摘要： An apparatus for measuring ionic activity has a nozzle connected to a reservoir containing a reference solution. The reference solution is pumped up from the reservoir without coming into contact with air, so as to be quantitatively dripped through the nozzle when a slide-type ionic activity measuring device is located at a position below the nozzle. After the reference and sample solutions are spotted on the ionic activity measuring device, at least one pair of probes comes into contact with the device so as to measure potential difference corresponding to ionic activity difference of at least one ion between the reference and sample solutions.
