摘要
利用气相色谱中加载的SCD(硫化学发光)检测器考察了分流比、柱流速等因素对硫含量的影响,建立了轻质油品中痕量硫的分析方法,方法测定下限达到0.05mg/L,相对标准偏差小于3%,加标回收率在100%~105%。
In this paper,a gas chromatographic method for the determination of trace sulfur in light oil was established.The influence of shunt ratio,column velocity and other factors on sulfur content was investigated by using SCD(vulcanization luminescence)detector loaded in gas chromatography.The lower limit of the method is 0.05 mg/L,the relative standard deviation is less than 3%,and the recovery rate of standard addition is 100%~105%.
