HFIP Quantification
Hexafluoroisopropanol (HFIP), also known as hexafluoro-2-propanol, is a fluorinated alcohol commonly used in processing of polyethylene terephthalate, polyacrylonitriles, some polyketones, and polyamides. It is a fairly toxic material, causing several eye damage and respiratory problems. Consequently, manufacturers who use HFIP need to measure how much residual HFIP remains in their processed goods, particularly if the goods are being used for biomedical purposes.
HFIP can be quantified with solvent extraction followed by gas chromatography-mass spectroscopy. This method can be used to detect HFIP concentrations down to approximately 100 ppb. The technique requires a reliable extraction methodology, and a GC-MS protocol that will provide separation of HFIP from any other co-eluting species that may be extracted from the test sample.
