This International Standard specifies a method for determining e-caprolactam and ω-laurolactam in polyamides by gas chromatography. It is suitable particularly for the determination of e-caprolactam in polyamide 6 and ω- 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 methods are specified in this international standard. - Method A is an extraction method with boiling methanol and the extracts are injected into a gas chromatograph; - Method B is a method using a solvent and the solution is directly injected into a gas chromatograph.
