Abstract
A gas measuring device includes: a gas rectification unit configured to rectify gas to control traveling directions and traveling speeds of gas molecules based on molecular weights of the gas molecules; and a gas sensor configured to absorb the gas molecules of the gas rectified by the gas rectification unit, and to detect absorption positions and absorption amounts.
Claims8
A gas measuring device comprising:
- a plate-like filter including a principal surface on which a plurality of slits parallel to one another are formed, the principal surface being parallel to a flow direction of gas, and an extending direction of each of the plurality of slits being orthogonal to the flow direction of the gas, and configured to control traveling directions and traveling speeds of gas molecules based on molecular weights of the gas molecules by causing the gas molecules to pass, based on gravity, through slits corresponding to their respective molecular weights;
- and
- a gas sensor configured to absorb the gas molecules of the gas, which have been rectified by the filter so that the gas molecules have reached different positions based on the molecular weights of the gas molecules, and to detect absorption positions and absorption amounts of the gas molecules,
- wherein components of the gas are specified based on the absorption positions and the absorption amounts of the gas molecules.
