<p>A gas chromatograph of high reliability measurement in which the base line of the output of a sensor is stable and an expired air component analyzer. The gas chromatograph comprises a gas separation column incorporating a member for causing a flow delay depending on the gas component, an air pump for feeding air as a carrier gas into the gas separation column, a gas supply port provided in a gas passage extending between the air pump and the gas separation column and adapted to feed a gas to be analyzed and containing a detection object gas component in the carrier gas flowing through the gas passage, a buffer tank provided upstream from the gas supply port, and sensing means for detecting a gas component of the gas supplied in the gas separation column.</p> |
