PURPOSE:To detect combustible gaseous components with high accuracy without using gaseous hydrogen by constituting at least the measuring gas side of electrodes to which a carrier gas is supplied of molybdenum disilicide or other non-catalytic materials. CONSTITUTION:A specified amt. of air or gaseous oxygen is mixed with the gaseous components which are to be measured and are eluted from a sepn. column provided with electrodes on both sides of a solid electrolyte sensor and is transported with the carrier gas to one side of the electrodes. A reference gas is introduced to the other electrode side. The components to be measured are detected by detecting the difference in electromotive force generated between the electrodes. At least the measuring gas side of the electrodes to which the carrier gas is supplied is constituted of the molybdenum disilicide or other non-catalytic materials. The combustible gaseous components are detected with high accuracy in such a manner without using the gaseous hydrogen. |
