Ultra-Trace Quantification of Per- and Polyfluoroalkyl Substances (PFAS) in Drinking Water
Author(s)Agilent Technologies, Inc.
The US EPA has released interim health advisory limits (HALs) of 4 and 20 pg/L in drinking water for the PFAS perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS), respectively. This application note addresses PFAS testing at these challenging new levels in aqueous samples using optimized solid-phase sample extraction and LC/MS/MS analysis with an Agilent 1290 Infinity II liquid chromatography (LC) system coupled to an Agilent 6495C triple quadrupole (TQ) mass spectrometer.
