Abstract

PURPOSE: To prevent enlargement of measuring error of subsequent specimens by preventing the response time of ion selective electrode from becoming longer even when the specimen to be measured is not charged, by adding specific diluting liquid in the specimen container.
CONSTITUTION: The additive liquid having the same specific ions as the electrolyte to be analyzed is charged into a speciment container 22 prefilled with a constant volume of serum, from an additive liquid tank 1 through a movable tube 3 by an automatic pipette 2. Specimen containers 21 to 25 are intermittently and successively moved, and a movable tube 9 is inserted at the position of the container 25, so that a constant volume is sucked by an automatic pipetter 10 to be sent into a measuring tank 11. The electromotive force generated from a comparator electrode 13, ion selective electrodes 14, 15 in the tank 11 is led into an amplifier 16, and the concentration of each ion is displayed in a signal display unit 17. At this time, since the electrolyte at the constant concentration is contained in the container 23 in which serum is not sampled due to malfunction, a certain level signal is generated, so that adverse effects may not be applied to the measurements of subsequent specimens.
