PROBLEM TO BE SOLVED: To provide a gas chromatography device capable of measuring accurate concentration, at all times, even regarding a component that varies in peak area due to adsorption, without accompaniment of a change in the carrier gas. SOLUTION: The gas chromatography device is constituted so as to analyze a sample gas Gs, by using the carrier gas Gc, has a region (column C1), having adsorbability with respect to a specific component in the sample gas Gs, and is equipped with auxiliary gas Go containing the specific component and the flow-channel change-over means V2, provided to the front stage of the region (column C1) and allowing the auxiliary gas Go to selectively flow to the region (column C1), prior to having the sample gas Gs flow to the region (column C1).
