Adsorption apparatus and chemiluminescence type nitrogen oxide concentration meter

Abstract

An inner diameter of an opening of the flow path is larger than a particle diameter of an adsorbent. Therefore, in a state where the flow path 33 is disposed in the container 31, the adsorbent 40 enters the flow path 33 via the opening 33B of the flow path 33. That is, in the adsorption apparatus, the adsorbent is disposed in a region between a side surface portion of the container and the flow path and inside the flow path. Further, in the adsorption apparatus 3, the air flows the region between the container 31 and the flow path 33 and in the flow path 33. Therefore, when the air is flown into the adsorption apparatus 3, the air can be sufficiently brought into contact with the adsorbent 40, and moisture contained in the air can be sufficiently adsorbed.
