Claim 0:
1. A method of determining the ratio of the oxidized and reduced forms of a redox couple in solution, said method comprising:
(a) contacting a first stationary working electrode and a first counter electrode to the solution;
(b) contacting a second stationary working electrode and a second counter electrode to the solution;
(c) applying a first potential at the first stationary working electrode relative to the first counter electrode and measuring a first constant current for the first stationary working electrode; and
(d) applying a second potential at the second stationary working electrode relative to the second counter electrode and measuring a second constant current for the second stationary working electrode;
wherein the first and second constant currents have opposite signs; and
wherein the ratio of the absolute values of the first and second constant currents reflects the ratio of the oxidized and reduced forms of the redox couple in solution.
