  • Patent number: 12123884
    Abstract: An automatic analyzer is capable of normally maintaining a device condition and exhibiting a stable performance by automatically monitoring a cleaning implementation situation using a wash rack. The automatic analyzer includes an analysis unit, a rack loading unit into which at least a sample rack that holds the sample and a wash rack that holds a cleaning liquid are loaded. A transportation mechanism transports the sample rack and the wash rack to the analysis unit. A management control unit causes the wash rack to be transported to an analysis unit, causes a cleaning operation of the analysis unit by the cleaning liquid held by the wash rack, and causes stopping of the sample analysis operation of the analysis unit to which the wash rack has been transported until a performance of the analysis unit is determined to be normal based on the cleaning operation.
