Gas chromatography for analyzing the content of benzene and toluene in gasoline

Description：

Benzene and toluene are toxic and harmful substances. Inhalation by the human body will reduce the number of white blood cells in the blood and reduce the immune function. Benzene, toluene and other benzene series are carcinogens. The World Health Organization and the US EPA believe that when people are exposed to 1ug/m3 of benzene, 4 to 8 people per million people are at risk of leukemia. After the elimination of leaded gasoline, in order to maintain the octane number of gasoline, a large amount of aromatic hydrocarbon compounds (30% to 50% volume ratio) were added to the gasoline. After the gasoline is burned, there will be a large amount of benzene and Toluene and other benzene series compounds are emitted into the ambient air.

A special gas chromatography method for measuring the content of benzene and toluene in gasoline. During the measurement process, the sample components will not remain in the instrument, thus ensuring the stability of the instrument. Due to the use of FID detector, the analysis sensitivity is extremely high, and the detection limit of benzene and toluene content can reach 10-6 level. Analytical precision RSD <5.0%. The analysis method is simple and easy to operate, and the analysis time for each sample is about 10 minutes. This method can meet the needs of determination of benzene and toluene content in gasoline under different occasions.
