Gas measurement components and gas measurement methods

Abstract

This invention discloses a gas measurement component and a gas measurement method, relating to the field of gas detection technology. The gas measurement component includes: a first sampling device, a second sampling device, a driving device, and a detection device. The first sampling device includes a first enrichment cavity through which a paper tape passes and a first gas channel through which gas flows in a direction perpendicular to the paper tape. The second sampling device includes a second enrichment cavity through which a paper tape passes and a second gas channel through which gas flows in a direction perpendicular to the paper tape. The driving device is configured to drive the paper tape to move along a travel trajectory and to drive the paper tape located in the first sampling device and the paper tape located in the second sampling device to move independently of each other. The detection device is movable between a first position opposite to the first sampling device and a second position opposite to the second sampling device. According to embodiments of the gas measurement component of this invention, the measurement component can improve sampling efficiency and is economical and practical.
