An improved potentiostat/electrochemical cell system with low levels of extraneous electronic noise includes two working electrodes that are maintained at the same potential. With this system the random noise generated at the metal/electrolyte interface in an electrochemical cell can be isolated for study from the random noise generated in other regions of the cell and from the random noise generated in associated electronic circuitry. The difference between the currents to two virtually identical working electrodes poised to the same potential is monitored, resulting in the cancellation of coherent current components.
