Description

General description

Heptadecafluorooctanesulfonic acid potassium salt (PFOSK) is a salt derivative of heptadecafluorooctanesulfonic acid (PFOS) that is classified under the family of poly/perfluoroalkyl alkyl substances (PFASs) primarily used as hydrocarbon-based flame retardants.

Application

PFOSK can be used to prepare PFOS which may be utilized as an analytical reference standard for the determination of PFOS in:
• Groundwater samples by high performance liquid chromatography-electrospray tandem mass spectrometry (HPLC-ESI-MS/MS).
• Water samples from river and industrial effluents by solid phase extraction (SPE) and HPLC coupled to ion trap ESI-MS with multiple reaction monitoring (MRM) detection.
• Aqueous solutions by ultra-performance liquid chromatography coupled to triple quadrupole mass spectrometer (UPLC-MS/MS) equipped with ESI source and MRM detection.
• Tap water samples by SPE and LC-ESI-MS with selected ion monitoring (SIM) mode of quantitation.
