Determination of Benzene and toluene in Finished Motor and Aviation Gasoline with the Agilent 6820 GC System using ASTM Method D3606

Abstract: The Agilent 6820 gas chromatographic (GC) system configured with flame ionization detector and 6-port valve is used to analyze benzene and toluene in motor and aviation gasoline. In this method, the methyl silicone packed column OV-101 and a TCEP [1,2,3-tris(2-cyanoethoxy) propane) are used as precolumn and analytic column respectively. The concentration of each component is calculated by reference to the internal standard (methyl ethyl ketone). Agilent Cerity NDS software is used for 6820 GC control and data analysis. This application demonstrates that calibration and precision meet or exceed the ASTM D3606 specifications.
