Compliance voltage is the voltage available at the counter electrode that can be used to force current to flow and still maintain control of the working electrode voltage. The compliance should be specified in conjunction with a current value: "20V @ 250mA" or "20V @ full rated current". An amplifier's output voltage decreases at higher currents due to the output impedance of the amplifier. The voltage at the counter electrode is needed to force the electrochemical reaction

Potentiostats by their nature are prone to oscillation especially in experiments like cyclic voltammetry where researchers want to minimize the uncompensated resistance in their electrochemical cell. These oscillation problems tend to be most troublesome when the more sensitive current ranges are used and when the cell capacitance is large. Modern potentiostats have several different methods of minimizing oscillation of which two are the ability to control the control ampli

Some of the properties of an ideal reference electrode are as follows it should be reversible and obey the Nernst equation with respect to some species in the electrolyte its potential should be stable with time it does not exhibit hysteresis after passing small currents In 3-electrode electrochemical experiments, the reference electrode holds a vitally important job as a stable "reference point" for the potential of the working electrode (the electrode of interest). It allow

Choosing between potentiostats available in the market today can be very challenging as they often appear to have very similar specifications on paper. This can make it difficult to choose between the different brands. One of the distinguishing differences is in the software used to control your experiments. Many legacy brands have complicated software that doesn't fully utilize all the features of modern operating systems. Admiral Instruments is different. The company was fo
