Title:
ガス検出装置及びガス検出方法
Document Type and Number:
Japanese Patent JP7114161
Kind Code:
B2
Abstract:
Provided are a gas detection device and gas detection method that make it possible to detect a trace amount of gas. A gas detection device (10) comprises a gas sensor (1) for detecting a gas to be detected and a sealed space formation part (20) that accommodates the gas sensor (1) and the gas to be detected in the same space. This gas detection method comprises a step for keeping the gas sensor (1) at a constant temperature, a heating step for putting a porous gas molecule adsorption material (3) into a heated state, and a detection step for detecting a specific gas according to the variation in the output of a thermosensitive resistance element (2) resulting from the heating.
