Water quality. Determination of perfluoroalkyl and polyfluoroalkyl substances (PFAS) in water. Method using solid phase extraction and liquid chromatography-tandem mass spectrometry (LC-MS/MS) algolia-search-ignore — Publish useful definitions for1 Scope This document specifies a method for the determination of selected perfluoroalkyl and polyfluoroalkyl substances (PFAS) in nonfiltrated waters, for example drinking water, natural water (fresh water and sea water) and waste water containing less than 2 g l solid particulate material (SPM) using liquid chromatography tandem mass spectrometry (LCMS MS). The compounds monitored by this method are typically the linear isomers. The group of
