标准摘要
[中文适用范围]： 本文件规定了通过气相色谱法测定聚酰胺中ε-己内酰胺和ω-月桂内酰胺的方法。 它特别适用于测定聚酰胺 6 中的 ε-己内酰胺和聚酰胺 12 中的 ω-月桂内酰胺。 指定了基本方法的两种变体。 —方法A是用沸腾的甲醇提取方法，将提取物注入气相色谱仪。 —方法B是使用溶剂的方法，将溶液注入气相色谱仪。 [外文原描述]： This document specifies a method for determining ε‑caprolactam and ω‑laurolactam in polyamides by gas chromatography. It is applicable particularly to the determination of ε‑caprolactam in polyamide 6 and ω‑laurolactam in polyamide 12. Two variants of the basic method are specified. — Method A is an extraction method with boiling methanol, and the extract is injected into a gas chromatograph. — Method B is a method using a solvent, and the solution is injected into a gas chromatograph.
