GB 5009.253-2016 Translated English of Chinese Standard. GB5009.253-2016: National Standard for Food Safety - Determination of Perfluorooctane Sulfonate (PFOS) and Perfluorooctanoic Acid (PFOA) in Animal-derived Food

Sampul Depan, 24 Jun 2018 - 11 halaman
This Standard specifies the method of isotope dilution liquid chromatography-tandem mass spectrometry in the determination of PFOS and PFOA in animal-derived food. This Standard shall be applicable to the determination of PFOS and PFOA in animal-derived food. Adopt acetonitrile to extract PFOS and PFOA from the sample. Start dispersive solid phase extraction and purification; adopt liquid chromatography-tandem mass spectrometer to determine PFOS and PFOA. Adopt the internal standard method to quantify the content.
