皮革鞣制工业用化学品 环硅氧烷的测定

[中文适用范围]： 本文件规定了在皮革鞣制工业用化工产品中测定下列环硅氧烷总量的方法：八甲基环四硅氧烷（D4）；十甲基环五硅氧烷（D5）；十二甲基环六硅氧烷（D6）。此方法要求使用配备单四极杆质谱仪的气相色谱仪（GC-MS）来鉴定和定量这些环硅氧烷。 [外文原描述]： This document specifies a method for determining the total content of the following cyclosiloxanes in chemicals for the leather tanning industry: — octamethylcyclotetrasiloxane (D4); — decamethylcyclopentasiloxane (D5); — dodecamethylcyclohexasiloxane (D6); This method requires the use of gas chromatography (GC) equipped with a single quadrupole mass spectrometer (MS) to identify and quantify the cyclosiloxanes.
