GB 31604.35-2016 National Food Safety Standard - Food Contact Materials and Articles -Determination of Perfluorooctane Sulfonate (PFOS) and Perfluorooctanoate (PFOA) (English Version)
1 Scope
This standard specifies the determination method for perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA) in food contact materials and articles through liquid chromatography-tandem mass spectrometry.
This standard is applicable to determination of PFOS and PFOA in such food contact materials and articles as carton, rubber, polyethylene, plastic, resin, non-stick pan coating, etc.
2 Principle
PFOS and PFOA in food contact materials and articles are extracted through accelerated solvent extraction method by taking methanol as extraction solvent, purified by weak anion-exchange solid-phase extraction column, separated by liquid chromatography, ionized by electrospray ionization source (ESI), detected in multiple reaction monitoring mode (MRM) and quantatively determined by isotope internal standard method.
