Abstract
ISO 11337:2010 specifies a method for determining epsilon‑caprolactam and omega‑laurolactam in polyamides by gas chromatography. It is suitable particularly for the determination of epsilon‑caprolactam in polyamide 6 and omega‑laurolactam in polyamide 12. Bearing in mind that gas chromatography offers a wide range of possible conditions, the method specified is that shown to have been suitable in practice.
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.
