Two PFAS compounds, PFOA and PFOS have been named as hazardous substances under CERCLA allowing EPA to enforce monitoring and cleanup of contaminated sites. EPA has proposed including these and additional PFAS to RCRA regulations. The most used technique for PFAS analysis are Tandem Liquid Chromatography Mass Spectrometry or LC-MS/MS. Other approaches, such as single quadrupole LCMS, High Resolution LCMS, or GCMS may be used depending on the objectives of the analysis.
Adsorbable Organic Fluorine (AOF) is a screening method designed to detect additional PFAS compounds not captured by chromatographic methods. Fluorinated pesticides and pharmaceuticals may also be detected.
Shimadzu offers a variety of analytical solutions for PFAS testing in environmental samples in accordance with the following standardized methods.
