Abstract
Electrical contact at a defined potential, esp. at the internal face of a membranous electrode which is sensitive to ionic activity, is obtd. by contacting the internal face of the membrane with a mixt. of a viscous substance and a conducting matl., and providing an electrical connection between the mixt. and the exit screened lead of the electrode, the lead being insulated with polyethylene and silver contacts being moulded into the electrode with epoxy resin. System is used for determining the activity or the concn. of ions in soln. by immersion, and provides improved electrical contact and stability w.r.t. temp., mechanical disturbance, etc. The conducting matl. is simple in structure, unlike prior art ion sensitive electrodes.
