PURPOSE:To simultaneously and rapidly analyze multiple components only by immersing a probe in molten steel, by providing a gas introducing port and a gas exhaust port to the upper end part of the probe and positioning the leading end of the feed-in passage connected to said introducing port under the liquid level of collected molten steel while connecting a gas measuring apparatus to said exhaust port. CONSTITUTION:A gas introducing port 5 and a gas exhaust port 6 are provided to the upper end part of a probe and a gas feed-in passage 7 for introducing oxygen gas into collected molten steel C is formed from the introducing port and arranged so that the leading end is positioned at least under the interface of collected molten steel C. A gas measuring apparatus for measuring the gas generated from collected molten steel C is connected to the gas exhaust port 6. Thus constituted probe is inserted in molten steel A to feed oxygen gas in the molten steel C flowed in the probe and oxygen is reacted with C, S, N and H in the molten C to take out the formed gas which is, in turn, fed in the gas measuring apparatus. By this method, multiple components can be analyzed rapidly and simultaneously only by immersing the above mentioned probe in molten steel A.
