A gas chromatograph includes a sample gas generator, a separation column configured to separate components of an 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.

Gas chromatograph and carrier gas usage amount display method

A gas chromatograph comprises a sample gas generation unit, separation column, and detector. Multiple gas sources serve as carrier gases to transport sample gas to the separation column. A switching component connects the gas sources to the sample gas generation unit based on user-input information. This information is stored in a gas type memory, which aids a gas type identification component in determining the carrier gas type by monitoring the switching component's status and referring to the stored data.
