There is provided an automatic analysis apparatus including an analysis module configured to perform an analysis operation of a specimen, and a control device configured to control the analysis module. The analysis module includes a light source configured to emit light, a photometer configured to measure the light from the light source, which has passed through a reaction solution obtained by mixing the specimen with a reagent, a photometer temperature sensor configured to measure temperature of the photometer, an environmental temperature sensor installed in a housing of the analysis module and configured to measure an environmental temperature outside the housing, and a heater configured to heat the photometer. The control device is configured to calculate, based on a correlation between a stable temperature of the photometer and the environmental temperature, the stable temperature of the photometer from the environmental temperature measured by the environmental temperature sensor, and to control the heater only for a predetermined period of time using the stable temperature as a target value of the photometer temperature measured by the photometer temperature sensor.

In an automatic analyzer, it is possible to start analysis of a sample with high accuracy in a short time by stabilizing the temperature of a light detection element or a diffraction grating in a short time. The present disclosure proposes an automatic analyzer including: a light source that applies light to a reaction container in which a sample and a reagent are mixed and reacted; a spectroscopic element that disperses light transmitted through the reaction container; a light detection element that detects light dispersed by the spectroscopic element; a fixing member that fixes the light detection element and the spectroscopic element; a measurement chamber that accommodates the spectroscopic element and the light detection element; a heating device installed on the fixing member; a controller that controls the heating device; a temperature sensor support member installed on the fixing member on an inner side of the measurement chamber adjacent to the light detection element; and a measurement chamber internal temperature sensor installed in the temperature sensor support member, in which a thermal time constant from the heating device to the light detection element is in a range of 80% to 120% of a thermal time constant from the heating device to the measurement chamber internal temperature sensor, and the controller controls the heating device such that a temperature detected by the measurement chamber internal temperature sensor becomes a predetermined temperature (see FIG. 2).

To provide an analyzing apparatus and a method of determining an abnormality capable of detecting abnormalities including defects and deterioration of replaceable components based on a potential difference generated between an ion selective electrode and a reference electrode, in an analyzing apparatus that measures a concentration of electrolytes in a sample, a waveform acquisition unit associates the acquired waveforms with each of driving timings, detects a peak of a waveform that appears in temporal vicinity of the driving timing, and calculates a feature amount. Here, the feature amount includes at least one of the electromotive force at the peak or a time period between a time of the driving timing and a time of occurrence of the peak. Then, the waveform analyzing unit determines an abnormality based on the feature amount (refer to Fig. 4).
