摘要

PURPOSE: A device for measuring a plural ion-selective electrodes array adapting applicative ion concentration, a device for testing electrode performance, a method for measuring an ion concentration, and a method for testing an ion-selective electrode performance are provided to compare and analyze the performance of each sensor by mounting various sorts of sensors reacting to specific ions at the same time, thereby efficiently obtaining a sensor development through a performance test of an ion-selective electrode.;CONSTITUTION: A device for measuring a plural ion-selective electrodes array adapting applicative ion concentration comprises buckets(1), a rinse bucket(2), an ion concentration measuring part, a signal converter(6), a receiver(7), a sample solution feeding line(8), a pump(9), a valve(10), a washing liquid feeding line(11), a valve(12), a spinning motor(13), a motor controller(14), and a computer(15). The bucket accommodates the sample solution. The rinse bucket accommodates the washing liquid. The ion concentration measuring part is composed of a plurality of ion-selective electrodes(4) and a reference electrode(5). The signal converter converts analog signals obtained from the ion-selective electrodes of the ion concentration measuring part in to digital signals. The receiver is installed in the lower part of the ion concentration measuring part to be rotated. The sample solution feeding line supplies the sample solution to the receiver side from the bucket.;COPYRIGHT KIPO 2012
