Chemicals for the leather tanning industry - Determination of the total content of certain bisphenols (ISO 21135:2024)

This document specifies a method for the determination of the total content of certain bisphenols in chemicals used in the tanning
industry

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.
