It has been empirically determined that thermoelectric elements that exhibit an increase in AC resistance of about 5% after about 20,000 to about 50,000 temperature cycles will soon fail. When the apparatus is started up or when the operator executes a dedicated self-diagnosis function, the temperature of the heating surface and the cooling surface of the thermoelectric element is made equal, and then the AC resistance is measured to diagnose the failure.
- a thermoelectric element Peltier element
- thermoelectric element thermoelectric element
- temperature adjustment is performed during measurement of the specimen (during the temperature cycle for nucleic acid amplification). If the unit becomes abnormal, it cannot be diagnosed. Further, since the diagnosis is performed based on the increase in resistance caused by fatigue failure of the Peltier element, there is a problem that a failure of components other than the Peltier element cannot be diagnosed in the temperature adjustment unit.

This is because it is possible to reduce variation in results between measurements by always executing the same temperature cycle, and to finish the analysis schedule because it can be completed at the scheduled end time when the nucleic acid amplification process is executed.
- FIG. 6 is a diagram schematically showing an example of the temperature of the temperature control block 1 when the Peltier element 4 is deteriorated and the amount of control signal input to the Peltier element 4.
- the Peltier element deteriorates by repeatedly increasing and decreasing the temperature, the electrical resistance increases and the Joule heat during operation increases. Therefore, heating is advantageous and cooling is disadvantageous compared to the initial state. That is, when the temperature increase / decrease rate is controlled to a certain value, the heating control signal amount at the time of temperature increase is smaller than the initial state, and the cooling control signal amount at the time of temperature decrease is larger than the initial state.
- the heating / cooling control signal amount not only at the time of temperature increase / decrease but also when maintaining a constant temperature changes from the initial value.

- FIG. 7B is a diagram showing a case where the Peltier element 4 is deteriorated, and is a schematic diagram of FIG.
- the amount of heating control signal becomes smaller than the threshold value.
- the cooling control signal amount becomes larger than the threshold value when the temperature is lowered and when the temperature is kept lower than the temperature inside the shielding plate 11.
- the temperature adjustment unit 14 diagnoses that it is abnormal, and further diagnoses that the abnormal part is the Peltier element 4.

- the temperature is recognized to be lower than the actual temperature. That is, the actual temperature of the temperature control block 1 is higher than the set temperature (recognized temperature of the temperature sensor 5). Therefore, the heating control signal amount is larger than the threshold value when maintaining the temperature higher than the temperature inside the shielding plate 11, and the cooling control signal amount becomes smaller than the threshold value when maintaining the temperature lower than the temperature inside the shielding plate 11.

Accordingly, the heating / cooling control signal amount becomes larger than the threshold value at all stages in the temperature cycle.
- the temperature adjustment unit 14 diagnoses that it is abnormal, and further diagnoses that the abnormal part is the heat conduction sheet 13.
- FIG. 7E is a diagram illustrating a case where the tube 10 has not been normally erected. Since the heat capacity of the temperature control block 1 is reduced as compared with the normal time, the Peltier element 4 can maintain the temperature and change the temperature with a smaller output. Therefore, the heating / cooling control signal amount becomes smaller than the threshold value at all stages in the temperature cycle. In such a case, it is diagnosed that the installation state of the tube 10 is abnormal.
- FIG. 8 summarizes the relationship between the amount of heating / cooling control signal input to the Peltier element and the cause of the abnormality identified therefrom.

It can be diagnosed that the performance is abnormal and the atmosphere inside the shielding plate 11 has become high temperature.
- the above-described apparatus diagnosis method can be performed even during nucleic acid amplification, and thus can be diagnosed without providing a special time for diagnosis. However, it can be performed not only during nucleic acid amplification but also during a preparation period in which analysis is awaited after power-on.

- the person performing the analysis starts up the nucleic acid analyzer 32, sets consumables such as specimens, reagents, and tubes, and starts analysis.
- the Peltier element 4 or the like at the stage of starting up the apparatus (that is, the preparation stage of the apparatus immediately after power-on).
- Diagnosis of the temperature adjustment unit 14 including the temperature sensor 5 is started, and if there is an abnormality (failure, performance deterioration), it can be detected early. If an abnormality is detected, the sample can be temporarily stopped and repaired before the sample is pretreated for analysis (mixing of reagents, etc.), so that the risk of wasting the sample can be reduced.
- the apparatus shifts to a normal operation and starts pretreatment for analysis by the nucleic acid extraction unit 33 and the reagent mixing unit 34. Thereafter, even after the nucleic acid amplification step is started, the temperature control unit can be diagnosed at any time because no special operation is required. As a result, when an abnormality is detected, the analysis is immediately stopped, and an erroneous analysis result can be prevented from being displayed. In addition, when the user wants to diagnose the performance of the temperature control unit, it is also possible to execute the diagnosis manually if the analysis operation is not performed after starting up the apparatus.
