Leather — Determination of total content of certain bisphenols
Edition 1
2023-07
2023-07
Abstract
This document specifies a method for determining the total content (solvent extractible) of the following bisphenols in leather:
— bisphenol A;
— 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 This method can also be used for other bisphenols if they are validated by the laboratory.
