A Methods-Based Reference to Lab Supplies for PFAS Testing<\/h2>\n\n\n\n

PFAS \u201cforever chemicals\u201d are ubiquitous in the environment, but they are also commonly found in lab supplies and even in instruments, so it is essential to prevent background sources from contaminating samples. PFAS can also be \u201csticky\u201d and adhere to certain materials that are regularly used in sampling and analysis (e.g., glass containers or pipettes), so everything in the sample flow path must be considered for its ability to either contribute background PFAS or to retain PFAS that is present in samples.<\/p>\n\n\n\n

The risk of PFAS contamination or retention can make choosing the right lab supplies for PFAS analysis difficult, but it is also challenging because many methods are available, and they use different sample preparation and analysis products. Selecting suitable lab supplies is even harder when you want to measure trace levels of PFAS that are not listed in current government methods or guidelines, such as short- and ultrashort-chain PFAS. <\/p>\n\n\n\n

Finding suitable products can be simplified using the product guide tables below, which detail the lab supplies for PFAS analysis that are appropriate for widely accepted test methods from around the world, including U.S. agencies (CDC, EPA, FDA, and USDA); European agencies (DIN); and international standards (ASTM and ISO). After selecting method-appropriate products, be sure to evaluate your system and supplies to ensure they are free of target analytes and qualified for PFAS analysis at the levels required by the method. <\/p>\n\n\n\n

Restek is proud to support PFAS testing labs with clean, high-quality lab supplies for PFAS testing and expert technical support for the analysis of legacy, alternative, and ultrashort-chain PFAS across a wide range of global testing standards. You can register and directly compare analyte lists and matrices across methods here<\/a> or visit www.restek.com\/PFAS<\/a> to explore our technical resources for PFAS analysis.<\/p>\n\n\n\n
