摘要
采用HP-INNOWAX大孔径毛细管色谱柱对丙烯腈单收液进行分离,经气相色谱-质谱联用分析,对24种组分进行定性。用氢火焰离子化检测器检测,采用内标法对样品中的杂质进行了定量分析。相对标准偏差和相对误差均小于10%。
The separation of acrylonitrile using single-pass recycle liquid was studied by using wide-holl chromatographic column( HP -innowax). The sample was analyzed by gas chromatography mass spectrometry( GC - MS). More than 24 components were identified. The sample was detected by flame ionization detector, and quantitated by internal standard method. The relative standard deviation and relative error were less than 10%.
