Single Channel Potentiostats
Potentiostats control a voltage and measure a resulting current. The Control Amplifier outputs power to the counter electrode (also called auxiliary electrode). A feedback loop is established to control the cell potential between the reference and working electrode. This voltage is measured by the input electrometer, that has a high impedance. This current is then measured between the working and counter electrodes while this potential is maintained at the working electrode and reference electrode.

Counter Electrodes
For a system using a three-electrode potentiostat, we measured current when a potential is applied between the working electrode and the reference electrode. Passage of current through an electrical circuit requires electron transfer reaction between the working electrode and the counter electrode.The main function of the counter electrode is to provide the location of the second electron transfer reaction. Important parameter of the counter electrode is the surface area. It is required (area) large enough to support the current generated for the working electrode. For example, the surface area of the platinum electrode of 5 cm is sufficient to use as an electrode, such as steady-state cyclic voltammetry experiments. However, for generating a high current measurements such as bulk electrolysis, the counter electrode of a larger area is required, as Catalog No.012961 which the length of platinum is 23 cm. This electrode is used for measurement, such as rotating ring disk.

Integrated Potentiostat and Multiplexer
EmStatMUX8
Based upon the EmStat range, there are two types of multiplexers to suit most types of sensor array work. The MUX8 is the most flexible offering the ability to connect arrays made of up to eight working electrodes in two or three electrode cell types and chips sharing a reference electrode and/or counter electrode. The MUX16 is suitable for sensor arrays or chips with sixteen working electrodes all sharing a RE and/or a CE. Both instruments are suitable for laminated layer corrosion analysis.The potentiostat is controlled and powered by USB and is used with PSTrace allowing for simultaneous sampling of each channel at a rate of 25 ms/channel. Standard packaging includes a shielded cable with connections for a working, a counter and a reference electrode by means of 2 mm banana connectors and mini-crocodile clips, a stripped end, Dsub-37 terminated flat cable and a USB cable. To make connections to chips simpler the Connection Terminal is an optional extra providing clearly marked screw terminals to the electrodes and can be directly joined to the ESMUX via their D-Sub connectors.
