Researchers&nbsp;Tereza Nešporová and Jaroslava Večerková from Brno's RECETOX explain why failures are also a valuable part of gaining knowledge, how they study the effects of chemical substances on the hormonal system, and why they apply their professional insights to their everyday lives.<h5>How did you get involved in research at RECETOX?&nbsp;</h5>Jaroslava: I actually joined RECETOX by chance during my follow-up Master's studies in Environmental Chemistry, back when Professor Holoubek was still leading the institute. I wrote my thesis under Klára Hilscherová and simply stayed here ever since, except for a break during maternity leave. I have been part of her team the whole time, focusing on endocrine disruptors.&nbsp;What has changed over the years is the focus of our research. We used to study surface waters, particularly the presence of substances with endocrine-disrupting potential and their effects on organisms. Today, the research has shifted more toward humans and the interactions between chemical substances and the endocrine system.&nbsp;Tereza: I came from a completely different field. I studied molecular biology and worked on chronic lymphocytic leukemia for my Master's thesis at CEITEC. I used genetic engineering methods such as CRISPR/Cas9 for gene editing—activating, suppressing, or completely removing genes.&nbsp;At the time, Klára Hilscherová’s group needed to create cellular models with increased production of deiodinase enzymes, which I still work on today. I had heard only positive things about the team, and when I finished my Master's degree, I wanted to move beyond my original field. The connection between hormones and neurodevelopment attracted me, and RECETOX became the obvious choice.&nbsp;<h5>So you are in the same research team. How do you collaborate?&nbsp;</h5>Tereza: We sit in the same office. And that’s probably the main thing (laughs).&nbsp;Jaroslava: We discuss things a lot. Some mechanisms repeat across experiments, so we talk about how each of us evaluates data and why. We inspire each other, even though we do not directly collaborate on the same laboratory work.&nbsp;<h5>How does your work differ?&nbsp;</h5>Tereza: Our team is highly interconnected. We all work on developing assays for detecting endocrine-disrupting substances, specifically those affecting thyroid hormones. However, each of us focuses on a different part of the system.&nbsp;I focus on deiodinase enzymes, which regulate the activation and deactivation of hormones. Recently, I have been spending more time analyzing data and designing experiments than working directly in the laboratory.&nbsp;Jaroslava: Within the team, I mainly participate in testing different types of samples—from individual chemicals and mixtures to real environmental samples such as household dust—using the assays mentioned above.&nbsp;It is important to note that chemicals can affect the hormonal system at different levels. They can bind to or block nuclear receptors, affect hormone transport in the bloodstream, or interfere with hormone metabolism. In the past, only one part of this process was monitored. Today, we aim to cover the full spectrum of these interactions.&nbsp;Tereza: And that is crucial. A substance may appear negative in one test, yet affect another part of the system, producing a significant impact on the organism. That is why current research focuses on the entire range of possible mechanisms.&nbsp;<h5>Why did you choose endocrine disruptors as your research topic?&nbsp;</h5>Jaroslava: For me, it was more or less a coincidence while choosing my thesis topic. But it turned out to be a fascinating area, so I stayed with it.&nbsp;Tereza: I had been interested in it for a long time. I also like that our work has a concrete outcome—we develop tests that can realistically be used in decision-making regarding the safety of chemical substances. Compared to my previous research, I feel this work has a much more direct application.&nbsp;<h5>What about your PhD studies?&nbsp;</h5>Jaroslava: My PhD studies are currently on hold. After maternity leave, I returned as a laboratory technician, and my project work gradually shifted away from my original doctoral topic.&nbsp;Tereza: I am currently in the fourth year of my PhD studies. I also completed a research stay in Germany, where I learned to work with neuronal cells.&nbsp;As part of my studies, I focus mainly on deiodinases—the enzymes that act as the “on and off switches” of thyroid hormones. We are developing a test that can measure the effects of chemical substances on their activity.&nbsp;In addition, we are now studying how these substances affect neurons and their development, because proper thyroid hormone levels are crucial for nervous system development.&nbsp;<h5>What is the most challenging aspect of laboratory work?&nbsp;</h5>Tereza: Probably unpredictability. Cells do not always grow as expected, instruments have their bad days, and human error also plays a role. The important thing is to document all mistakes and complications and learn from them.&nbsp;Jaroslava: I agree with Tereza. The biggest challenge is unpredictability. Cells are living systems and do not always behave the same way.&nbsp;<h5>Can a career in science be combined with parenthood?&nbsp;</h5>Jaroslava: At RECETOX, definitely. There is a great deal of flexibility, and managers are very supportive. When necessary, it is possible to work from home. We help each other a lot within the team.&nbsp;Tereza: It also depends on the type of work and whether it can be planned according to your needs. Our team collaborates closely and tries to help one another whenever necessary. That is key. And when needed, data analysis and manuscript writing can also be done from home.&nbsp;<h5>Is your work more routine or highly varied?&nbsp;</h5>Jaroslava: Very varied. Laboratory work alternates with computer-based work. We are constantly learning new things. It is definitely not repetitive or boring, and that is what I enjoy about it.&nbsp;Tereza: The only routine in my work is taking care of cell cultures. Otherwise, the work is constantly changing. That is also what I enjoy most about it.&nbsp;<h5>What are the biggest challenges in your work?&nbsp;</h5>Jaroslava: Data evaluation. Measuring something is one thing; evaluating and interpreting it correctly is another.&nbsp;Tereza: Implementing new methods. And also those moments when you do everything correctly according to a published protocol, yet the results still do not match expectations.&nbsp;In science, you have to learn to accept that not everything works the first time. The important thing is not to give up, to continue optimizing, and to keep hoping for success.&nbsp;<h5>What role should open science play?&nbsp;</h5>Tereza: A huge one. If we had access to detailed protocols and original datasets, it would save enormous amounts of time and money during the implementation and optimization of new methods. Scientific papers often omit details that are actually critical for experimental success.&nbsp;Jaroslava: It is also important to share failures. A negative result is still a result, and it can provide valuable information.&nbsp;<h5>You are both mothers. Does your work influence your personal lives?&nbsp;</h5>Jaroslava: Absolutely. For example, we pay close attention to washing fruit because of chemical treatments. I encourage my children to think about what they consume, what it contains, and where it comes from. We try to avoid plastics and consistently separate waste.&nbsp;Tereza: Definitely. Even before having a child, I paid close attention to the composition of cosmetics, food, and other products. After becoming a parent, my caution multiplied.&nbsp;I was especially careful during pregnancy because a developing organism is most sensitive to harmful substances. Sometimes relatives raise their eyebrows at this, but when we have information firsthand, we cannot simply ignore it.&nbsp;Jaroslava: We also pay attention to toys, clothing, and materials used in the home. It is a kind of professional deformation (laughs).&nbsp;<h5>How can your research contribute from a broader perspective? How can others build upon it?&nbsp;</h5>Jaroslava: We are gradually optimizing methods that may eventually be used routinely. That is probably our greatest contribution.&nbsp;Tereza: Yes, our methods could help identify undesirable effects of substances before they reach the market, potentially leading to regulation of their production.&nbsp;<h5>Would you like to continue working on this topic in the future?&nbsp;</h5>Jaroslava Večerková: The topic of endocrine disruption is extremely interesting and very broad. The direction of research may change depending on current projects, but I would like to remain part of the team.&nbsp;Tereza Nešporová: I am very interested in uncovering how substances affect human health, and I believe I will want to continue working in this area. I like how dynamic the research is and that it has direct practical applications. I do not mind change, but I am happy within this team and would like to stay. We work together as a well-coordinated group.&nbsp;

Agilent Technologies: Operational efficiency for your GC and GC/MS labs with the Agilent 8860B gas chromatography system</h3><ul><li>Brochure</li><li><a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/br_8860b_gc_5994_9206en_agilent_7b7b766cd2.pdf">Full PDF for download</a></li></ul><section><div><div><div><div><div><div>The brochure presents the <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/library?mainauthorItems=10&amp;search=8860B">Agilent 8860B GC system</a> as a routine GC and GC/MS platform focused on operational efficiency, reliable performance, intelligent diagnostics, and sustainability. It is positioned as a next-generation GC workhorse for laboratories that need consistent, high-quality data while increasing throughput and reducing downtime. Key performance features include dual sample injection capabilities, improved repeatability for retention time and peak area, electronic pneumatics control, retention time locking for method transfer, and a built-in oven light to simplify maintenance and column installation.A major theme is instrument intelligence through the Agilent GC Assist interface. The system provides browser-based access to instrument status, methods, sequences, logs, diagnostics, maintenance information, and help resources. Built-in tools such as early maintenance feedback, system health reporting, automated and user-initiated diagnostics, peak evaluation, and self-guided troubleshooting are designed to help laboratories detect issues early, maintain uptime, and reduce the need for expert-level intervention during routine operation.The brochure also emphasizes sustainability and resource management. The 8860B GC includes gas and power usage reporting, method-based monitoring, alerts for abnormal gas use, and tools for detecting possible leaks or restrictions. Agilent highlights helium conservation options, including a helium conservation module that can reduce helium consumption by switching to an alternative gas during idle periods, as well as support for hydrogen and nitrogen carrier gases with built-in hydrogen safety features. These functions are presented as ways to reduce operating costs, conserve resources, and protect workflows from helium supply disruptions.Finally, the brochure describes the broader Agilent GC ecosystem around the 8860B. The system supports multiple inlets, detectors, autosamplers, headspace sampling, single quadrupole GC/MS compatibility, OpenLab CDS, DA Express, MassHunter software, Agilent consumables, columns, and CrossLab services. Together, these elements are presented as a complete workflow for routine laboratories that need flexibility, compliance support, service coverage, method consulting, training, and long-term value from their GC investment.<h3>2. MDCW / University of Washington: Implementing Tile-Based Fisher Ratio Analysis of GC×GC-TOFMS Data to Obtain a Master Peak Table of All Detected Analyte Compounds in Many Petroleum-Based Samples</h3><ul><li>Presentation</li><li><a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/O_9_Halvorsen_136808e314.pdf">Full PDF for download</a></li></ul><section><div><div><div><div><div><div>The presentation describes the development of a chemometric workflow for advanced fuel sample analysis using GC×GC-TOFMS data. The work was carried out by the University of Washington in collaboration with Chevron Technical Center, with the goal of improving the characterization of complex petroleum-based samples. Moving from conventional GC to comprehensive two-dimensional GC increased peak capacity and chromatographic resolution, but also created the need for more advanced methods to generate reliable peak tables across many chemically diverse fuel samples.The key method presented is a tile-based Fisher Ratio approach implemented through <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/products/348">ChromaTOF Tile</a>. This method identifies analytes that show statistically significant concentration differences between sample classes. Instead of relying only on peak detection or manual alignment, the workflow uses chromatographic “tiles” to reduce the impact of retention-time shifting and to capture both major and trace-level components. The study included multiple fuel classes, including hydrobate, reformate, naphtha, FCC gasoline, and blanks.Because Fisher Ratio values alone do not directly indicate whether a compound is truly detectable, the authors added a blank-based p-testing strategy. Three blank chromatograms were used to estimate background signal distributions for each tile, and confidence intervals were then applied to determine whether each detected hit was present in individual sample classes. This produced a master peak table covering 719 hits across nine fuel sample classes. The results showed good reproducibility, with only 6.3% of classifications being heterogeneous across replicates.Overall, the presentation concludes that the tile-based workflow can generate comprehensive and reproducible peak tables with reduced user intervention, while preserving the ability to recover trace analytes in complex petroleum samples. The approach should be broadly applicable to other complex sample types and could also be adapted using chemometric metrics other than Fisher Ratio, depending on the experimental design and analytical goals.<h3>3. Shimadzu / ASMS: Is Your Next Sip Safe? A Simple, Rapid Method for Measuring volatile PFAS in Juices.</h3><ul><li>Poster</li><li><a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/TP_143_Is_Your_Next_Sip_Safe_A_Simple_Rapid_Method_for_Measuring_volatile_PFAS_in_Juices_a6ed9414c0.pdf">Full PDF for download</a></li></ul>Per- and polyfluoroalkyl substances (PFAS) pollution is a growing global concern due to links with adverse health effects, many of which remain poorly understood. 1 Accurate detection and quantification are therefore essential. While PFAS analysis has traditionally focused on water, attention is rapidly expanding to food and beverages, where testing remains limited despite high stakes and increasing regulations. 2 A recent PFAS lawsuit against a juice manufacturer underscored the heightened public scrutiny of PFAS in juices, placing food safety and brand reputation at risk. 3 This study presents a Headspace Solid-Phase Microextraction– Triple Quadrupole Gas Chromatography/Mass Spectrometry (HS-SPME GC/MS/MS) method for PFAS quantitation in juices. GC/MS enables analysis of volatile PFAS unsuitable for LC/MS, while HS-SPME offers rapid analysis with minimal sample preparation in complex matrices.<h4>Methods</h4>A volatile PFAS analysis method was developed on a Shimadzu <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/library?mainauthorItems=1&amp;search=GCMS-TQ8040+NX">GCMS-TQ8040 NX</a> with an <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/library?mainauthorItems=1&amp;search=AOC-6000+Plus">AOC-6000 Plus multifunctional autosampler</a> equipped with a solid phase microextraction (SPME) module (Figure 1).<h4>Results&nbsp;</h4>The system was deemed free of contaminants and inferences. None of the target PFAS in the method blank were found in quantifiable concentration. In the study, the calibration curve for each target included at least seven calibrators. Calibration curve results showed a good linear fit for all compounds with coefficient of determination (R2 ) ≥ 0.993. The linear range and R2 of each PFAS target are shown in Table 3.<h4>Conclusion</h4>Overall, these results demonstrate the robustness and reliability of the method for PFAS analysis in two carton apple juices (Brands X and Y), one plastic bottled apple juice (Brand X), and a berry blend carton juice (Brand X). Given the diversity of matrices evaluated, the method may also be suitable for other beverages, including sports drinks and vitamin-enhanced waters<h3>4. Thermo Fisher Scientific / ASMS: Enhanced sensitivity for the quantitative analysis of pesticides using a GC Orbitrap MS</h3><ul><li>Poster</li><li><a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/po_004706_lsms_pesticides_exploris_gc_efs_po004706_asms2026_na_en_5f51b18742.pdf">Full PDF for download</a></li></ul>Detection of pesticide residues in fruits and vegetables is essential for food safety, but it can be challenging in complex, highly pigmented matrices due to interferences. Orbitrap technology provides high resolution and mass accuracy, enabling confident identification of coeluting and isobaric compounds while reducing false results. Furthermore, the FS-HRAM acquisition enables simultaneous quantitation and screening within a single analysis with the capability of retrospective data analysis, allowing laboratories to reprocess datasets for additional or emerging compounds without re-injecting samples. The <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/products/2419">Orbitrap Exploris GC S mass spectrometer</a> features the Thermo Scientific NeverVent Advanced Electron Ionization Source (NVAEI) which offers an improved design providing enhanced sensitivity and robustness, allowing for increased instrument uptime and maximized sample throughput for rapid return on investment (ROI).<h4>Materials and methods</h4><h5>Data analysis&nbsp;</h5>Data was acquired, processed and reported using the <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/products/76">Thermo Scientific Chromeleon Chromatography Data System (CDS) software</a>, which provides integrated instrument control, automated workflows, and an intuitive interface for data analysis, customizable reporting, and compliant data management in accordance with FDA 21 CFR Part 11 and European Commission (EU) Annex 11. Its advanced reprocessing capability streamlines sequence setup, data review, and reporting offering the possibility to easily flag and check compliance with the current regulations.Results Compliant analyte identification The use of HRAM-GCMS reduces the matrix interferences ensuring a confident and selective identification of analytes (Figure 1). All target compounds satisfied the SANTE criteria at the default MRL of 10 µg/kg and more than 90% were confirmed at concentrations of 1 µg/kg following the SANTE/11312/2021v2026 guidance criteria of:&nbsp;<ul><li>two ions were detected for each pesticide with mass accuracy ≤ 5 ppm with precursor and product ions in the extracted ion chromatograms fully overlapped,&nbsp;</li><li>due to the added value of accurate mass measurement, matching ion ratios is not necessary, however, an ion ratio (IR) deviation within ± 30% (relative) of the average of calibration standards from the same sequence was considered to provide additional support for identification</li><li>retention times (RT) within a tolerance of ± 0.1 minutes</li></ul>Sensitivity performance (IDL) and analytical linearity Instrument sensitivity was evaluated using calculated IDLs derived from replicate injections of low-level, matrix-matched standards. The Orbitrap Exploris GC S demonstrated detection limits at levels at or below 0.5 µg/kg for most of the investigated pesticides (Figure 2). Linear dynamic range was evaluated using matrix-matched calibration curves ranging 0.5–200 µg/kg, with each calibration level injected in triplicate. All target analytes demonstrated excellent linearity, with coefficients of determination (R²) &gt; 0.993, response factor (%RSD) values below 20% across the calibration range, and ion ratios (IRs) within ±30% of the average calibration standard values. System suitability for quantitative analysis was confirmed by calculated concentrations within ±20% of expected values and recoveries ranging from 96% to 104%. An example of calibration curve for Aldrin is shown in Figure 3.<h4>Conclusions&nbsp;</h4>The results obtained in these experiments demonstrate that the Orbitrap Exploris GC S mass spectrometer equipped with NeverVent AEI ion source represents a reliable tool for analysis of pesticides in complex matrices.&nbsp;<ul><li>The Orbitrap Exploris GC S offers a simple approach for the multiresidue analysis of pesticides allowing for full-scan acquisition combined with high mass resolving power&nbsp;</li><li>The NeverVent AEI ion source is designed for ultra-trace concentration detection, making it ideal for challenging applications ensuring detection limits at levels at or below 0.5 µg/kg for most of the investigated pesticides&nbsp;</li><li>Confident identification of compounds can be easily achieved through i). high spectral quality, ii). high spectral fidelity, ensuring consistent spectrum independently from concentration, and iii). consistent mass accuracy irrespectively of analyte concentration and time&nbsp;</li><li>System suitability for quantitative analysis was demonstrated with R2 &gt;0.993, RF %RSD across the entire calibration curve &lt; 20, and IRs within ± 30% of the average of calibration standards, calculated amounts within 20% the expected values, and percentage recovery (%) ranging from 96 to 104.</li></ul></div></div></div></div></div></div></section></div></div></div></div></div></div></section>

Traditional QuEChERS clean-up of food and agricultural sample matrices for pesticide residue analysis relies on the dispersive solid phase extraction (dSPE) technique.
For analytical laboratories using dSPE workflows, the sample is shaken with dispersed SPE media to remove unwanted matrix components that negatively impact data quality. In this webinar, we will present a new technique that simplifies QuEChERS clean-up and enhances analytical performance when compared to traditional dSPE. ISOLUTE® cSPE for QuEChERS columns allow for a convenient, flow-through clean-up workflow for both AOAC and EN QuEChERS techniques. This new workflow eliminates several time-consuming processes, such as capping, shaking, de-capping, and sample transfer. In addition to labor reduction, the ISOLUTE® cSPE for QuEChERS process is more effective at removing unwanted matrix components. Compared to traditional dSPE, extracts processed using cSPE columns result in cleaner analytical baselines, making sample analysis easier, more accurate, and more reliable.

Vacuum and leak detection solutions are crucial elements in advanced industrial processes for the electrification of vehicles.
This webinar discusses the benefits of helium leak detection (HLD) for e-Vehicle manufacturing and offers real-world suggestions for improving the accuracy of the results and optimizing process flow.
Vehicle electrification provides additional challenges and opportunities for vacuum products related to energy storage, in addition to the conventional automobile applications’ vacuum needs for airbag integrity, HVAC component testing, power train production, and testing. E-vehicle battery technology requires a tightly sealed shell around the storage cells, and HLD is the only technology with the sensitivity and dynamic range capable of confirming the integrity of the battery enclosure for the life of the vehicle.
Join Sr Applications Engineer Bartly Carlson for this unique perspective on using HLD in E-vehicle manufacturing and test applications.

Agilent Technologies: Leak Detection for E-Vehicle Applications

Leak Detection for E-Vehicle Applications

The benefits of helium leak detection (HLD) for e-Vehicle manufacturing and offers real-world suggestions for improving the accuracy of the results.

Method TO-15A, for the monitoring of air toxics, was released in 2020 and lowers the required method detection limit for all compounds covered by the method to 20 ppt.
This new, lower detection limit level challenges every aspect of the sampling and analysis process, especially blank levels. Background generated by instrumentation and sampling equipment has always been monitored for air toxic analysis, but these extremely low detection limits enhance the associated demands on the analyst.

Join this webinar to explore the utility of hydrogen in chemical research, its associated risks, and a safer laboratory solution: H-Genie® Lite. This innovative, compact hydrogen generator employs unique patented cell technology to convert water into high-purity hydrogen gas, reaching pressures up to 50 bar (725 psi). As an ideal replacement for conventional hydrogen cylinders, it not only boosts lab safety but is also perfect for filling autoclaves and pressured containers.
Subsequently, we will delve into metal-catalyzed hydrogenation reactions. Heterogeneous catalysts like Pd/C are commonly employed for nitro group reductions and hydrogenation of carbon-carbon and carbon-heteroatom double bonds. These catalysts also aid in O- and N- deprotection, yielding respective alcohols or amines, and in asymmetric hydrogenation reactions.
We’ll discuss the core principles of hydrogenation, featuring both heterogeneous and homogeneous catalysts, and highlight their significance in industrial applications. H-Genie® Lite seamlessly integrates with both batch and continuous flow chemistry hydrogenation processes.

Per- and polyfluoroalkyl substances (PFAS), an emerging class of toxic anthropogenic chemicals persistent in the environment, are currently regulated at the low part-per-trillion level worldwide in drinking water. Quantification and screening of these compounds currently rely primarily on liquid chromatography mass spectrometry (LC-MS).
To better meet the regulatory demands of rapid screening of these chemicals, the hyphenating of solid phase microextraction (SPME) with direct analysis in real time (DART) will be demonstrated. PFAS analysis screened rapidly by DART on the Bruker EVOQ triple quadrupole using LC free workflows demonstrates a significant increase in productivity whilst also presenting a more economical and a greener solution for the lab.
Join us live for the real-time analysis of PFAS with SPME-DART-MS and discover the power of our cutting-edge instrumentation and technologies.

Ongoing helium srtages can cause unpredictability for gas chromatographers. This is impacting lab managers who have now to manage sensible price fluctuations and potential delivery interruptions with helium carrier gas for GC analyses.
There might be different approaches to address the consequences of helium shortage and increased costs. In many cases switching to alternative gas can be a suitable solution but there are situations where you really need to use helium as your carrier gas. Regulated methods, SOPs, or high-sensitivity GC/MS methods may require the use of helium. In these cases, helium conservation should be pursued.
<h4>In this webinar you will learn how to:</h4>
<ul>
<li>Take advantage of Gas Saver.
</li>
<li>Utilize the optional programmable helium conservation module for your Agilent GC.
</li>
<li>Check and maintain your helium infrastructure to prevent leaks.
