Automatic Analyzer and Operation Method of Automatic Analyzer

Abstract

Provided are an automatic analyzer and an operation method of an automatic analyzer capable of improving a temperature control state of a measurement system as compared with that in the related art. The automatic analyzer includes a dilution liquid flow path 1033 from a dilution liquid accommodation bottle 1032 to a dilution tank 1010, an internal standard liquid flow path 1043 from an internal standard liquid accommodation bottle 1042 to the dilution tank 1010, a measurement solution aspiration nozzle 1052 from the dilution tank 1010 to an analysis unit 1092, a first temperature control unit 1091 that controls temperatures of the dilution tank 1010, the measurement solution aspiration nozzle 1052, and the analysis unit 1092, a second temperature control unit 1036 that controls a temperature independently of the first temperature control unit 1091 and controls temperatures of the dilution liquid flow path 1033 and the internal standard liquid flow path 1043, and heat insulation mechanisms 1037 and 1095 provided between the first temperature control unit 1091 and the second temperature control unit 1036.
