explain the potential that this technology has for dramatically boosting signal sensitivity through modification of prep benches and sample introduction methods.

Thermo Scientific: Unlocking Information from Geological Samples with Carbon, Nitrogen, Sulfur and Hydrogen

Introduction to the answers provided by geosciences samples and why scientists use elemental analysis and IRMS to find those answers.

Unlocking Information from Geological Samples with Carbon

We present the first nitrogen isotopic and trace element analyses from during a “Snowball Earth” glaciation, and suggest they indicate oxidative continental weathering and mildly oxygenated marine waters.
Specifically, we measured three sections of the Ghaub formation, which is the Marinoan glacial unit in northern Namibia. The Marinoan is the second of two Cryogenian Snowball Earth glaciations.
In all sections, we analyzed δ15N values and redox sensitive trace elements, including U, V, and Mo. All measured units are from a marginal marine environment. Two sections are synglacial; one composed of detritial siliciclastics and one of detrital carbonate, both with a minor clay fraction. The third section was deposited during the terminal deglaciation and is comformably overlain by the basal Ediacarab Keilberg cap dolostone.
Trace element data demonstrate two key observations. First, the presence of trace elements in a marine setting is consistent with delivery from the continents via oxic weathering. Active weathering occurred on the continents during Snowball Earth. Secondly, enrichments are consistent with mildly oxygenated subglacial ocean waters.
δ15N values from both synglacial sections range from +1 to +3‰, consistent with small but persistent volumes of oxygenated water. Most dissolved N was NH4+ from N-fixing (δ15N =0‰), with small reservoirs of NO3-. Denitrification of NO3- enriched the oceanic N isotopes a few per mil. An increase in oxygenated water during the deglaciation was accompanied by increased NO3- and denitrification, causing δ15N values to increase to near modern levels. Deglacial values are thus more enriched, between +3 to +5‰.

Uranium-lead geochronology provides valuable insight into the timing and rates of various geological processes throughout Earth’s history.
Isotope dilution thermal ionization mass spectrometry is the most precise and accurate technique for U-Pb geochronology. This technique is generally applied to single zircon crystals or crystal fragments yielding small amounts of Pb (typically &lt; 100 pg) and U (approximately 1 ng) following separation by chromatographic techniques in a very clean environment. Precise and accurate analysis of such small samples requires sensitive ion detection systems.
For higher spatial resolution, in-situ analysis by laser ablation ICP-MS is the preferred method allowing routine, high sample throughput U-Pb dating. For challenging zircons with low U and Pb content, high sensitivity is crucial.
The combination of U-Pb with the Lu-Hf chronometer in zircon is a very powerful and commonly used tool in the geosciences for investigating the processes that control crust-mantle evolution and their timing. Laser ablation multicollector ICP-MS enables determination of high precision in-situ Lu-Hf data required for reliable interpretation.
This webinar highlights the latest advances in U-Pb and Lu-Hf analysis of zircons by Isotope Dilution TIMS, as well as in-situ laser ablation sector field, single collector and multicollector ICP-MS, with a focus on optimizing methodologies using recent development such as the Thermo Scientific™ 1013 Ω Amplifier Technology™ and the Jet Interface.

The beverage industry suffers from fraudulent activities that include incorrect labeling of products and adulteration, which has a significant impact on consumer safety, brand names, and reputation.
Stable isotope measurements can differentiate between beverage samples that otherwise share identical chemical composition. This differentiation is given by the isotope fingerprints. The isotope fingerprint in beverage products is region- or process-specific, which means that products can be differentiated based on geographical region (e.g. wine or tequila ), agricultural sources (e.g. whiskey), and brewing processes (e.g. sake). Fraudulent practices such as mislabeling, sugar addition, or watering of wines and spirits can be unraveled.

Thermo Scientific: Beverage Fraud Prevention using Isotope Fingerprints

Beverage Fraud Prevention using Isotope Fingerprints

The beverage industry suffers from fraudulent activities that include incorrect labeling of products and adulteration.

Isotope fingerprints of nitrogen, carbon and sulfur are a powerful tool to interpret the diet, movement, and mobility of populations in archaeology and ecology studies. Typical sample materials are bone collagen or dentine. The challenge for sequential δ15N, δ13C and δ34S analysis of such samples is driven by extremely low concentration of sulfur (typically &lt;0.3 weight % S), and the samples are often rare and size limited.
This presentation will describe how we have optimized our Thermo Scientific EA IsoLink System with the new High Performance Kit for sulfur analysis to allow for high precision and accuracy NCS analysis.
