ABSTRACT:
A gas chromatograph has a sample vaporization chamber connected to a column for vaporizing a liquid sample injected therein and introducing this vaporized liquid sample with a carrier gas into the column. There is also a flow rate control device for controlling the flow rate of the carrier gas either as it is being supplied into the vaporization chamber or as it is being discharged from the vaporization chamber through a discharge route other than the column for keeping the gas pressure approximately constant inside the vaporization chamber. A leakage detector detects a leakage of gas from the vaporization chamber on the basis of either a target value set for the flow rate control device or a monitored value of the flow rate. A warning device outputs a warning when a gas leakage is detected by the leakage detecting device.
