Electrochemical cell
First Claim
1. An electrochemical cell comprising a first electrode pair including a first working electrode and a first counter electrode, and a second electrode pair including a second working electrode and a second counter electrode, with the first working electrode and the first counter electrode facing each other and/or the second working electrode and the second counter electrode facing each other, first working electrode being spaced from the first counter electrode by less than about 500 μ
- m, the first working electrode being spaced from the second counter electrode by more than about 500 μ
m, and the second working electrode being spaced from the second counter electrode by more than about 500 μ

Abstract
The present invention relates to electrochemical cells including a first working electrode 32, a first counter electrode 34, a second working electrode 36, and a second counter electrode 38, wherein the electrodes are spaced such that reaction products from the first counter electrode 34 arrive at the first working electrode 32, and reaction products from the first and second counter electrodes 34, 38 do not reach the second working electrode 36. 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.
