摘要： A display control unit (52) displays a screen for setting sample information on a display unit (8) for each sample placed in a sample placement section (20), and an input processing unit (53) receives information such as a culture name and seeding date and time information input by an operator via an operation unit (7), and stores the information in a storage unit (55). This file is transferred to a data processing unit (4) and stored in a sample information storage unit (40). After analyzing the respective samples in an LC-MS (3), a quantitative analysis unit (42) performs a quantitative analysis based on the obtained data, associates the analysis result with the sample information, and stores the data in an analysis result storage unit (43). As a result, the sample information and the analysis result of the respective samples in the preprocessing stage are associated with each other. Result display processing unit (44) arranges sample information and an analysis result for one sample on the same screen and displays them on display unit (8). With this display, an operator can easily and accurately grasp the correspondence relationship between the sample information and the analysis result of a plurality of sample to be subjected to preprocessing.

摘要： A system for geochemical characterization of a sample includes a closed reaction chamber configured to perform a high temperature and high-pressure acid digestion test, a spectrometry system configured for performing trace element analysis, and a controller. The controller includes a processor and a memory. The memory includes instructions stored thereon, which, when executed by the processor, cause the system to mineralize the sample based on a microwave process using the closed reaction chamber, and perform trace element analysis on the mineralized sample by the spectrometry system.

摘要： 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.

摘要： The control section of a control apparatus executes a first control for operating a voltage application section such as to cause a current to flow in a first direction through a gas sensor in a first period, and a second control for operating the voltage application section such as to cause a current to flow in a second direction, opposite to the first direction, through the gas sensor in a second period. The control apparatus changes the length of at least one of the first period and the second period based on a comparison between a first measurement value, which is the absolute value of a value measured by a sweep measurement section during execution of the first control, and a second measurement value, which is the absolute value of a value measured by the sweep measurement section during execution of the second control.
