SEMICONDUCTING OXIDE GAS SENSORS AND MATERIALS THEREFOR.

摘要

The selectivity of response of resistive gas sensors to specific gases or vapours is improved by the selection of specified gas-sensitive materials which are not previously known for the applications described, which include detection of hydrocarbons in the presence of CO, H2S, SO2, chlorine, NO2, CO2 (especially in low concentrations), CFC's ammonia, free oxygen by determination of partial pressure and numerous organic gases and vapours.
