Plastics - Polyamides - Determination of e-caprolactam and w-laurolactam by gas chromatography (ISO 11337:2004)

ISO 11337:2004 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.
Method A is suitable for the determination of epsilon-caprolactam and method B for epsilon-caprolactam and omega-laurolactam.

Kunststoffe - Polyamide - Gaschromatographische Bestimmung von e-Caprolactam und w-laurolactam (ISO 11337:2004)

Anwendungsbereich
Die vorliegende Internationale Norm legt ein gaschromatographisches Verfahren zur Bestimmung des e-Caprolactamgehaltes und des w-Laurolactamgehaltes in Polyamiden fest. Es ist besonders zur Bestimmung von e-Caprolactam in Polyamid 6 (Nylon) und von w-Laurolactam in Polyamid 12 geeignet. Unter Berücksichtigung der Tatsache, dass die Gaschromatographie einen ausgedehnten Bereich von Möglichkei-ten bietet, hat sich das festgelegte Verfahren in der Praxis als geeignet erwiesen.
In dieser Internationalen Norm werden zwei Verfahren beschrieben:
¾ Verfahren A ist ein Extraktionsverfahren unter Anwendung von siedendem Methanol, bei dem die Extrakte in einen Gaschromatograph injiziert werden;
¾ Verfahren B ist ein Verfahren unter Anwendung eines Lösungsmittels, bei dem die Lösung direkt in einen Gaschromatograph injiziert wird.

Plastiques - Polyamides - Détermination du e-caprolactame et du w-laurolactam par chromatographie en phase gazeuse (ISO 11337:2004)

L'ISO 11337:2004 spécifie une méthode par chromatographie en phase gazeuse pour le dosage de l'epsilon-caprolactame et de l'omega-laurolactame dans les polyamides. Elle convient particulièrement au dosage de l'epsilon-caprolactame dans le polyamide 6 et de l'omega-laurolactame dans le polyamide 12. Compte tenu du fait que la chromatographie en phase gazeuse présente un large éventail de conditions possibles, la méthode spécifiée est celle qui a fait ses preuves dans la pratique.
Deux variantes de la méthode de base sont spécifiées:
Méthode A, méthode par extraction au méthanol en ébullition, où l'extrait est injecté dans un chromatographe en phase gazeuse.Méthode B, méthode utilisant un solvant, où la solution est injectée dans un chromatographe en phase gazeuse.
La méthode A est appropriée pour la détermination de l'epsilon-caprolactame et la méthode B pour celle de l'epsilon-caprolactame et de l'omega-laurolactame.
