What’s important in the selection of a potentiostat? That depends greatly on its intended use. This page addresses an often misunderstood term. Compliance voltage Compliance voltage is the voltage available at the counter electrode that can be used to force
My favorite My favorite reference electrode is the Ag/AgCl reference.electrode. Due to its simplicity, it is quite robust, and can be easily and effectively ‘revived’ if it should dry out. Moderately high temperatures ( 100 °C ) can be tolerated,

A Common Potentiostat Design This style of I/E Converter is well suited to potentiostats with output currents of a few tenths of an ampere up to several amperes. This scheme has been used by Gamry, PAR, Solartron, and perhaps others.
Introduction This Application Note presumes that you have a basic understanding of potentiostat operation. If you are not that knowledgeable concerning electrochemical instrumentation, please read Potentiostat Fundamentals before continuing. Experienced potentiostat users may skip the primer and read on. It’s
Introduction A potentiostat is an electronic instrument that controls the voltage difference between a Working Electrode and a Reference Electrode. Both electrodes are contained in an electrochemical cell. The potentiostat implements this control by injecting current into the cell through
Often we find a potential listed in the literature quoted against a different reference electrode than the one we favor, or we would like to convert the potential to a more commonly used reference electrode for publication. A student emailed
The following tables give the potentials of several commonly used reference electrodes. Various filling solutions are listed where data was available. Note that the nature and concentration of the filling solution can dramatically change the potential! When you look through
