Plastics - Polyamides - Determination of e-caprolactam and w-laurolactam 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:
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.
Kunststoffe - Polyamide - Gaschromatographische Bestimmung von ε-Caprolactam und w-Laurolactam (ISO 11337:2010)
Diese Internationale Norm legt ein gaschromatographisches Verfahren zur Bestimmung des -Caprolactamgehaltes und des -Laurolactamgehaltes in Polyamiden fest. Es ist besonders zur Bestimmung von -Caprolactam in Polyamid 6 und von -Laurolactam in Polyamid 12 geeignet. Unter Berücksichtigung der Tatsache, dass die Gaschromatographie einen ausgedehnten Bereich von Möglichkeiten bietet, hat sich das festgelegte Verfahren in der Praxis als geeignet erwiesen.
Zwei Verfahren sind in dieser Internationalen Norm festgelegt:
Verfahren A ist ein Extraktionsverfahren unter Anwendung von siedendem Methanol, bei dem die Extrakte in einen Gaschromatographen injiziert werden;
Verfahren B ist ein Verfahren unter Anwendung eines Lösemittels, bei dem die Lösung direkt in einen Gaschromatographen injiziert wird.
Plastiques - Polyamides - Détermination du e-caprolactame et du w-laurolactame par chromatographie en phase gazeuse (ISO 11337:2010)
L'ISO 11337:2010 spécifie une méthode de dosage du epsilon-caprolactame et du omega-laurolactame dans les polyamides par chromatographie en phase gazeuse. Elle convient particulièrement au dosage du epsilon-caprolactame dans le polyamide 6 et du 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, par extraction au méthanol en ébullition, où les extraits sont injectés dans un chromatographe en phase gazeuse.
Méthode B, utilisant un solvant, où la solution est injectée directement dans un chromatographe en phase gazeuse.
Polimerni materiali - Poliamidi - Določanje e-kaprolaktama in w-laurolaktama s plinsko kromatografijo (ISO 11337:2010)
Ta mednarodni standard opredeljuje metodo za določanje ε-kaprolaktama in ω-lavrolaktama v poliamidih s plinsko kromatografijo. Primerna je zlasti za določanje ε-kaprolaktama v poliamidu 6 in ω-lavrolaktama v poliamidu 12. Z upoštevanjem, da plinska kromatografija ponuja širok razpon mogočih pogojev, je določena metoda tista, ki je bila dokazano primerna v praksi.
Določeni sta dve različici osnovne metode:
⎯ Metoda A je ekstrakcijska metoda, pri kateri se izvleček po metanolnem vrenju vbrizga v plinski kromatograf.
⎯ Metoda B je metoda, pri kateri se uporablja topilo, raztopina pa se vbrizga v plinski kromatograf.
