BS ISO 19619:2018规定了测定由环氧丙烷共聚物合成的表面活性剂中游离环氧丙烷的分析程序。该方法适用于通过顶空气相色谱（HS-GC）和基于外部程序的火焰离子化检测器（FID）定性和定量测定环氧丙烷加合物、聚醚和聚乙二醇酯中的环氧丙烷基团。气相色谱-质谱（GC-MS）用于确认目的。交叉引用:ISO 3696ISO 607ISO 5725-2购买本文件时提供的所有现行修订版均包含在购买本文件中。

BS ISO 19619:2018 specifies an analytical procedure for the determination of free propylene oxide in surfactants which are synthesized from propylene oxide copolymers.The method is appropriate for the qualitative and quantitative determination of propylene oxide groups in propylene oxide adducts, polyethers and polyglycol esters by headspace gas chromatography (HS-GC) with a flame ionization detector (FID) based on external procedure. Gas chromatography-mass spectrometry (GC-MS) is used for the confirmatory purposes.Cross References:ISO 3696ISO 607ISO 5725-2All current amendments available at time of purchase are included with the purchase of this document.
