Electrochemical cell
First Claim
1. A hollow electrochemical cell comprising:
- a first working electrode,a first counter electrode, anda second working electrode, in which the first working electrode and the first counter electrode are disposed within a first sample receiving reservoir of the hollow electrochemical cell with the first working electrode being spaced from the first counter electrode by less than about 500 μ
m, wherein the second working electrode is disposed in a second sample receiving reservoir adjacent the first sample receiving reservoir of the hollow electrochemical cell, the second working electrode being spaced from the first counter electrode by more than 500 μ
m wherein the first sample receiving reservoir has a height dimension that is less than 500 μ
m and the second sample receiving reservoir has a height dimension that is greater than 500 μ
m.

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.
