PROBLEM TO BE SOLVED: To reduce the wasteful consumption of a gas and to shorten the rising time of a gas chromatograph system at the start of analysis, in the gas chromatograph system. SOLUTION: The gas chromatograph system has an analyzing column; a carrier gas supply part for supplying a carrier gas to the analyzing column; a carrier gas flow rate regulating means for regulating the flow rate of the carrier gas, supplied to the analyzing column from the carrier gas supply part; a sample inlet section for introducing a sample into the carrier gas supplied to the analyzing column from the carrier gas flow rate regulating means; a detector for detecting the components of the sample separated according to each component by the carrier gas that flow out of the analyzing column; and a detector gas flow rate regulating means for regulating the flow rate of the detector gas supplied to the detector and is equipped with a detector gas flow passage on-off valve for opening and closing the detector gas flow passage that allows the detector gas flow rate regulating means to communicate with the detector.
