Research on the Determination of Benzene Content in Gasoline Based on Gas Chromatography
After reducing the benzene content in gasoline according to the National Ⅵ Quality Standard and adjusting the benzene volume fraction from≤1%to≤0.8%,it is necessary to determine the benzene content in gasoline to ensure the quality of the oil product.Based on the differences in various measurement methods,this article will apply gas chromatography(dual column series-blowback system)to analyze the content of benzene in gasoline.To this end,an overview of experimental instruments,reagents,and chromatographic conditions is provided.Based on experimental principles,analyze the experimental processes of standard curve determination,detection limit determination,accuracy determination,precision determination,etc.Finally,the experimental results were discussed,and the Determination of Benzene and Toluene Content in Automotive Gasoline and Aviation Gasoline-Gas Chromatography Method(SH/T 0713-2002)can be used to determine the benzene content in gasoline.
