ABSTRACT:
Titration apparatus for measuring chloride electrolyte in blood samples including a pair of coulometric generating electrodes (anode and cathode) for titrating the chloride with silver ions to precipitate silver chloride and a pair of amperometric detecting electrodes for detecting uncombined silver ions following complete titration of the chloride and hence for signaling the endpoint of the chloride titration. A predetermined potential difference is applied across the amperometric electrodes, and an operating condition of zero current flow is established through one of the amperometric electrodes. Current flow between the amperometric electrode and the coulometric anode is monitored to indicate the presence of uncombined silver ions and thereby the titration endpoint.
