Scope

This standard specifies the method for the determination of perfluorooctane
sulfonate (PFOS) and perfluorooctanoic acid (PFOAA) in food contact materials
and products by tandem mass spectrometry.
This standard is applicable to the determination of PFOS and PFOA in food
contact materials and products such as carton, rubber, polyethylene, plastics,
resin, non-stick pan coating and so on.
2 Principle
PFOS and PFOA in food contact materials and products were extracted by
methanol to accelerate solvent extraction, purified by weak anion exchange
solid-phase extraction column, separated by liquid chromatography, ionized by
electrospray ionization, determined by multi-reaction monitoring mode and
quantified by Isotopic internal standard quantity.
