Find out more about the ISO 21675 standard
ISO 21675:2019 specifies a method for the determination of per- and polyfluoroalkylated substances (PFAS) in water, including drinking water, groundwater and surface water. It uses liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) to detect and quantify these contaminants. This method is essential for assessing water quality and monitoring persistent pollutants.
