ABSTRACT:
The present invention relates to electrochemical cells including a first working electrode32, a first counter electrode34, a second working electrode36, and a second counter electrode38, wherein the electrodes are spaced such that reaction products from the first counter electrode34arrive at the first working electrode32, and reaction products from the first and second counter electrodes34, 38do not reach the second working electrode36. Also provided is a method of using such electrochemical cells for determining the concentration of a reduced or oxidized form of a redox species with greater accuracy than can be obtained using an electrochemical cell having a single working and counter electrode.
