ISO 24538:2008规定了测定氯乙烯均聚物和共聚物树脂中残留氯乙烯单体的方法。
该方法基于静态顶空气相色谱技术(即在恒温下分析气相与固相的平衡),适用于所有类型的均聚物和共聚物树脂。直接在粉末状树脂上进行。
ISO 24538:2008 specifies a method for the determination of residual vinyl chloride monomer in homopolymer and copolymer resins of vinyl chloride.
The method is based on a static headspace gas-chromatographic technique (i.e. the analysis of the vapour phase in equilibrium with the solid phase at constant temperature) and is suitable for all kinds of homopolymer and copolymer resin. It is done directly on the resin in powder form.
