  • Patent number: 11977007
    Abstract: Siloxane compounds are removed from the atmospheres by silica supporting an organic sulfonic acid compound. The silica with the organic sulfonic acid compound has a specific surface area down to 500 m2/g and up to 750 m2/g and a pore volume down to 0.8 m3/g and up to 1.2 m3/g, both measured by nitrogen gas adsorption method and has a pore diameter down to 4 nm and up to 8 nm, at the peak of differential pore volume measured by nitrogen gas adsorption method. The durability of gas sensing element against siloxanes is improved.

  • Publication number: 20210164929
    Abstract: A gas detection unit is accommodated within a housing of a gas sensor and the outside atmosphere of the housing is introduced through the filter to the gas detection unit. The filter comprises an organic polymer gas-permeable filter removing siloxanes and an inorganic filter removing alcohols and passing gases to be detected.
