ABSTRACT:
A titration electrode device for measuring the amount of a species in solution in a test liquid comprises a counter electrode and a generator electrode both in a chamber for receiving a thin layer of test liquid, the two electrodes being located in respective compartments within the chamber such that ionic conduction between the compartments is permitted but diffusion of electrogenerated reagents between the compartments is restricted, the device including reference and sensor electrodes in the chamber.
