Food related products and daily consumer goods testing

This standard specifies the liquid chromatography-tandem mass spectrometry method for the determination of perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) in food contact materials and products. This standard is applicable to the determination of PFOS and PFOA in food contact materials and products such as cardboard boxes, rubber, polyethylene, plastics, resins, and non stick pot coatings. 2 Principle The PFOS and PFOA in food contact materials and products use methanol as the extraction solvent, accelerated solvent extraction, weak anion exchange solid phase extraction column purification, liquid chromatography separation, electrospray ion source (ESI) ionization, multi reaction monitoring mode (MRM) detection, and quantitative analysis by the same position internal standard method
