A gas chromatograph which had a copper oxide oxidation tube heated to 600°C between a column and a thermal conductivity detector was examined for the analysis of a gas mixture involving hydrogen with helium carrier.<BR>Each of the column effluent was thus oxidized to water or carbon dioxide, and then detected by the conductivity detector.<BR>Calibration lines with good linearity covering wide range of concentration were obtained for hydrogen, carbon monoxide, methane and carbon dioxide, and 10ppm of hydrogen was detected on 1m<I>l</I> of sample volume. Adsorption loss of gases on the oxidizing agent and peak distortion were not observed.
