Method for analyzing gas and device for analyzing gas

A device for analyzing a gas, comprising:

• a plurality of adsorbents respectively having compositions that are different from each other;
• a plurality of housing parts individually storing the plurality of adsorbents, respectively;
• a gas inlet for introducing a sample gas to be analyzed to each of the plurality of housing parts;
• a plurality of gas-guiding passages that are connected between the gas inlet and the plurality of housing parts and guide the sample gas;
• a detector that detects the sample gas desorbed from each of the plurality of adsorbents;
• a plurality of desorbed-gas passages connecting the plurality of housing parts to the detector, the plurality of housing parts being disposed between the plurality of gas-guiding passages and the plurality of desorbed-gas passages;
• and
• an identifier that acquires a detection signal from the detector and specifies a component contained in the sample gas.
