Two, Three and Four Electrode Experiments
Electrochemical experiments range from simple potentiostatic (chronoamperometry), to cyclic voltammetry (potentiodynamic), to complex AC techniques such as impedance spectroscopy.
Some of the notes below cover potentiostats in general and others are for Gamry Instruments systems specifically. Click on a link below to download the PDF version of the Application or Technical Note.

Electrochemical experiments range from simple potentiostatic (chronoamperometry), to cyclic voltammetry (potentiodynamic), to complex AC techniques such as impedance spectroscopy.
This Technical Note is meant to show users how the Dual Electrometer feature of the Interface 5000 potentiostat can help you make simultaneous measurements on both half cells during an electrochemical experiment
Of all the components of a Gamry system, the cell cable is the one that is constantly being flexed and exposed to corrosive environments.
The Calibration Cell is a printed-circuit board used for calibration and troubleshooting of your Gamry Instruments potentiostat, and is supplied with every Gamry Instruments potentiostat. Each potentiostat also comes with an AC dummy cell.
What factors limit the speed of pulsing for your potentiostat?
The individual conductors in the cell cable of the potentiostat are made up of coaxial cables. The outer conductor in a coaxial cable is used to shield the signal of interest
In Faraday’s studies and experiments regarding charge, magnetism, and their interaction, he found that charge on a conductor only resided on the outer surface.
The EIS Box is a value-oriented, research-grade electrochemical instrument packaged in a small case. It is designed for battery-testing via electrochemical impedance spectroscopy up to eight cells.
Cell cables are an integral part of your potentiostat and can have a large effect on full measurement capabilities of the complete system.
Since the mid-20th century, rotating disk electrodes (RDEs) have been used to provide a steady stream of reactants “uniformly accessible” to the surface of a disk.
