毛细管气相色谱法测定2^#混合苯中C6—C10苯系芳烃

Determination of Benzene and C_7-C_(10) Alkyl Substitute Benzenes in No. 2 Mixed Benzene by Capillary Gas Chromatography

介绍一种毛细管气相色谱测定２００℃以前加氢汽油馏分２￣＃混合苯中Ｃ＿６－Ｃ＿（１０）苯系芳烃的新方法。该法以氮气为载气，样品经交联甲基硅橡胶特效熔硅毛细柱分离，采用内标法定量，简便、快速、准确，适于２￣＃混合苯出口质量控制分析。

A new method for the determination of benzene and C_7-C_(10) alkyl substituted benzenein No. 2 mixed benzene by capillary gas chromatography(CGC) is presented. This method isbased On nitrogen as carrier, the sample is determined by internal standard method afterseparation with cross-linked methyl silicone special performance fused silica capillary colum.It is simple and easy to operate and is rapid and accurate for obtaining satisfactory results. This method is applicable for quality control.
