Abstract: A display area 60 of a display unit of a mass spectrometer shows a result of tuning. The display area 60 includes: a tuning-item displaying section 62 configured to display all tuning items and a result of whether each tuning item has been tuned; and an analyzable-condition displaying section 63 configured to display a condition under which an analysis is possible based on the result. The tuning items may be displayed respectively and individually. Alternatively, the tuning items may be displayed in a grouped manner with a plurality of tuning items in a group. Consequently, a user knows, at a glance, whether the tuning necessary for an analysis that the user intends to perform has been performed. If a necessary tuning item has not been tuned, the user immediately starts to tune (only) the tuning item. Further, a user immediately knows in a current state of tuning whether the analysis that the user intends to perform is possible. Therefore, when the analysis is possible, the user can start the analysis. When the analysis is impossible, the user can tune only the tuning item that has not been tuned and is displayed on the tuning-item displaying section 62.

Abstract: An extraction analysis device includes a placement table for placing a rack holding a plurality of extraction containers, and an analysis channel for analyzing a component extracted from a sample, and is configured to set the plurality of extraction containers held in the rack placed on the placement table as extraction targets in a preset order, to execute an extraction operation for extracting components from a sample to a mobile phase that is a supercritical fluid in the extraction container set as the extraction target, and to execute analysis of the components by introducing the components extracted by the extraction operation into the analysis channel. A rack replacement device is configured to execute replacement of the rack on the placement table by performing movement of the rack from the placement table of the extraction analysis device and placement of the rack on the placement table. The extraction analysis device is configured to bring the rack into a movable state in which the rack can be moved from the placement table during the analysis of a component extracted from a sample by the extraction operation in the extraction container set as a last extraction target among the plurality of extraction containers held in the rack. The rack replacement device is configured to execute replacement of the rack on the placement table during the analysis of the component extracted by the extraction operation in the extraction container set as the last extraction target.

Abstract: A gas chromatograph is provided which is capable of effectively reducing the amount consumed of a carrier gas, reducing the time and effort required for an operator to manually set parameters, and preventing damages to a column and a detector due to a setting mistake. In a case where a stop operation for the power supply of the gas chromatograph is performed (Yes in step S101), the flow rate of a carrier gas to be supplied to a sample vaporization chamber is decreased and the temperatures of the column and the detector are sufficiently lowered (steps S102 to S104), and then the power supply of the gas chromatograph is switched over from an ON state to an OFF state (step S106).
