标准范围

本文件规定了一种通过溶剂萃取和气相色谱负离子化学电离质谱(GC-NCI-MS)测定纺织品中,特别是涂层织物的聚合物、由聚合物制成的印刷品和由聚合物(例如聚氯乙烯)制成的纽扣中的短链氯化石蜡(SCCP:C10-C13)和中链氯化石蜡(MCCP:C14-C17)的量的色谱方法。

This document specifies a chromatographic method to determine the amount of short-chain chlorinated paraffins (SCCPs: C10-C13) and middle-chain chlorinated paraffins (MCCPs: C14-C17) in textile articles, especially in polymer of the coated fabrics, prints made of polymer and buttons made of polymer (e.g. polyvinylchloride) by means of solvent extraction and gas chromatography negative ion chemical ionization mass spectrometry (GC-NCI-MS).
