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.

Abstract: An information processing apparatus capable of communicating with a plurality of chromatograph apparatuses includes a display unit, a display processing unit, and an operation receiving unit.

Abstract: A gas chromatograph is provided with a communication unit, a setting processing unit, a first operation reception unit, and a maintenance processing unit. The communication unit communicates with an outside. The setting processing unit sets any one of the plurality of maintenance modes to a default maintenance mode in response to an input from the outside via the communication unit. The first operation reception unit is provided in the housing and is configured to accept a progress operation for progressing a maintenance sequence corresponding to the default maintenance mode. The maintenance processing unit progresses the maintenance sequence stepwise each time the progress operation is accepted by the first operation reception unit. The first operation reception unit is commonly used even in a case where any one of the plurality of maintenance modes is set to the default maintenance mode.

Abstract: In a gas chromatograph 1, a back-pressure calculation processor 242 calculates a back pressure for a first detector. The pressure calculation processor 243 calculates a pressure of a carrier gas in a branching part. The back-flow determination processor 244 compares the pressure of the carrier gas in the branching part calculated by the pressure calculation processor 243 with the back pressure of the first detector calculated by the back-pressure calculation processor 242, and if the pressure of the carrier gas in the branching part is smaller than the back pressure of the first detector, the back-flow determination processor 244 determines that the carrier gas will flow back. It is therefore possible to surely know that there is a possibility that a back-flow of the carrier gas will occur, by checking the determination result of the back-flow determination processor 244.
