The analysis of PFAS by EPA 1633A and ASTM D8421 is part of the U.S. EPA’s Methods Update Rule (MUR) Rule 22. The action will promulgate EPA into 40 CFR Part 136. Also part of this action, PFAS method ASTM D8421 is proposed to be codified.
Merit Laboratories offers several analytical options for PFAS. Analytical methods performed by Merit Laboratories include EPA 533, EPA 537 Rev. 1.1, EPA 537.1 ASTM D7979-19 with Isotopic Dilution, and ASTM D7968-17. The following summary will help guide you through selecting the most appropriate PFAS method for your project. EPA 537 Rev. 1.1: This is a drinking water method for 14 PFAS compounds using Solid Phase Extraction and Liquid Chromatography/Tandem Mass Spectrometry (LC/MS/MS).
The U.S. Environmental Protection Agency (EPA) finally validated EPA SW-846 Method 8327 for the analysis of PFAS using LC/MS/MS instrumentation for non-potable water. Sample matrices for EPA 8327 include surface water, groundwater water, and wastewater. The method evaluated 24 PFAS compounds.
