A simple quantitative determination of ethanol in solution was attempted by gas chromatography using the head space technique.The apparatus was a gas chromatograph equipped with a thermal conductivity detector. The column packing was 5% PEG 20 M/Chamelite. The internal standard samples used were n-propanol and n-butanol. When a 1.0 volume % internal standard was added ti the alcoholic solution, the linear relation was estimated as 0.1 to 5.0 volume % ethanol between the concentration of ethanol and the peak area of ethanol vs. the peak area of the standard used.The marker method was also used to determine ethanol in sake, with about 16 volume % ethanol determined. These estimated values nearly equal those determined by the distillation method.
