Zusammenfassung: | To provide an autoanalyzer that constantly maintains the quality of pure water supplied to an analysis unit to a certain level or higher, while reducing operation cost.SOLUTION: An autoanalyzer has a water tank 102, a water level sensor 103 that detects the water level in the water tank, an analysis unit 105 that performs analysis of a specimen; and a control unit 109 that controls water supply and drainage of the water tank. The control unit measures the elapsed time from when the water tank becomes full. When the elapsed time reaches a predetermined retention time limit, if the water level in the water tank detected by the water level sensor is less than a first water level B, the control unit supplies the pure water until the water tank becomes full, and if the water level in the water tank detected by the water level sensor is equal to or more than the first water level and the analysis unit performs analysis of the specimen, causes the analysis unit to continue the analysis of the specimen.SELECTED DRAWING: Figure 8
【課題】運用コストを抑えつつ、分析部に給水する純水の質を常に一定以上に保つ自動分析装置を提供する。【解決手段】給水タンク102と、給水タンクの水位を検出する水位センサ103と、検体の分析を行う分析部105と、給水タンクの給排水を制御する制御装置109とを有し、制御装置は、給水タンクが満水状態になってからの経過時間を計測し、経過時間があらかじめ定めた滞留制限時間に達したとき、水位センサより検出される給水タンクの水位が第1の水位Bに満たない場合には、給水タンクが満水状態になるまで純水を給水し、水位センサより検出される給水タンクの水位が第1の水位以上であり、かつ分析部が検体の分析を行っている場合には、分析部における当該検体の分析を継続させる。【選択図】図8 |
