Single-Laboratory Validation Study of PFAS by Isotope Dilution LC-MS/MS
This report presents the findings of a single-laboratory validation study (SLVS) of an analytical method for the preparation and analysis of per- and polyfluoroalkyl substances (PFAS) in environmental matrices. Conducted as a joint effort by the U.S. Department of Defense (DoD) and the Environmental Protection Agency (EPA), the study was designed to provide data on the accuracy and precision of the method in aqueous matrices (wastewater, surface waters, groundwaters, landfill leachate), solids (soil, sediment, biosolids), and fish and clam tissues. The laboratory standard operating procedure (SOP) used and the results of the study were the basis of the EPA's draft Office of Water Method 1633: Analysis of Per- and Polyfluoroalkyl Substances (PFAS) in Aqueous, Solid, Biosolids, and Tissue Samples by LC-MS/MS (EPA Method 1633).
