| Zusammenfassung: | A catalytic combustion Wheatstone bridge type gas analyzer produces a mixture of gas and air by gaseous diffusion of the gas and air separately through porous walls into a reaction chamber to form the mixture, which contacts the catalytic element in the bridge circuit. The porosity of the walls is selected to permit gaseous diffusion transfer while preventing gaseous transfer into the reaction chamber by convection. The relative surface areas for diffusion of the gas sample and air are selected to provide a predetermined dilution ratio for the sample. |
