PROBLEM TO BE SOLVED: To inexpensively provide a compact sample solution automatic analyzing device which does not cause individual errors by reducing the number of instruments. SOLUTION: The automatic analyzing device includes a sample solution suction part, a plurality of reagent liquid storage tank, an automatic multi-way valve, a three-way valve, sump, proportioning feed pump, cells for analysis, and sensors. The sample solution suction part and the plurality of reagent liquid storage takes are each piped to the automatic multi-way valve, and the automatic multi-way valve is operated to selectively feed solutions from the piping to the three-way valve. The three-way valve is piped to the automatic multi-way valve, proportioning feed pump, and cells for analysis and is operated to collect the solutions from the automatic multi-way valve in the sump once by the action of the proportioning feed pump to inject them into the cells for analysis. The sensors are mounted to the cells for analysis to detect changes caused by the addition of reagents. |
