T/CSTM 00745-2022 Plant oil and determination of benzo(a)pyrene by supercritical fluid chromatography with on-line purification and reversed-phase high-performance liquid chromatography
Basic Information
Scope
Scope: This document specifies a method for determining benzo(a)pyrene in vegetable oil using supercritical fluid chromatography online purification and reversed-phase high-performance liquid chromatography. This document is applicable to the determination of benzo(a)pyrene in vegetable oil with a mass fraction of 0.5μg/kg to 50μg/kg. Note: The scope specified in this document has been verified through inter-laboratory tests. By changing the sample quantity, the measurement range may be expanded. Once the measurement range is extended, the laboratory should confirm it by experimental means.
