摘要： A gas sensor and method for manufacturing a gas sensor is provided. In order to increase the selectivity and the sensitivity to a gas to be measured, a gas-sensitive gallium oxide layer of a gas sensor is coated with a filter layer that comprises silicon dioxide. In an alternative embodiment, the gallium oxide layer can be coated with a gas-sensitive metal oxide layer made of titanium oxide, aluminum vanadate, tungsten oxide or tantalum oxide.

摘要： A method and apparatus for detecting methane in a gas mixture that may contain commonly used solvents including alcohols and acetones is provided which measures a change in electrical resistivity, electrical conductivity or relative permeability caused by the presence of methane gas at a chemically active sensing structure. The apparatus includes two spaced-apart electrodes that are covered with a thin methane-sensitive semi-conductive metal oxide layer. The gas to be tested is heated to a temperature exceeding 740.degree. C. before it contacts the metal oxide layer. Alcohols, acetones and other solvents are oxidized to electrical carbon dioxide and water before they reach the metal oxide layer so that only the less reactive and reducing gas methane reaches the metal oxide layer where it is reduced and increases the conductivity of the metal oxide layer as measured between the two spaced-apart electrodes with an appropriate electrical meter instrument.
