- Sample Matrix: surface water, groundwater, and wastewater
- Sample Preparation: method refers to SW-846 Methods 3500 and 3600
- Detection Technique: LC-MS/MS
Per- and Polyfluorinated Alkyl Substances (PFAS) by Liquid Chromatography/Tandem Mass Spectrometry (LC-MS/MS)
U.S. EPA Method 8327 is used for the analysis of 24 PFAS in surface water, groundwater, and wastewater. It refers to SW-846 Methods 3500 and 3600 for details on an appropriate sample preparation procedure (e.g., solvent dilution or extraction), and provides example conditions for LC-MS/MS analysis on a C18 column. Method 8327 is part of the SW-846 compendium and notes that SW-846 methods are intended to be guidance methods that contain general information on how to perform an analytical procedure or technique, which a laboratory can use as a basic starting point for generating its own detailed standard operating procedure (SOP), either for its own general use or for a specific project application. The full analyte list and recommended products for PFAS analysis in surface water, groundwater, or wastewater by Method 8327 are provided below.
