Abstract: A gas chromatograph main body (2) comprising an upper surface on which a plurality of injection ports are provided, an injector (4A) arranged on the gas chromatograph main body (2), for corresponding to an injection port (10-1 to 10-4) optionally selected from a plurality of the injection ports (10-1 to 10-4), and being configured to inject a sample through the corresponding injection port (10-1 to 10-4), and a sampler (6) for supplying a vial containing liquid to the injector (4A). The sampler (6) is arranged at a position determined according to a position of the injector (4A) on the gas chromatograph main body (2) so as to have a specific positional relationship with the injector (4A). The sampler is engaged with the gas chromatograph main body (2) or the injector (4A).

Abstract: A gas chromatograph includes first and second sample vaporization units, first and second separation columns, first and second carrier gas suppliers, a column oven that contains the first and second separation columns and has a first heater, first and second detectors, a first auxiliary gas supplier that supplies an auxiliary gas to the first separation column and a controller that executes control by increasing a supply pressure of an auxiliary gas applied by the first auxiliary gas supplier to a pressure higher than a pressure during an analysis of a sample and lowering a supply pressure of a carrier gas applied by the first carrier gas supplier to a pressure lower than a pressure during the analysis of the sample such that the supply pressure of the auxiliary gas is higher than the supply pressure of the carrier gas, and sets a first maintenance switch mode in which the first sample vaporization unit is maintainable.

Abstract: A controller includes a temperature prediction unit. The temperature prediction unit predicts, on the assumption that a refrigerant is fed from a refrigerant feeder, an internal temperature of a column oven based on time interval information and decrement information in a memory. Thus, the temperature prediction unit can accurately predict the internal temperature of the column oven when the refrigerant is fed from the refrigerant feeder. If the refrigerant is fed from the refrigerant feeder when the predicted internal temperature of the column oven is suitable for the analysis operation, the internal temperature of the column oven can be brought closer to an appropriate temperature. As a result, the internal temperature of the column oven can be controlled with precision.

Abstract: A gas chromatograph includes a sample introduction portion and a heater block. A contact portion is fit into a first recess of a main body of the sample introduction portion. The heater block is fixed to and positioned with respect to the main body of the sample introduction portion by directly coming into contact with the contact portion provided on the main body of the sample introduction portion. For this reason, the heater block may be surely positioned with respect to the sample introduction portion. In addition, the heater block may be positioned without providing a member such that heat from the heater block is transferred to the outside and lost, and thus the sample introduction portion may be efficiently heated.

Abstract: A storage stores information of a peak start point, a peak end point, a peak top, and a boundary point and a boundary line between consecutive peaks of a chromatogram, as peak information. The selection processing unit selects the peak information or any peak included in the chromatogram based on the location of a touch gesture to the chromatogram displayed on a display monitor. This configuration contributes to preventing information different from information intended by an operator from being accidentally recognized when the operator makes a touch gesture to a touchscreen display monitor displaying the chromatogram. A correct input signal corresponding to the touch gesture on the touchscreen can thus be transmitted.
