摘要
使用气相色谱法,硫化学发光检测器(SCD)及外标法定量,对石油苯中痕量噻吩进行测定。确定了燃烧器操作温度、气体流速等检测器条件,对干扰找到了解决的办法。与其他检测方法相比较,具有操作简单,检测快速,灵敏度高,检测限低,干扰少,测定结果重复性好等优点,分析结果更加准确可靠。
Trace thiophene in petroleum benzene was determined using sulfur chemiluminescence detector（SCD） and gas chromatography and external standard method.The detection conditions burner temperature and gas flow rate were determined,and a solution to the inference was found out.Compared with other detection methods,this method had the advantages of simple operation,rapid detection,high sensitivity,low detection limit,less interference,and measurement result with good repeatability,and the analysis results were more accurate and reliable.
