摘要
用530μm交联SE-54大口径石英毛细管柱及拟柱上(at-column)进样技术,完成高纯苯乙烯中微量杂质的快速分析,一次分析只需12min。各微量杂质分析结果的精密度及准确度都较好,二乙烯基苯的检出限达10ppm。
A styrene sample can be analyzed rapidly by wide bore (i. d. 530μm)fused silica capillary column within 12 minutes. The analysis time is about an hour faster than that of classical packed column. The stationary phase of the column is cross-linking SE-54. The precision and accuracy of data obtained by this method are same as that by classical packed column. The detection limit of divinylbenzene is 10ppm.
