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
