03 Oct 2025

feature EVAR4289
  • 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. In addition, you can register and directly compare analyte lists and matrices across PFAS analysis methods here or visit www.restek.com/PFAS to explore our technical resources for PFAS analysis.

Analyte List for U.S. EPA Method 8327 for PFAS Analysis

PFAS acronyms, compound names, and CAS numbers vary across methods and guidelines, and they also depend on compound form (e.g., neutral vs. salt). The following list uses standardized terminology to allow easy comparison across the methods and guidelines in our comprehensive guide. Please refer to U.S. EPA Method 8327 for method-specific nomenclature.
