ELLINGTON, J. J., J. W. WASHINGTON, J. J. EVANS, T. JENKINS, AND S. Hafner. Method Development for the Determination of Fluorotelomer Alcohols in Soils by Gas Chromatography Mass Spectrometry. Presented at PFAA (Perfluorinated Alkyl Acids) Days II Workshop, Research Triangle Park, NC, June 03 - 05, 2008.
Impact/Purpose:
Presentation at the Perfluorinated Alkyl Acids Conference in June 2008.
Description:
Fluorotelomer alcohols (FTOHs) have been widely studied as precursors to perfluorocarboxylates, e.g. 8:2 FTOH degrades to perfluorooctanoic acid (PFOA). This presentation describes an analytical method for the extraction and analysis of 6:2, 8:2, and 10:2 FTOHs. Gas chromatograph/chemical ionization-mass spectrometry (GC/CI-MS) was used for sensitive determination of the fluortelomer alcohols. The best selectivity and sensitivity was observed when the detector was operated in the positive mode (GC/PCI-MS).
