中文名称：制革工业用化学品 某些双酚总含量的测定

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

本文件规定了皮革鞣制工业用化学品中下列双酚的总含量（溶剂可提取物）的测定方法:—？双酚A；—？双酚AF；—？双酚B；—？双酚F；—？双酚S。该方法需要使用液相色谱(LC)与单四极杆质谱仪(MS)、三重四极杆质谱仪(MS/MS)、紫外(UV)检测器、二极管阵列检测器(DAD)或荧光检测器(FLD)来鉴定和定量双酚。笔记？1？该方法也可用于其他双酚，如果它们被实验室验证。笔记？2？FLD检测不到双酚S。

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.
