| Resumen: | 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. NOTE 1 This method can also be used
for other bisphenols if they are validated by the laboratory.
NOTE 2 Bisphenol S cannot be detected with FLD.
