Abstract
A device is disclosed for determining the ionic analyte activity in liquids, e.g. aqueous solutions, by the use of electrodes and an internal capillary bridge which promotes ionic migration between the electrodes. This device includes an electrically insulative frame in which the electrodes are mounted, liquid access holes aligned with the electrodes on a capillary bridge formed of a porous material, and a cover sheet element formed of a nonporous cover sheet. The cover sheet element extends over the electrodes and encapsulates the elongated capillary bridge. Located in the cover sheet directly over and generally along the capillary bridge is one or more substantially continuous stretch lines typically provided by mechanically deforming the cover sheet. This deformation allows shorter junction times when liquids are introduced into the liquid access holes.
