多维气相色谱法快速分析加氢汽油中苯乙烯含量

摘要

采用十通阀的反吹切换功能,将两根色谱柱和两个检测器连接起来,快速分析裂解加氢汽油中苯乙烯含量,采用外标法定量[1],该方法准确度和精密度均较高,分析快速简捷.%Two chromatographic columns and two detectors are connected by using the reverse blowing switching function of a 10-way valve.The external standard method is used for the quantitative analysis.The analytic result is accurate and precision.
