Special gas chromatograph for analyzing the content of benzene and toluene in gasoline- Shanghai Sci Tech Innovation Chromatography (under the same parent company)
Instrument Features
Benzene and toluene are toxic and harmful substances that can cause a decrease in white blood cells and a decline in immune function when inhaled by the human body. Benzene, toluene and other benzene derivatives are also carcinogenic substancesAfter phasing out leaded gasoline, a large amount of aromatic compounds were added to gasoline to maintain its octane rating(30%~50%After the combustion of gasoline, a large amount of benzene and toluene, among other benzene derivatives, are emitted into the ambient air from the exhaust of automobiles.
this company The dedicated gas chromatography method for determining the content of benzene and toluene in gasoline ensures the stability of the instrument by preventing sample components from remaining in the instrument during the measurement process. Due to the adoption ofFIDDetector, analysis sensitivity, detection limit for benzene and toluene content can reach10-6Level. Precision analysisRSD<5.0%. The analysis method is simple and easy to operate, and the analysis time for each sample is about10About minutes. This method can meet the needs of determining the content of benzene and toluene in gasoline in various situations.
