A columnis provided in a gas capturing unitfor capturing sample gas. A gas supply unitsupplies carrier gas for sending sample gas into the column. A gas separation mechanismguides carrier gas in the columnto the outside of the columnby setting the lead-out pathto negative pressure with respect to the inside of the column. A heating unitheats the columnto desorb sample gas captured by the gas capturing unit. Sample gas desorbed from the gas capturing unitis introduced into a cell. A light source unitirradiates sample gas in the cellwith light. An analysis unitanalyzes sample gas based on an intensity change of light emitted by the light source unit
