  • Device for separating electrolyte chambers within an electrochemical sensor
    Publication number: 20030047453
    Abstract: The present invention is drawn generally to an improved electrochemical sensor. 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 impregnated with an electrolyte, an essentially fluid impermeable plug for separating the at least two chambers, and a narrow opening through the plug providing a non-axial flow path for ionic communication between the at least two chambers when the electrolyte fluid is present. The invention is also drawn to a reference cell grounding system and method of grounding a reference cell.
