本文件规定了一种在GC/MS分析之前，基于酸催化的酯裂解和裂解（游离）分析物与苯基硼酸（PBA）的衍生化，在一次测定中同时测定2-MCPD酯（结合2-MCPD）、3-MCPD酯（结合3-MCPD）和缩水甘油酯（结合缩水甘油）的程序。
本文件适用于固体和液体脂肪和油。对于所有三种分析物，定量限（LOQ）为0.1mg/kg，检测限（LOD）为0.03mg/kg。

This document specifies a procedure for the simultaneous determination of 2-MCPD esters (bound 2-MCPD), 3‐MCPD esters (bound 3‐MCPD) and glycidyl esters (bound glycidol) in a single assay, based on acid catalysed ester cleavage and derivatization of cleaved (free) analytes with phenylboronic acid (PBA) prior to GC/MS analysis.
This document is applicable to solid and liquid fats and oils. For all three analytes the limit of quantification (LOQ) is 0,1 mg/kg and the limit of detection (LOD) is 0,03 mg/kg.
