  • Publication number: 20230258615
    Abstract: A column 2 is provided in a gas capturing unit 20 for capturing sample gas. A gas supply unit 1 supplies carrier gas for sending sample gas into the column 2. A gas separation mechanism 100 guides carrier gas in the column 2 to the outside of the column 2 by setting the lead-out path 5 to negative pressure with respect to the inside of the column 2. A heating unit 23 heats the column 2 to desorb sample gas captured by the gas capturing unit 20. Sample gas desorbed from the gas capturing unit 20 is introduced into a cell 31. A light source unit 32 irradiates sample gas in the cell 31 with light. An analysis unit 3 analyzes sample gas based on an intensity change of light emitted by the light source unit 32.
