The international standard ISO/IEC 17025 [1] clause 7.7.2 with regards to ensuring the validity of results, requires a laboratory to participate in proficiency testing (PT) and/or to participate in interlaboratory comparisons (ILCs) other than PT. However, no guidance as to what these other ILCs might be, or indeed how they might compare in relation to PT, is provided. This leaflet aims to outline other ILCs available, pointing out some of the limitations as compared to PT.&nbsp;There are three major types of ILCs in which a group of laboratories analyses identical portions from a homogeneous, stable test sample, with each type being characterized by its intended purpose [2,3]:<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Eurachem_Interlaboratory_comparisons_other_than_proficiency_testing_2_d9263807fb.jpg" alt="Eurachem: Interlaboratory comparisons other than proficiency testing" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Eurachem_Interlaboratory_comparisons_other_than_proficiency_testing_2_d9263807fb.jpg 245w," sizes="100vw" width="1507" height="607">A key point is that PT is an ILC that is designed to specifically evaluate the performance of participants, providing them with an infrastructure to monitor and assess the validity of their results. This is not the key purpose of the two other ILCs, and thus depending on their intended purpose they have a number of limitations that laboratories need to be aware of when using them rather than PT. Only proficiency testing should have been conducted in full compliance to the competency standard ISO/IEC 17043 [4].&nbsp;<h4>Evaluation of measurement procedure performance&nbsp;</h4>These ILCs, are designed to assess how a particular measurement procedure performs and whether it is fit for its intended purpose. These ILCs are often referred to as a ‘method performance study’ or a ‘collaborative study’ [2]. Some limitations of using such ILCs for monitoring laboratory performance as an alternative to PT are:&nbsp;<ul><li>All participants use the same measurement procedure i.e. the measurement procedure that is being validated. Unless the measurement procedure is being routinely used by the participating laboratory such an ILC will not assess the routine performance of the laboratory using their own routine measurement procedure. Nor does it enable them to compare their performance with other laboratories using alternative measurement procedures.&nbsp;</li><li>The measurement procedure is likely to be new, so participants may not have established stable procedures and quality control, so performance may not reflect routine use.&nbsp;</li><li>The report from such an ILC would not provide information on the performance of the participant, if the statistical model used makes the assumption that all laboratories perform with equal variability.</li><li>The design of the study may require the participants to assess multiple samples and/or to undertake multiple replicate analysis on the test materials. This may not be representative of the routine measurements or tests undertaken by the laboratory.&nbsp;</li><li>The conclusion of the ILC might be that the measurement procedure being assessed is not valid.&nbsp;</li></ul><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Eurachem_Interlaboratory_comparisons_other_than_proficiency_testing_3_a53ecd2f5d.jpg" alt="Eurachem: Interlaboratory comparisons other than proficiency testing" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Eurachem_Interlaboratory_comparisons_other_than_proficiency_testing_3_a53ecd2f5d.jpg 157w," sizes="100vw" width="570" height="566"><h4>Characterisation of candidate reference materials&nbsp;</h4>These are ILCs that assign a property value to a candidate reference material, usually with a stated measurement uncertainty. These are often referred to as a ‘material certification study’ [2]. Limitations of using such ILCs as an alternative to PT are:&nbsp;<ul><li>The analysis of the candidate reference material is likely to require additional care in exercising the routine measurement procedure, such as substantially more replication, and/or may require quite different reporting formats (e.g. all valid replicates instead of a mean result). Thus, such an ILC will not necessarily provide an evaluation of the performance of the laboratory based on the routine use of their measurement procedures.&nbsp;</li><li>The report from such an ILC may include the results from the participating laboratories but would not provide information on the performance of each laboratory.&nbsp;</li><li>Participating laboratories may be required to assess multiple samples and/or to undertake multiple replicate analysis on the candidate reference materials. Thus this may not be representative of the routine measurements or tests undertaken by the laboratory.&nbsp;</li></ul><h4>Other ILCs&nbsp;</h4>Some other ILCs, whilst not being conducted in full compliance of the requirements of ISO/IEC 17043, may be designed to evaluate participant performance. These would include small ILCs as defined by EA‑2/21 [5] or split sample ILCs i.e. where a portion of a single sample is sent to two or three laboratories. Whilst these ILCs are specifically designed to evaluate participant performance, they may not provide a comprehensive comparison that a PT might provide. In such cases the laboratory needs to evaluate carefully the competence of the organization managing the ILC and the suitability of the service externally provided (ISO/IEC 17025 clause 6.6).

Agilent Technologies: Analysis of High Purity Titanium Using an <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=10&amp;search=9500">Agilent 9500 ICP-QQQ</a></h3>Ensuring purity and performance of titanium materials used in high-tech industries&nbsp;<ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_high_purity_titanium_9500_icp_qqq_5994_9024en_agilent_56ab5e943b.pdf">Full PDF for download</a></li></ul><h5>Importance of high-purity titanium and the role of ICP-QQQ&nbsp;</h5>High-purity titanium (Ti) is a critical material in high-tech industries such as semiconductor manufacturing and aerospace engineering. In semiconductor applications, Ti is widely used as a sputtering target for thin-film deposition, where even trace levels of impurities can negatively affect film uniformity, electrical properties, and device reliability. In aerospace applications, Ti is valued for its high strength-to-weight ratio and corrosion resistance, making it an ideal material for engine components and structural parts. However, any impurities can compromise the mechanical integrity and diminish the long-term performance of components, especially when operating under extreme conditions.Ensuring the reliability and functionality of Ti in these demanding environments requires precise quantification of trace impurities in the raw material. Triple quadrupole Inductively Coupled Plasma Mass Spectrometry (ICP-QQQ) provides robust suppression of spectral interferences and ultra-low detection limits (DLs), enabling accurate determination of impurities at or below the 1 mg/kg (ppm) level in the solid. This level of sensitivity is particularly important for quality control (QC) of high-purity Ti, where conventional techniques such as XRF, ICP-OES, and GD-MS lack the sensitivity and DLs.&nbsp;For unrivalled interference reduction using reactive cell gases, Agilent ICP-QQQ instruments include two unit mass (1 u) quadrupole mass filters, Q1 and Q2.1 Q1 is positioned before the collision/reaction cell (CRC) to select which ions enter the cell for reaction with the cell gas. Q2 filters ions that exit the cell before they pass to the detector. This tandem mass spectrometer (MS/MS) operation allows for unmatched control of reaction chemistry in the CRC, making the technique useful for handling intense spectral interferences, including polyatomic, doubly charged ion (M++), isobaric, and peak overlap interferences.&nbsp;Using the newly developed <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/library?mainauthorItems=10&amp;search=9500">Agilent 9500 Triple Quadrupole ICP-MS</a> featuring a Dual-Cell System (DCS) CRC and equipped with an optional m-lens, analysts can confidently analyze Ti matrix samples and verify material purity over extended measurement periods. The m-lens is designed with an optimized geometry that minimizes background signals from easily ionized elements that can deposit on interface components during long runs. This feature enables the instrument to maintain high-power, matrix-tolerant plasma conditions while achieving ultralow background equivalent concentrations (BECs), which is critical for ppt-level impurity analysis. Operating the DCS with a suitable cell gas effectively controls spectral interferences from Ti-based species (Ti²+ and TiO+ ) that impact elements like sodium (Na), magnesium (Mg), copper (Cu), and zinc (Zn). Together with the m‑lens, this approach ensures accurate measurement of trace elemental impurities, enabling compliance within stringent industry standards. The effectiveness of the m‑lens in minimizing background signals and enabling ppt‑level impurity analysis under robust plasma conditions has also been demonstrated in high-matrix applications using ICP‑QQQ.2, 3 In addition to interference control, the 9500 ICP-QQQ system’s robustness and reproducibility make it well suited for routine analysis in both research and production settings. This capability supports the continued advancement of high-tech applications that rely on ultra-clean titanium.In this study, a 200 ppm Ti solution prepared from a high-purity Ti powder was used to represent a typical sample encountered in advanced material analysis. The performance of the 9500 ICP-QQQ for quantifying trace impurities, including Na, Mg, Cu, and Zn, in a high Ti matrix was assessed through spike-recovery experiments and long-term stability tests.<h4>Conclusion&nbsp;</h4>This study demonstrated the effectiveness of the Agilent 9500 ICP-QQQ with m-lens for the ultra-trace analysis of impurity metals in high-purity titanium. By applying optimized reaction gas conditions and mass-shift techniques, spectral interferences from Ti-based species such as Ti²+ and TiO+ were successfully mitigated, enabling accurate quantification of elements like Mg, Cu, and Zn.&nbsp;The method achieved limits of quantification in the sub-ppm range for the undiluted Ti digestion solution and maintained stable ISTD signals over extended measurement periods. Spike recovery tests confirmed high accuracy and reproducibility, with most elements showing recoveries within ±10% and RSDs below 3%.&nbsp;These results confirm that the 9500 ICP-QQQ is a robust and reliable tool for quality control of high-purity Ti, supporting its critical applications in semiconductor and aerospace industries where impurity levels must be strictly controlled.<h3>2.

Thermo Fisher Scientific: Enhancing Monoclonal Antibody Yield and Quality Through Automated Multi-Component Feedback Control Loops Using the MarqMetrix All-In-One Process Raman Analyzer</h3><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/labrulez-bucket-strapi-h3hsga3/enhancing_monoclonal_antibody_an1506_en_bba763e865.pdf">Full PDF for download</a></li></ul>The application of Raman spectroscopy for real-time monitoring and control of bioreactors marks a significant advancement in bioprocessing technology. Over the past decade, its adoption has enabled tighter control of critical process parameters (CPPs), offering early indicators of process performance to ensure consistency and improve product quality. Raman spectroscopy leverages the unique vibrational signatures of molecules, allowing for highly specific detection even in complex biological matrices. This enables simultaneous, real-time monitoring of multiple CPPs, including nutrient concentrations, metabolic by-products, and cell density. As a result, users gain deep, real-time insights into cellular metabolism and can implement more dynamic, adaptive feeding strategies based on metabolic network understanding.&nbsp;Previous studies have demonstrated the negative impact of high lactate on cell health and quantity and quality of titer produced.² In this study, we demonstrate the successful implementation of process Raman analyzer for simultaneous multi-component feedback control of glucose and lactate in a bioreactor. By continuously monitoring both analytes, the feedback control loop dynamically maintained a constant total carbon concentration (glucose + lactate) at a setpoint of 2 g/L.&nbsp;This advanced carbon-source-based control strategy ensured that cellular metabolic demands were met while promoting lactate consumption toward the end of the run. As a result, lactate accumulation was significantly reduced, leading to substantial improvements in titer yield, product quality, and cell viability compared to standard bolus feeding strategies (Figure 2).The outcomes of this work underscore the <a target="_blank" rel="noopener noreferrer" href="https://icpms.labrulez.com/products/2233">Thermo Scientific™ MarqMetrix™ All-In-One Process Raman Analyzer </a>as a key Process Analytical Technology (PAT) tool-enabling real-time, multi-analyte control for any biomanufacturer seeking to engage in intelligent, automated biomanufacturing.<h4>Conclusion&nbsp;</h4><h5>1. Unmatched Real-Time Control Capability:&nbsp;</h5>Maintaining a constant total carbon concentration (glucose + lactate) of 2 g/L in dynamic bioreactor environments demands precise, simultaneous analyte monitoring. The MarqMetrix All-In-One Process Raman Analyzer delivers near real-time, high-fidelity data every two minutes, empowering advanced control strategies that are simply not feasible with conventional technologies. This makes it an indispensable PAT tool for modern bioprocessing.&nbsp;<h5>2. Proven Impact on Product Yield and Quality:&nbsp;</h5>The Raman-enabled carbon control strategy resulted in a &gt;10% increase in titer and a reduction in glycation by 83% and 66% compared to continuous and fed-batch glucose control, respectively. These outcomes underscore the analyzer’s transformative impact on both product quantity and quality.&nbsp;<h5>3. Versatile Automation Across Bioprocesses:&nbsp;</h5>All three bioreactor runs—each employing distinct control logics (Table 2)—were successfully managed through automated feedback using the process Raman analyzer. Its flexible design, including easily swappable probes, supports seamless adaptation to other critical metabolites such as amino acids, making it a universal solution for bioprocess control.&nbsp;<h5>4. Foundation for Intelligent Manufacturing:&nbsp;</h5>With its real-time, data-rich insights and seamless integration into automated systems, the MarqMetrix All-InOne analyzer is not just a monitoring tool; it is a cornerstone technology for intelligent, AI-driven biomanufacturing.

News from LabRulezICPMS Library - Week 27, 2026

Scientists from CEITEC Brno University of Technology led by Markéta Kaiser have achieved a globally unique breakthrough in coral research. Using the live microCT method, they were able, for the first time ever, to observe the growth of living marine corals in real time and reveal the processes behind the formation of their calcium carbonate skeletons, which had previously remained hidden beneath the surface. The results of the international study, published in the prestigious journal Science Advances, show how corals grow, regenerate, and respond to stress and competing organisms.The <a target="_blank" rel="noopener noreferrer" href="https://www.science.org/doi/10.1126/sciadv.aee3183">study</a> was carried out through a collaboration between researchers from Brno, Vienna, and several other international institutions. A key role was played by the X-ray Micro and Nano Computed Tomography Laboratory (CTLAB) at CEITEC BUT, where all the crucial data and three-dimensional coral models were produced. CEITEC also shares both the first and corresponding authorship of the study.“Thanks to live microCT, we were able, for the first time, to observe what happens beneath the surface of a coral skeleton,” explains Markéta Kaiser from CTLAB at CEITEC BUT. “For example, we witnessed situations where a coral, after being attacked by algae, completely halted its normal growth and began building a protective wall around the threatened area. Once the danger had passed, it was able to resume its original growth pattern.”<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/CEITEC_Zivi_korali_jezdili_vlakem_z_Vidne_do_Brna_Vedci_diky_nim_odhalili_jejich_tajny_zivot_540e183e84.jpeg" alt="CEITEC BUT/Jakub Rozboud: Live Corals Traveled by Train from Vienna to Brno.

The team had to develop a special system that enabled living corals to be safely scanned directly in seawater. The coral colonies regularly traveled by train from Vienna to Brno for measurements and, after several hours, were transported back to professional aquarium systems in Vienna.“At first, it seemed like a somewhat crazy idea. No one knew whether living corals could withstand repeated scanning,” says Kaiser. “Gradually, however, we found that they survived, continued to grow, and provided us with unique data.”<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/CEITEC_Zivi_korali_jezdili_vlakem_z_Vidne_do_Brna_Vedci_diky_nim_odhalili_jejich_tajny_zivot_2_fcbb29a4f6.jpeg" alt="CEITEC BUT/Jakub Rozboud: Live Corals Traveled by Train from Vienna to Brno.

Using longitudinal live microCT, we tracked the same coral colonies over weeks to months at micrometer resolution. Coral skeleton formation is not a uniform accretion process but a dynamic integration of multiple programs, including vertical and horizontal patterned growth, previously undescribed defensive wall-building against competitors, exploratory edge behavior with reversible expansions and retractions, and skeletal regeneration favoring rapid, imprecise yet effective matrix expansion. Time-resolved imaging links colony-scale growth to microscale events, showing that all modes depend on balances between fusion of skeletal microparticles and layered matrix deposition, guided by tissue prepatterning. Beyond corals, this framework generalizes to studying skeletal dynamics across diverse biomineralizing organisms.

This webinar aims to demonstrate how UV-visible spectroscopy can be used as a powerful tool to understand solid catalysts, specifically the class of supported oxide catalysts.&nbsp;Supported oxides consist of an active oxide phase supported on a carrier particle, often of alumina or silica.These catalysts are used extensively in the chemical industry and in pollution abatement. These materials also have electronic spectra (e.g. from UV-visible spectroscopy) that are very sensitive to the local structure, oxidation state, and chemical environment of the catalytic oxide component. UV-visible spectroscopy does not require crystalline material, and research-grade spectrophotometers are more than sufficiently sensitive to detect very low loadings of oxides on the carrier particles or to observe small changes to the structure. Using a praying mantis accessory, we provide some examples of how the UV-visible spectra of iron, copper, zirconium, titanium, manganese, and other oxides are key to understanding their catalytic activity. In some cases, we can also utilize an in situ reactor to understand how the structure of the active oxide changes at high temperatures and with reactive gases.<h4>Key Learning Objectives:</h4><ul><li>Guidelines for UV-Vis-NIR spectrophotometric diffuse reflectance measurement.</li><li>Considerations when doing in situ UV-visible diffuse reflectance spectroscopy.</li><li>Properties of catalytic materials used in the sustainable production of chemicals and fuels and pollution abatement.</li><li>Utilizing spectroscopy in conjunction with simulation, kinetics, and other characterization tools for the development of improved structure-function relationships.</li></ul><h4>Who Should Attend:</h4><ul><li>Under/Post Graduate Researchers/Students</li><li>Laboratory Managers</li><li>Scientist/Staff Scientists</li><li>Lab Technician/Technologist</li><li>Analysts</li><li>Commercial or academic organizations in the field of catalytic materials, including metal-organic frameworks (MOFs) and oxides, or the field of chemical transformations, including selective oxidations, dehydrogenation, NOx abatement, biomass conversion, and others</li></ul><blockquote>Presenter: Justin M.

Thermomechanical analysis (TMA) is used to measure the dimensional changes, or deformation, of a sample as it is heated or cooled and subjected to a defined stress or load. It determines expansion, shrinking, and softening behavior on materials such as films, laminates, solids, and fibers. The technique is also very useful for measuring relaxation effects that are often not detected by DSC.The TMA TechniqueIn a typical TMA experiment, the sample is placed on the sample support and a constant load is applied via a measuring probe. The probe remains in contact with the sample and moves up or down as the sample expands or contracts with a change in temperature. The displacement of the probe is measured by means of a sensor. The sample set-up and applied load vary depending on the measurement mode and the information required.Thermal expansion or shrinkage, as well as the deformation or stiffness of the material, can be determined based on the set-up and measured displacement. Typical properties of interest determined by TMA are the glass transition, coefficient of thermal expansion (CTE), and Young’s modulus.TMA is a versatile technique that can be used to study a wide range of materials, including polymers, composites, ceramics, metals, and biomaterials. It is commonly used in material research, quality control, and failure analysis applications.Join our live webinar to learn all about TMA and don’t miss the opportunity to ask our experts your questions!Event Program<ul><li>Basic principles of TMA</li><li>Important instrument components</li><li>Measurement modes (dilatometry, penetration, tension, swelling, dynamic load, bending)</li><li>Why you should use TMA for your analysis</li><li>Application examples for different industries</li></ul><blockquote>Presenter: Nicolas FedelichWith a background in chemical engineering, Nicolas joined METTLER TOLEDO in 2009 as an application specialist for Thermal Analysis.

Thermomechanical Analysis (TMA)

Consumer products are complex mixtures that rely on careful formulations and precision chemistry to deliver the desired properties. These properties can be chemical (such as the peroxide content of an oxidizer), physical (such as polymer viscosity) or fungible (such as the reserve acidity of a mixture). Measuring these and other types of properties typically requires a fleet of instrumentation and is often limited to raw material input and final product testing. These testing throughput limits place a high burden on the analytical lab, making product improvement difficult. &nbsp;Near-infrared spectroscopy (NIR) is a laboratory tool that can relieve the throughput limitation and be deployed to multiple products and problems at the same time.&nbsp;Register for this webinar to hear Alex Mattingly, Product Specialist at Chemlink Laboratories, explain how he uses NIR to address manufacturing challenges and increase production efficiency. He will show how he implemented NIR and developed the analytical methods to replace complex wet-chemical assays.

The complete Solution for Food Analysis: Presented by Retsch, CEM, Shimadzu and EltraAccurate and rapid food analysis is becoming increasingly important as regulations become stricter and consumers become more demanding. This expert day on food analysis will give you a comprehensive overview of the optimal steps from sample preparation to analysis, familiarize you with modern methods and bring you up to date.Registration is free of charge and without obligation.<div><h3>Reproducible sample preparation for food analysis&nbsp;</h3>Food occurs in different consistencies and is often inhomogeneous. For meaningful analysis, food laboratories require representative samples, which makes homogenization necessary as part of sample preparation.Ideally, this step should involve as little work as possible. The prepared subsample must represent both the laboratory sample and the initial sample. This would not be the case with an inhomogeneous sample, as some components of the initial sample could be over- or under-represented.</div><h5>In this webinar you will learn more about:</h5><ul><li>Homogenization, standard deviation, correct analysis values</li><li>How do I find the optimal method for my sample</li><li>Cryogenic grinding (dry ice, liquid nitrogen)</li><li>Suitable laboratory mills for homogenizing foodstuffs</li><li>Live demos of selected mills</li><li>Application examples</li><li>Grain size determination using sieve analysis</li></ul><blockquote>Presenter: Dr. Tanja Butt, Dr. Lena Weigold and Dr. Gerhard Beckers</blockquote>This webinar is part of a series of four webinars (Retsch, CEM, Shimadzu, Eltra).
