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)
What is ISO 21675 - Liquid chromatography-tandem mass spectrometry about?
ISO 21675 discusses water quality with a focus on the determination of perfluoroalkyl and polyfluoroalkyl substances (PFAS) in water.
ISO 21675 specifies a method for the determination of selected perfluoroalkyl and polyfluoroalkyl substances (PFAS) in non‑filtrated waters, for example, drinking water, natural water (fresh water and seawater), and wastewater containing less than 2 g/l solid particulate material (SPM) using liquid chromatography-tandem mass spectrometry (LC‑MS/MS).
The lower application range of the method given in ISO 21675 can vary depending on the sensitivity of the equipment used and the matrix of the sample. For most compounds to which this document applies ≥0.2 ng/l as the limit of quantification can be achieved. Actual levels can depend on the blank levels realized by the individual laboratory.
