T/ZSA 114-2022 Plant oil and determination of benzo(a)pyrene using supercritical fluid chromatography online purification and reversed-phase high-performance liquid chromatography
Basic Information
Scope
Scope: This document specifies the method for determining benzo[a]pyrene in vegetable oil using on-line purification with supercritical fluid chromatography and reverse-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. For vegetable oil samples with benzo[a]pyrene content exceeding 50μg/kg, they can be diluted and then tested according to this document.
