This document specifies a method for determining e-caprolactam and w-laurolactam in polyamides by gas chromatography. It is applicable particularly to the determination of e-caprolactam in polyamide 6 and w-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.
