Leather. Determination of total content of certain bisphenols. | Status: Current

1 Scope 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.
