PFAS
Stay current with evolving PFAS regulations
Per- and Polyfluoroalkyl Substances (PFAS) are widely used in industrial and consumer products. These man-made chemicals migrate to water, air, soil, human and animal tissue, and food products and due to their chemical nature, they remain and accumulate in the environment. They have increasingly become of concern for health reasons, therefore leading to calls for more stringent regulations and monitoring. To that end, environmental testing laboratories are being asked to analyze for more species of PFAS at lower concentrations.

Expanding PFAS PT and CRM portfolio for you
Waters ERA continues to expand our PFAS product line and study availability to keep pace with your needs and the evolving analytical methods. ERA’s newest addition to our PFAS product line will assist your laboratory in achieving accreditation to EPA Method 1633 (Draft), ASTM Method D8421-21 (Draft) and SW-846 Method 8327. With 44 PFAS analytes, your lab can add accreditation, demonstrate analyst competency and document your commitment to quality for these new methods. See analyte list below
