DESCRIPTION

EN ISO 11337


EN ISO 11337 Plastics - Polyamides - Determination of e-caprolactam and wlaurolactam by gas chromatography (ISO 11337:2010) - 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: 1.Method A is an extraction method with boiling methanol, and the extract is injected into a gas chromatograph. 2.Method B is a method using a solvent, and the solution is injected into a gas chromatograph.
