PURPOSE:To speed up measurement by constructing a dilution cell as two cells and executing the dilution, dispensation and stirring of the next specimen during the measurement in an electrode part. CONSTITUTION:First, the specimen is sucked from a sampling cup on a sample table 2 by a sampling nozzle 61 and is dispensed into the dilution cell 13 where the specimen is stirred; at the same time, the specimen is dispensed into a Cl measuring part 81. The cell 13 is then rotated and the electrode potential of the specimen is measured by the electrode part 16. A reference liquid is dispensed and the electrode potential thereof is measured. The conc. of the specimen is detected by utilizing the data obtd. in such a manner and the calibration curve preliminarily formed in the stage of calibration and is displayed on a display part 5. The two cells are provided for the cell 13 and the dispensation and stirring of the next specimen are executed simultaneously with the measurement by the electrode part 16. |
