Plastics - Polyamides - Determination of ε-caprolactam and ω-laurolactam by gas chromatography (ISO 11337:2023)
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.
