Analysis of Volatile PFAS in Water Using Head-Space Solid Phase Microextraction-Gas Chromatography/Mass Spectrometry (HS-SPME GC/MS)
There are several established PFAS standard methods that specify the use of Liquid Chromatography/Mass Spectrometry (LC/MS); however, LC/MS is unable to analyze all PFAS compounds for various reasons. With its ability to analyze these compounds in complex matrices and simplified sample prep, Head-Space Solid Phase Microextraction GC/MS is pivotal as a complementary technique to LC/MS. Download this application for details on a method using GCMS for PFAS identification and quantitation.
