CERAMIC H2S SENSOR

摘要

A sensor capable of monitoring hydrogen sulfide in a hydrogen-containing background. The sensor comprises novel sulfur sensitive materials that may be deposited as a thin film or thick film in a chemi-resistor format. The novel sulfur sensitive materials may comprise a single component oxide material or a composite of two or more oxide materials. The sensors respond reversibly to H₂S in a reducing gas environment, with a corresponding change in their electrical resistance that can be used to quantify the amount of H₂S present in the reducing gas.
