摘要
论述了一种新的测定粗苯馏程的方法 ,用注射器直接进样 ,用保留时间定性 ,用面积归一化法乘以经验系数定量。与传统的蒸馏方法相比 ,分析时间由 1～ 2 h缩短到 1 5～ 2 0 min,具有进样量少、操作简便。
An improved gas chromatographic method for determining the crude benzene was described.The sample of crude benzene was gotten by injector and was detected by retention time, and its concentration was determined by area method multiplying an experienced coefficient.Compared with the traditional distilling method, analytical time is decreased from 1～2 h to 15～20 min. The virtue of this method was fewer sample ,convenient operation and more accurate results.
