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 m/g and up to 750 m/g and a pore volume down to 0.8 m/g and up to 1.2 m/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.

Gas detection device and gas detection method

A gas detector comprises a gas detection unit and a filter introducing surrounding atmosphere to the gas detection unit. The filter comprises a gas-permeable organic polymer membrane having an acidic group or a basic group.
