PROBLEM TO BE SOLVED: To obtain a highly accurate analysis result even if the atmospheric pressure is changed, in a gas chromatographic device. SOLUTION: This gas chromatographic device is equipped with a sampling gas supply part 10 for supplying sampling gas, a gas sampling part 11 for collecting a fixed quantity of the sampling gas, a gas component separation part 12 for separating the collected sample gas into each gas component, a gas component quantity detection part 13 for detecting component quantities of each separated gas component, and outputting peak waveforms corresponding to the component quantities, and a data processing part 14 for comparing an area of the peak waveform with a reference area of the peak waveform set beforehand at the adjusting time of a device body, and calculating each gas component concentration in the sample gas. In the gas chromatographic device, a pressure detector 16 for detecting the pressure of the sample gas when collecting the sample gas, and a correction operation part 15 for comparing a detected pressure by the pressure detector 16 with a reference pressure set beforehand at the adjusting time of the device body, and correcting each gas component concentration in the sample gas, are provided.
