Surface active agents - Quantitative determination of free fatty acid in alkylamidopropylbetaines - Gas-chromatographic method

This European Standard specifies a procedure for the determination of the content of free fatty acid, FFA, in alkylamidopropylbetaines, which is defined as being the amount of fatty acid expressed in grams per 100 g of product.
This method has been validated for the determination of fatty acids from C6 to C20 in a total concentration range from 0,02  g to more than 3,0 g fatty acid per 100 g of product.

Grenzflächenaktive Stoffe - Quantitative Bestimmung freier Fettsäure in Alkylamidopropylbetainen - Gaschromatographisches Verfahren

Diese Europäische Norm legt ein Verfahren zur Bestimmung des Massenanteils an freier Fettsäure, FFA, in
Alkylamidopropylbetainen fest, der als Menge an Fettsäure in Gramm je 100 g des Produkts definiert ist.
Validiert wurde dieses Verfahren zur Bestimmung von C6- bis C20-Fettsäuren in einem Gesamtkonzentrationsbereich
der Fettsäure je 100 g des Produkts von 0,02 g/100 g bis größer 3,0 g/100 g.

Agents de surface - Dosage quantitatif des acides gras libres dans les alkylamidopropylbétaïnes - Méthode par chromatographie en phase gazeuse

La présente Norme européenne spécifie un mode opératoire de détermination de la teneur en acides gras libres des alkylamidopropylbétaïnes, définie comme étant la quantité d’acides gras exprimée en grammes pour 100 g de produit.
La présente méthode a été validée pour le dosage des acides gras de C6 à C20 dans une plage de concentration totale allant de 0,02 g à plus de 3,0 g d’acides gras pour 100 g de produit.
