该文献描述了一种高效液相色谱(HPLC)方法，用于测定聚酰胺6、己内酰胺和重排产物在水中的混合物的样品中0.01质量%以上的己内酰胺环状低聚物和5mg/kg以上的己内酰胺直链低聚物的浓度，包括己内酰胺六聚物(n=6)。第二种明显更快的HPLC方法用于测定己内酰胺及其环状二聚体，基于与第一种方法相同的原理并使用相同的设备。

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 determination of caprolactam and its cyclic dimer, based on the same principle and using the same equipment as the first method.
