(Main)Chemicals for the leather tanning industry - Determination of the total content of certain bisphenols (ISO 21135:2024)
Chemicals for the leather tanning industry - Determination of the total content of certain bisphenols (ISO 21135:2024)
This document specifies a method for determining the total content (solvent extractable) of the following bisphenols in chemicals for the leather tanning industry:
— bisphenol A;
— bisphenol AF;
— bisphenol B;
— bisphenol F;
— bisphenol S.
This method requires the use of liquid chromatography (LC) with either a single quadrupole mass spectrometer (MS), a triple quadrupole mass spectrometer (MS/MS), an ultraviolet (UV) detector, a diode array detector (DAD) or a fluorescence detector (FLD) to identify and quantify the bisphenols.
NOTE 1 This method can also be used for other bisphenols if they are validated by the laboratory.
NOTE 2 Bisphenol S cannot be detected with FLD.
Chemikalien für die Gerbereiindustrie - Bestimmung des Gesamtgehalts von einzelnen Bisphenolen (ISO 21135:2024)
Dieses Dokument legt ein Verfahren zur Bestimmung des Gesamtgehalts (lösemittelextrahierbar) der folgenden Bisphenole in Chemikalien fest, die in der Gerbereiindustrie verwendet werden:
Bisphenol A;
Bisphenol AF;
Bisphenol B;
Bisphenol F;
Bisphenol S.
Dieses Verfahren erfordert den Einsatz von Flüssigchromatographie (LC) entweder mit einem Single-Quadrupol-Massenspektrometer (MS), einem Triple-Quadrupol-Massenspektrometer (MS/MS), einem Ultraviolett (UV)-Detektor, einem Diodenarray-Detektor (DAD) oder einem Fluoreszenz-Detektor (FLD) zur Identifizierung und Quantifizierung der Bisphenole.
ANMERKUNG 1 Dieses Verfahren kann auch für andere Bisphenole verwendet werden, wenn sie vom Labor validiert wurden.
ANMERKUNG 2 Bisphenol S kann nicht mit FLD nachgewiesen werden.
Produits chimiques pour l’industrie du tannage du cuir - Détermination de la teneur totale en certains bisphénols (ISO 21135:2024)
Le présent document spécifie une méthode de détermination de la teneur totale (extractible par solvant) des bisphénols suivants dans les produits chimiques utilisés par l’industrie du tannage du cuir:
— le bisphénol A;
— le bisphénol AF;
— le bisphénol B;
— le bisphénol F;
— le bisphénol S.
Cette méthode nécessite de recourir à la chromatographie en phase liquide (CL), couplée soit à un spectromètre de masse à simple quadripôle (MS), soit à un spectromètre de masse à triple quadripôle (MS/MS), soit à un détecteur ultraviolet (UV), soit à un détecteur à barrettes de diodes (DAD) ou un détecteur de fluorescence (FLD), afin d’identifier et de quantifier les bisphénols.
NOTE 1 Sous réserve de validation par le laboratoire, cette méthode peut également être utilisée pour d’autres bisphénols.
NOTE 2 Le bisphénol S ne peut pas être détecté au moyen d’un FLD.
