DEVICE FOR SEPARATING ELECTROLYTE CHAMBERS WITHIN AN ELECTROCHEMICAL SENSOR

摘要

The present invention is drawn generally to an improved electrochemical sens or (10). The reference cell within the sensor can be a salt bridge comprising a t least two chambers for containing an electrolyte fluid, preferably containin g a semipermeable plug (22) impregnated with an electrolyte, an essentially fluid impermeable plug (38) for separating the at least two chambers, and a narrow opening through the plug providing a non-axial flow path (50) for ion ic communication between the at least two chambers when the electrolyte fluid i s present.
