。[Scope of Claim for Utility Model Registration] A high-boiling point component detection stream leading to a high-boiling point component detector downstream of a carrier gas flow path formed by connecting a carrier gas supply section, a sample introduction section, and a column for separating high-boiling point components in this order. The low-boiling point component detection flow path is branched from the branch part of the high-boiling point component detection flow path to the high-boiling point component detector via the low-boiling point component separation column and the low-boiling point component detector. Between the branch part of the low boiling point component detection channel and the low boiling point component separation column, a gas introduction pipe capable of increasing the pressure in these detection channels by introducing gas is provided, and
Each of these gas introduction pipes is provided with an on-off valve, and when one of these on-off valves is opened and the other is closed, a pressure equivalent to the gas pressure of the carrier gas flow path at the branch part is applied from the gas introduction pipe to the branch part. A gas chromatograph equipped with a pressure adjustment section that can apply pressure to the air.
