Analysis of Trace Benzene in Styrene by Capillary Flow Technique
Pages: 331-335
Year: Issue:  3
Journal: Petrochemical Technology

Abstract: 采用Agilent公司的微板流路控制技术中心切割装置,建立了一种简便测定苯乙烯中微量苯含量的二维气相色谱分析方法,并与ASTM D6229-06标准方法的阀切换技术进行了比较,两者定量分析结果具有较好的一致性.测定苯含量为0.21~82.20 mg/kg的苯乙烯试样时,微板流路控制系统和阀切换系统这两种方法的苯校正曲线相关系数r2分别为0.999 1,0.998 6,线性关系良好;标样回收率分别为...
