1. A gas chromatograph comprising:
a sample gas generator configured to generate a sample gas from an injected sample;
a separation column connected such that the sample gas generated in the sample gas generator is introduced thereinto and configured to separate components of the introduced sample gas;
a gas supply source configured to supply a carrier gas to the sample gas generator to carry the sample gas from the sample gas generator to the separation column when the components of the sample gas are analyzed;
a controller configured or programmed to acquire an in-analysis usage amount of the carrier gas based on an analysis time for analyzing the components of the sample gas, and a flow rate of the carrier gas supplied from the gas supply source to the sample gas generator; and
a display configured to display the in-analysis usage amount acquired by the controller.
