Leather - Determination of total content of certain bisphenols (ISO 11936:2023)

This document is a method for determining the total content (solvent extractible) of the following bisphenols:
—   Bisphenol A
—   Bisphenol B
—   Bisphenol F
—   Bisphenol S
This method requires the use of liquid chromatography (LC) with triple quadrupole mass spectrometer (MSMS) or with Diode Araay Detector (DAD) or FLD to identify and quantify the bisphenols.

Leder - Bestimmung des Gesamtgehalts von einzelnen Bisphenolen (ISO 11936:2023)

Dieses Dokument legt ein Verfahren zur Bestimmung des Gesamtgehalts (lösemittelextrahierbar) der folgenden Bisphenole in Leder fest:
   Bisphenol A;
   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   Dieses Verfahren kann auch für andere Bisphenole verwendet werden, wenn sie vom Labor validiert wurden.

Cuir - Détermination de la teneur totale en certains bisphénols (ISO 11936:2023)

Le présent document spécifie une méthode de détermination de la teneur totale (extractible par solvant) des bisphénols suivants dans le cuir :
—     le bisphénol A ;
—     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), à un spectromètre de masse à triple quadripôle (MS/MS), à un détecteur ultraviolet (UV), à un détecteur à barrettes de diodes (DAD) ou à un détecteur de fluorescence (FLD), afin d’identifier et de quantifier les bisphénols.
NOTE            Sous réserve de validation par le laboratoire, cette méthode peut également être utilisée pour d’autres bisphénols.

Usnje - Določevanje celotne vsebnosti nekaterih bisfenolov (ISO 11936:2023)

Ta dokument določa metodo za določanje skupne vsebnosti naslednjih bisfenolov (ki jih je mogoče izvleči s topili):
–   bisfenol A
–   bisfenol B
–   bisfenol F
–   bisfenol S
Ta metoda zahteva uporabo tekočinske kromatografije (LC) z masnim spektrometrom s trojnim kvadrupolom (MSMS) ali detektorjem z diodnim nizom (DAD) ali FLD za identifikacijo bisfenolov in ugotavljanje njihove količine.
