ABSTRACT:
When determining an activity of particular predetermined ions in a sample liquid by use of a device for measuring ionic activity including a pair of ion-selective electrodes which are selectively responsive to particular predetermined ions, a pair of spotting holes through which a sample liquid and a reference liquid are respectively supplied to the ion-selective electrodes and a porous bridge which communicates the spotting holes with each other so as to permit the sample liquid and the reference liquid spotted to the spotting holes to electrically contact with each other, for instance, the sample liquid is first spotted to one of the spotting holes of the device for measuring ionic activity with a first spotting tool, and at least one of the first spotting tool and the device for measuring ionic activity is thereafter moved to remove the first spotting tool away from the device for measuring ionic activity. Then the reference liquid is spotted to the other spotting hole of the device for measuring ionic activity with a second spotting tool within a predetermined time after the sample liquid is spotted to the spotting hole.
