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.
