Abstract:
Standard methods for measurement of per- and polyfluoroalkyl (PFAS) utilize liquid chromatography mass spectrometry (LC-MSMS). This technique is for specific PFAS, very sensitive, and highly accurate. However, it is expensive and time-consuming. Given the diverse range PFAS (>5000), preclude the use of LC-MSMS as a practical first option for analysis. Therefore, there is an urgent need for a universal, rapid, and cost-effective PFAS screening tool. We propose the development of pyrolysis-gas chromatography mass spectroscopy tool as a PFAS screening tool. Analysis for organic fluorine through py-GCMS can serve as a reliable marker for fluorinated organic compounds present in environmental samples.
