Abstract
A device is disclosed for determining ion activity in liquid solutions by the use of electrodes over which a cover sheet with an internal capillary bridge promotes ionic migration between the electrodes. The cover sheet is formed of a porous material ribbon encapsulated in a nonporous web. Preferably, the cover sheet is punched at each electrode to provide fluid access holes for receiving drops of liquid solutions.
