GC-FPD测定粗苯中二硫化碳及噻吩含量

Determination of Carbon disulfide and Thiophene Content in Crude benzene by GC-FPD Gas Chromatography

建立了气相色谱法测定粗苯中二硫化碳及噻吩含量的分析方法。将粗苯以甲醇为溶剂稀释,采用GC-9A岛津气相色谱分离,FPD检测器检测,指数法分别对粗苯中的二硫化碳、噻吩进行定性定量分析。该方法分离效果好,测定的结果具有良好的准确度和精密度,整个试样分析时间不超过6 min。

A chromatography method for determination of carbon disulfide and thiofuran content in the crude benzene was established. The method used methanol as the solvent, and crude benzene was separated by GC-9A gas chromatography, and was determined by FPD detector and qualitative and quantitative analysis of the carbon disulfide and thiofuran was carried out by the index method. The results show that, the method has good separating effect, accuracy and precision, the whole analysis process only needs less than 6 min.
