• The authors applied gas chromatography to the determination of oxygen in iron and steels by composing a special equipment for it. The sample was fused with graphite crucible under atmosphere of helium gas in a high frequency combustion furnace of 2 kW and 450 kilocycles. Carbon monoxide and others gases extracted from the molten metal were swept with helium and were separated mutually by gas chromatography. The amount of oxygen was obtained from the amount of carbon monoxide. When 1 g of a metal specimen was supplied for analysis, the detection limit of oxygen gas was about 10 ppm. Standard deviation of the result was about 6%.<BR>The method and the apparatus were effectively applied for the determination of oxygen in iron and steels.
