GB 5009.253-2016 National Food Safety Standard Determination of Perfluorooctane Sulfonate (PFOS) and Perfluorooctanoic Acid (PFOA) in Animal-derived Food (English Version)
1 Scope
This standard specifies the isotope dilution liquid chromatography-tandem mass spectrum method for the determination of perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) in animal-derived food.
This standard is applicable to the determination of PFOS and PFOA in animal-derived food.
2 Principle
Extract the PFOS and PFOA from the specimen by using acetonitrile, purify the matters with dispersive solid-phase extraction, determine them with liquid chromatography-tandem mass spectrometry, and quantify them with internal standard method.
3 Reagents and Materials
Unless otherwise specified, analytically-pure reagents and Grade I water (defined in GB/T 6682) are adopted for the purposes of this method.
