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.

Abstract: A gas measurement apparatus includes an optical resonator that resonates light, a light source that generates light for irradiation of the optical resonator, and a photodetector that detects light taken out of the optical resonator. The optical resonator includes a plurality of mirrors, a holding member, a hollow tubular member, a hollow tubular member, and a temperature adjustment instrument. The holding member is lower in thermal expansion coefficient than the hollow tubular member. The hollow tubular member includes a portion higher in thermal conductivity than the holding member and a bellows higher in elasticity than a first portion. The hollow tubular member is equal to or higher than the hollow tubular member in thermal conductivity, and is provided as far as positions of the plurality of mirrors on an inner side of the bellows.
