Abstract
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.
