Title: GAS ANALYZING DEVICE AND GAS ANALYZING METHOD
Abstract:
In order to ensure a separation ability required of an oxidation catalyst such as a non-methane cutter, and to enable a sample gas to be measured accurately, this gas analyzing device is provided with: a sample gas line L1 through which a sample gas flows; an analyzer 10 which is provided in the sample gas line L1 and which detects the concentration of a specific component contained in the sample gas; a catalyst 20 which is provided upstream of the analyzer 10 in the sample gas line L1 and which reacts with the sample gas; and a moisture concentration adjusting unit 30 which is provided upstream of the catalyst 20 in the sample gas line L1 to adjust the moisture concentration of the sample gas.
