D8421 - Test Method for Determination of Per- and Polyfluoroalkyl Substances (PFAS) in Aqueous Matrices by Co-solvation followed by Liquid Chromatography Tandem Mass Spectrometry (LC/MS/MS)

The precision of this research report is based on an interlaboratory study of D8421, Test Method for Determination of Per- and Polyfluoroalkyl Substances (PFAS) in Aqueous Matrices by Co-solvation followed by Liquid Chromatography Tandem Mass Spectrometry (LC/MS/MS), conducted in 2024. 21 laboratories reported data for this study. Each of the laboratories were asked to report 2 replicates test results on a total of 68 materials. Every “test result” represents an individual determination. Practice ASTM E691 was followed for the design of the study and analysis of the data; the details are given in ASTM Research Report No D19-2006.
