Plastics. Determination of caprolactam and its cyclic and linear oligomers by HPLC1 Scope This document describes a high performance liquid chromatography (HPLC) method for determining the concentrations of cyclic oligomers of caprolactam, from 0,01 % by mass upwards, and linear oligomers of caprolactam, from 5 mg kg upwards, both up to and including the hexamer of caprolactam (n = 6), in samples of polyamide 6, caprolactam and mixtures of rearrangement products in water. A second, significantly faster, HPLC method is included for
