DEVICE FOR SEPARATING ELECTROLYTE CHAMBERS WITHIN AN ELECTROCHEMICAL SENSOR

摘要

The present invention is drawn generally to an improved electrochemical sensor (10). The reference cell within the sensor can be a salt bridge comprising at least two chambers for containing an electrolyte fluid, preferably containing 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 ionic communication between the at least two chambers when the electrolyte fluid is present.
