摘　　要：建立了一种分析炼厂液化石油气烃类组成的气相色谱分析方法,采用FID检测器、Al2O3毛细管色谱柱,自动液体四通阀进样,校正面积归一化法定量计算分析结果,解决了行业中用填充柱、TCD检测器分析时灵敏度低,分离效果不好,不能检测出双烯烃的问题。该方法灵敏度高、分析速度快、准确度高、重复性好。A method of gas chromatography was established to determine hydrocarbon composition in liquefied petroleum gases of refinery, using FID detector, Al2 O3 capillary column, automatic liquid four-way valve sampling. And quantitative calibration area normalization method was used to calculate the analyzed results, which solved the problem of low sensibility and bad isolation effect of packed column and TCD detector in industry. The method has high sensibility, quick analysis speed, high accuracy and better repeatability.
