ABSTRACT:
An analyzer for ionic activity measurement comprises a device supporting base provided with a liquid feeding section for feeding a reference solution in drops to one electrode of an ion selective electrode pair of an ionic activity measuring device and feeding a sample solution in drops to the other thereof, a potential difference measuring section, and a device ejecting section for ejecting the measuring device. A device holder is disposed for holding the measuring device on the device supporting base. A holder movement mechanism moves the device holder for transferring the measuring device sequentially to the respective sections of the device supporting base. A probe movement mechanism is interlocked with the holder movement mechanism for making potential difference measuring probes contact with the electrodes when the measuring device has been transferred to the potential difference measuring section of the device supporting base, and moving the probes away from the electrodes before the measuring device is moved out of the potential difference measuring section.
