Abstract
There is disclosed a process for producing a laminar electrode. The method comprises successive superposition of an insulating support, a conductive layer, a stable-potential internal reference element and an ion-selective diaphragm, all of which are protected by a mask which is impermeable to aqueous solutions. A completely tight seal between the mask and the ion-selective diaphragm is formed by casting the diaphragm in the form of a solution containing a binder which dissolves with and intimately mixes with the mask material.
