A method for the quantitative analysis of the composition of a gas mixture is specifically suited for the analysis of the atmosphere of a containment in a nuclear installation. Even under difficult conditions, this method enables the simple, reliable and as direct as possible determination of physical parameters, thereby permitting the characteristic definition of the ignition field and the combustion behavior of the gas mixture. A measuring device is provided with a thermal conductivity detector with a first measuring bridge, a thermal tonality detector with a second measuring bridge, and a common evaluation unit. With reference to bridge voltages present on the two measuring bridges, the hydrogen content and the oxygen content are simultaneously determined in the evaluation unit. |
