By means of gas sampling and gas chromatography, the process of mixture formation was observed in case that a volatile fuel was injected into the preheated air in a constant volume combustor. For the estimation of the density of an unburned mixture, it is necessary to measure both quantities of fuel and air in the mixture. In the ordinary method for that purpose, some exclusive gas chromatographs are used for organic and inorganic gas analyses, so that the same sample should be put into respective chromatographs. In order to diminish the accompanying troublesome procedures, the piping of columns in a gas chromatograph is so devised as to analyze simultaneously both components. Once a sample gas is put into this gas analyzer, both organic and inorganic components can be detected at the same time.
