Fast Analysis of Various Gas Components in Gasoline and Naphtha

A fast method for the analyses of gaseous hydrocarbon,CO 2 and H 2 S in gasoline and naphtha by gas chromatograph with multidimensional packed columns was developed.The gasoline sample was introduced directly and the calibration was normalized for quantitative analysis.The time for running a sample was about22min.The relative standard deviations of the retention times and the concentrations of the gas components in gasoline and naphtha samples were0.27%and4.5%,respectively.
