英文名称：Chemicals for the leather tanning industry — Determination of the total content of certain bisphenols
发布日期：2024-05
标准范围
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.
