Water quality. Determination of perfluorooctanesulfonate (PFOS) and perfluorooctanoate (PFOA). Method for unfiltered samples using solid phase extraction and liquid chromatography/mass spectrometry Ingestion-build-224916 Test Suites and Software Applications1 Scope This International Standard specifies a method for the determination of the linear isomers of perfluorooctanesulfonate (PFOS) and perfluorooctanoate (PFOA) in unfiltered samples of drinking water, ground water and surface water (fresh water and sea water) using high performance liquid chromatography tandem mass spectrometry (HPLC MS MS). Other isomers may be reported separately as non linear isomers and qualified as such. The analytes
