Automatic analyzer

An automatic analyzer comprising:

• a reagent disk on which a plurality of reagent containers each containing a reagent used for analyzing a sample are loaded;
• a reaction disk on which a plurality of reaction containers where the sample and the reagent react with each other are arranged;
• a sample dispensing mechanism that dispenses the sample by absorbing the sample by dipping a sample dispensing nozzle into the sample contained in a sample container and discharging the absorbed sample into the reaction container of the reaction disk by using a syringe pump, the sample dispensing mechanism including a pressure sensor provided in a flow path between the syringe pump and the sample dispensing nozzle;
• a reagent dispensing mechanism that dispenses the reagent by absorbing the reagent by dipping a reagent dispensing nozzle into the reagent contained in the reagent container and discharging the absorbed reagent into the reaction container of the reaction disk;
• a reaction measuring unit that measures a reaction from a reaction solution of the sample and the reagent in the reaction container;
• a storage device configured to store a plurality of parameters of the automatic analyzer in association with each of a plurality of stored elevations in which the automatic analyzer is used, the plurality of parameters being optimized for each of the plurality of stored elevations, respectively;
• and
• a processor configured to:
• acquire information of an input elevation at which the automatic analyzer is provided;
• read a parameter of the plurality of parameters stored in the storage device for absorption abnormalities determination and set the read parameter to the automatic analyzer based on the input elevation;
• and
• determine the absorption abnormalities of the sample dispensing nozzle using pressures detected by the pressure sensor and the parameter set to the automatic analyzer,
• wherein at least one of the plurality of parameters of the automatic analyzer stored in association with each of the plurality of stored elevations includes information of a replacement cycle of a component included in the automatic analyzer.
