Abstract
<PICT:0721077/III/1> Combustible constituents of a gas are determined by passing the gas mixed with air successively through two chambers 15, 16 preferably set in a solid block 1, the chambers being preheated by coils (not shown) to the same temperature which is higher than the ignition temperature of the constituent to be determined and may be below the ignition temperature of another constituent not to be determined. Combustion occurring in the first chamber 15 causes a rise in temperature which is determined e.g. by a multiple thermo-couple, the junctions 12 of which are in thermal contact with the walls of the two chambers, or by resistance thermometers inside or outside the chambers.
