标准范围

本文件规定了氯乙烯均聚物和共聚物树脂及配混材料中氯乙烯单体的测定方法。该方法基于样品溶解和顶空气相色谱法。氯乙烯浓度在0.1？mg/kg至3.0？可以确定mg/kg。

This document specifies a method for the determination of vinyl chloride monomer in homopolymer and copolymer resins of vinyl chloride and compounded materials. The method is based on sample dissolution and headspace gas chromatography. Concentrations of vinyl chloride in the range 0,1 mg/kg to 3,0 mg/kg can be determined.
