As regulations evolve and PFAS analysis expands beyond traditional water testing, laboratories are adapting to new challenges across environmental, food and industrial sectors.Laboratories around the world are facing a new reality for <a target="_blank" rel="noopener noreferrer" href="https://www.thermofisher.com/content/lifetech/global/en/home/industrial/environmental/environmental-contaminant-analysis/emerging-contaminants/pfas-testing.html">PFAS analysis</a>. Expanding regulations, growing lists of compounds of concern, and increasing demand for analysis across environmental, food and industrial sectors mean many laboratories are being asked to do more than ever before.While these changes are global, Europe continues to play an important role in shaping the regulatory landscape. Since January 2026, EU Member States have been required to monitor PFAS levels in drinking water and ensure they remain within EU limits. Regulatory attention is also extending beyond drinking water to surface and groundwater, soil, packaging and industrial emissions, as outlined in the <a target="_blank" rel="noopener noreferrer" href="https://environment.ec.europa.eu/topics/chemicals/pfas-pollution_en">European Commission’s overview of PFAS pollution and EU action</a>.Although requirements differ by region, the direction is clear: laboratories are facing analytical questions involving more compounds and a wider range of matrices. For scientists looking to keep pace, our <a target="_blank" rel="noopener noreferrer" href="https://gateway.on24.com/wcc/eh/4080611/category/139628/pfas-testing?partnerref=E.25CMD.EL102.26305.01">PFAS resources</a> bring together webinars, application notes and expert insights across environmental, food and industrial testing.<h5>PFAS analysis is no longer defined by a single matrix or a single workflow.</h5><h3>PFAS analysis is expanding</h3>For many laboratories, PFAS analysis began with drinking water. Today, the scope has expanded considerably.Laboratories are increasingly working across drinking water, groundwater, surface water and wastewater, as well as food and food contact materials, cosmetics and personal care products, environmental samples, and industrial and consumer products.Each matrix presents different analytical challenges. Water analysis can require trace-level quantification, while complex food and consumer-product matrices may require different sample preparation or broader screening approaches. Techniques such as total organic fluorine (TOF) analysis can also provide a complementary perspective to targeted PFAS measurements.This diversity means there is no single analytical approach that answers every PFAS question.<h5>As PFAS analysis expands beyond drinking water, laboratories need approaches that can adapt to diverse sample types and evolving regulatory expectations.</h5><h3>Learning from the scientific community</h3>As laboratories respond to these changing analytical demands, many are exploring new approaches to longstanding challenges such as sample preparation.One example comes from Severn Trent Laboratories (Bridgend, UK), which implemented a PFAS workflow using Dispersive Liquid–Liquid Micro Extraction (DLLME). The approach provides an alternative to traditional solid phase extraction and can help reduce sample handling and solvent consumption.Laboratories interested in the approach can explore more information on <a target="_blank" rel="noopener noreferrer" href="https://www.thermofisher.com/content/lifetech/global/en/home/industrial/environmental/efox-analytical-solutions-platform/workflows.html">DLLME and PFAS workflows</a>.<h3>Watch the webinar</h3><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Thermo_Fisher_Scientific_PFAS_Analysis_Beyond_Water_Meeting_the_Challenges_of_Environmental_Food_and_Industrial_Testing_2aeaa52248.jpg" alt="Thermo Fisher Scientific: PFAS Analysis Beyond Water: Meeting the Challenges of Environmental, Food and Industrial Testing" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Thermo_Fisher_Scientific_PFAS_Analysis_Beyond_Water_Meeting_the_Challenges_of_Environmental_Food_and_Industrial_Testing_2aeaa52248.jpg 245w," sizes="100vw" width="800" height="347"><h4>Severn Trent / PFAS webinar</h4>EFOX approach for environmental workflows: PFAS &amp; emerging contaminantsHear more about this approach and explore wider developments in PFAS and emerging contaminant analysis.<blockquote><h4><a target="_blank" rel="noopener noreferrer" href="https://labrulez.com/en-us/all/webinar/6542">Watch on demand</a></h4></blockquote><h3>The changing PFAS landscape</h3>The changing analytical landscape extends well beyond sample preparation. Laboratories are simultaneously navigating evolving regulations, growing lists of compounds of interest, greater scrutiny of food and industrial materials, and increasing interest in broader screening approaches.Europe illustrates how these trends are converging. Alongside drinking-water requirements, EU action extends to industrial emissions and food-contact packaging. The Industrial Emissions Directive imposes stricter monitoring of PFAS emissions, with reporting requirements for PFOA, PFHxS and their salts from 2028. From August 2026, EU rules also ban food-contact packaging containing PFAS above specified concentration limits, as detailed in the <a target="_blank" rel="noopener noreferrer" href="https://environment.ec.europa.eu/topics/chemicals/pfas-pollution_en">European Commission’s overview of PFAS pollution and EU action</a>.Changes are also underway for Europe’s surface water and groundwater. Updated pollutant lists that entered into force in May 2026 include certain PFAS, including TFA, among substances to be monitored more closely and subject to stricter controls under the <a target="_blank" rel="noopener noreferrer" href="https://environment.ec.europa.eu/topics/water/water-framework-directive_en">EU Water Framework Directive.</a>The European picture also demonstrates why PFAS is no longer solely an environmental-water issue. PFAS have been widely used in products including food packaging, textiles, lubricants and batteries, while industrial activities that produce or use PFAS can contribute to environmental releases.Globally, regulatory requirements vary, but the analytical challenge is similar: laboratories need the flexibility to respond as both the compounds of interest and the matrices under investigation change.<h3>PFAS analysis across different sample types</h3>Different matrices raise different analytical questions—from selecting an appropriate sample preparation strategy to deciding between targeted quantification and broader screening approaches.<h4>Environmental and water PFAS analysis</h4><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Thermo_Fisher_Scientific_PFAS_Analysis_Beyond_Water_Meeting_the_Challenges_of_Environmental_Food_and_Industrial_Testing_2_3ef68ae44e.jpg" alt="Thermo Fisher Scientific: PFAS Analysis Beyond Water: Meeting the Challenges of Environmental, Food and Industrial Testing" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Thermo_Fisher_Scientific_PFAS_Analysis_Beyond_Water_Meeting_the_Challenges_of_Environmental_Food_and_Industrial_Testing_2_3ef68ae44e.jpg 245w," sizes="100vw" width="768" height="439">Explore analytical approaches for drinking water, groundwater, surface water and wastewater, including automated sample preparation and multi-matrix PFAS quantification.<ul><li><a target="_blank" rel="noopener noreferrer" href="https://www.thermofisher.com/content/lifetech/global/en/home/industrial/environmental/efox-analytical-solutions-platform/workflows.html">Automated DLLME for environmental PFAS analysis</a></li><li>Resource: <a target="_blank" rel="noopener noreferrer" href="https://labrulez.com/pdf/ab_004180_efs_orbitrap_exploris_efox_ab004180_em_en_932cc99eb4.pdf">Quantification of 61 PFAS across drinking water, groundwater, surface water and wastewater</a></li></ul><h4>Food and food contact materials PFAS analysis</h4><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Thermo_Fisher_Scientific_PFAS_Analysis_Beyond_Water_Meeting_the_Challenges_of_Environmental_Food_and_Industrial_Testing_3_eb783dd0d3.jpg" alt="Thermo Fisher Scientific: PFAS Analysis Beyond Water: Meeting the Challenges of Environmental, Food and Industrial Testing" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Thermo_Fisher_Scientific_PFAS_Analysis_Beyond_Water_Meeting_the_Challenges_of_Environmental_Food_and_Industrial_Testing_3_eb783dd0d3.jpg 245w," sizes="100vw" width="768" height="433">Explore PFAS analysis in food and food-contact materials, including total organic fluorine (TOF) screening and evolving approaches to investigating fluorinated compounds in packaging.<ul><li><a target="_blank" rel="noopener noreferrer" href="https://labrulez.com/en-us/all/article/5894">Enhancing PFAS analysis in food contact materials using combustion ion chromatography</a></li></ul><h4>Cosmetics / industrial PFAS analysis</h4><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Thermo_Fisher_Scientific_PFAS_Analysis_Beyond_Water_Meeting_the_Challenges_of_Environmental_Food_and_Industrial_Testing_4_99a5bfea7e.jpg" alt="Thermo Fisher Scientific: PFAS Analysis Beyond Water: Meeting the Challenges of Environmental, Food and Industrial Testing" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Thermo_Fisher_Scientific_PFAS_Analysis_Beyond_Water_Meeting_the_Challenges_of_Environmental_Food_and_Industrial_Testing_4_99a5bfea7e.jpg 245w," sizes="100vw" width="768" height="432">Explore approaches for investigating PFAS and total organic fluorine in complex matrices such as cosmetics and other consumer or industrial materials.<ul><li><a target="_blank" rel="noopener noreferrer" href="https://labrulez.com/pdf/an_004403_ic_cic_industrial_an004403_na_en_3c2419b88b.pdf">Total PFAS content in cosmetics using combustion ion chromatography</a></li></ul><blockquote><h4><a target="_blank" rel="noopener noreferrer" href="https://gateway.on24.com/wcc/eh/4080611/category/139628/pfas-testing?partnerref=E.25CMD.EL102.26305.01">Explore all PFAS resources</a></h4></blockquote><h3>Learn from experts</h3>As PFAS science and regulation continue to evolve, knowledge sharing across the scientific community is becoming increasingly valuable.<h4>Live from the Lab: Solutions for Environmental and Food Contaminant Analysis 2026</h4><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Thermo_Fisher_Scientific_PFAS_Analysis_Beyond_Water_Meeting_the_Challenges_of_Environmental_Food_and_Industrial_Testing_5_3afde1ec49.jpg" alt="Thermo Fisher Scientific -

PFAS Analysis Beyond Water: Meeting the Challenges of Environmental, Food and Industrial Testing

Wiley, a global leader in authoritative content and research intelligence, today announced the launch of its spectral analysis application programming interface (API) portfolio, providing users with a new, faster way to access its trusted spectral data, analytical algorithms, and predictive models—within their own workflows.Wiley has one of the most comprehensive and trusted collections of scientific reference databases in the world, relied upon as a gold standard for identifying unknown chemical compounds by laboratories, instrument vendors, and software platforms across pharmaceuticals, forensics, environmental science, chemicals, food, materials, and other fields. The new portfolio extends the data and tools into modern, API-driven environments—allowing users to integrate high-quality spectral intelligence directly into their own systems and workflows.As sample volumes grow and lab workflows become more automated and software-driven, identifying and verifying compounds quickly and reliably becomes even more critical. The new API portfolio meets that need directly, giving labs and platforms a faster way to complete the process, whether catching a quality issue on a production line or identifying an unknown compound in the field. The result is less manual effort, faster analysis, and more confidence in the answer.The launch builds on Wiley's mission to transform knowledge into actionable intelligence for corporate and academic researchers around the world."Speed matters when you're trying to identify an unknown substance; a delayed analysis can mean an assembly line sitting idle or a forensic lab holding up a case,” said Armughan Rafat, Wiley senior vice president and chief AI and data services officer. “We've spent decades building the reference data this industry trusts. Now, by making that spectral data and analytical intelligence available through APIs, we're setting the standard for how labs and vendors turn unknowns into answers faster and at scale."<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Wiley_API_spectral_search_5bfcb1dd9b.png" alt="Wiley: spectral analysis API" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Wiley_API_spectral_search_5bfcb1dd9b.png 128w," sizes="100vw" width="802" height="977"><h5>The API portfolio launches with four core capabilities:</h5><ul><li>Spectral Database Search API – Query Wiley’s comprehensive reference collections for rapid compound identification.</li><li>Spectrum-Structure Validation API – Confirm proposed chemical structures against experimental spectral data.</li><li>Compound Classification API – Classify unknown substances, including drugs, based on compound class.</li><li>Spectra Prediction API – Generate predicted spectra to support research, method development, and validation.</li></ul>Unlike fragmented in-house databases or instrument-specific solutions, these APIs offer a continuously curated, vendor-neutral foundation that supports multi-technique workflows, regulatory compliance, and cross-platform interoperability. As a result, laboratories can increase throughput, minimize downtime, and protect the value of the instrumentation and data in which they've already invested.<h4>Spectral Databases &amp; APIs</h4>Spectral databases contain unique molecular “fingerprints” of substances captured through analytical techniques such as infrared (IR), mass spectrometry (MS), nuclear magnetic resonance (NMR), and Raman spectroscopy. By comparing experimental spectra against validated reference data, researchers can accurately identify unknown compounds across a wide range of applications.An API is a common way for computer systems, from lab instruments to software platforms, to request information from one another and get an answer back automatically.<blockquote>For more information about the Wiley spectral analysis API portfolio, please <a target="_blank" rel="noopener noreferrer" href="https://sciencesolutions.wiley.com/spectral-analysis-apis/">visit this website</a></blockquote><h4>About Wiley</h4>Wiley is a global leader in authoritative content and research intelligence for the advancement of scientific discovery, innovation, and learning.

Watrex SYRINGE FILTERS

Syringe filters (filters for syringes) are a universal tool that ensures sample purity and prevents contamination of analytical instruments.

Syringe filters (filters for syringes) are a universal tool that ensures sample purity and prevents contamination of analytical instruments. They are single-use filters used for precise filtration of liquids before their application or analysis.Pore Size: Filters come in various pore sizes, ranging from 0.2 μm to 5 μm, depending on the required level of filtration. Smaller pores (e.g., 0.22 μm) are often used for sterilizing solutions, as they capture bacteria and other microorganisms.We offer syringe filters in the following sizes: 4 mm, 13 mm, 25 mm, and 30 mm, all available with pore sizes of 0.22 μm and 0.45 μm.Filter Material: Syringe filters are made from different materials that are compatible with various sample types. It is important to select the correct filter material based on the chemical composition of the sample.

This resin is optimal for the purification of, e.g. eukarytic cell feeds, which often containing these substances.For optimization, an initial screening is recommended with the different WorkBeads IMAC resins to identify the optimal combination of ligand and metal ion.Also available in pre-filled <a target="_blank" rel="noopener noreferrer" href="https://watrex.com/kategorie-produktu/bioprocessing-products/imac-chromatography/imac-columns/?utm_source=labrulez&amp;utm_medium=propagace&amp;utm_campaign=labrulez_produkty">GoBio™ Mini.</a><h4><a target="_blank" rel="noopener noreferrer" href="https://watrex.com/kategorie-produktu/bioprocessing-products/activated-resins/?utm_source=labrulez&amp;utm_medium=propagace&amp;utm_campaign=labrulez_produkty">Activated resins</a></h4>Pre-activated resin enables successful, convenient immobilization of ligands without the need for complex syntheses or special equipment. We have developed two different pre-activated resins where the bromohydrin active group reacts with thiol, amino and hydroxyl groups of the substance to be coupled. Two different resin porosities are available to facilitate optimized coupling of ligands of different sizes, or to optimize the prepared affinity resin for target molecules of different sizes.Resin for coupling your own ligands:<ul><li>Made from agarose, well established and well-known in the Biotechnology industry</li><li>Simple coupling procedures at ambient temperature</li><li>Stable at ambient temperature in aqueous solution and at neutral pH</li><li>Suitable for coupling of ligands containing sulphydryl, amino- or hydroxy group</li></ul>Available as <a target="_blank" rel="noopener noreferrer" href="https://watrex.com/kategorie-produktu/bioprocessing-products/activated-resins/activated-sorbents/?utm_source=labrulez&amp;utm_medium=propagace&amp;utm_campaign=labrulez_produkty">WorkBeadsTM sorbents</a> or in pre-filled <a target="_blank" rel="noopener noreferrer" href="https://watrex.com/kategorie-produktu/bioprocessing-products/activated-resins/activated-columns/?utm_source=labrulez&amp;utm_medium=propagace&amp;utm_campaign=labrulez_produkty">GoBio™ Mini</a>.For more information or a non-binding quote regarding BioWorks products, please contact us at watrex@watrex.com or visit our website <a target="_blank" rel="noopener noreferrer" href="https://watrex.com/?utm_source=labrulez&amp;utm_medium=propagace&amp;utm_campaign=labrulez_produkty">www.watrex.com</a>
