This device is one of the most important analytical instruments in nanoelectronics laboratories which is used in the analysis of electrochemical cells. This device through a digital system generates required electrochemical processing signals in a three-electrode system. The Working, Reference and Auxiliary electrodes are responsible for fixing and receiving signals. The device also has the ability to do charge and discharge galvanostatic testing, and impedance spectroscopy.
It is used in many applications such as testing of batteries, supercapacitors, biosensors, and cancer diagnosis sensors. The most important modes of operation of this device are voltammetry, and impedance spectroscopy. The device working range in impedance spectroscopy mode is 0.1 Hz to 200 kHz; scan rate in cyclic voltammetry and linear sweep is 0.1 mV/s to 1 V/s; working frequency in differential pulse voltammetry and square wave voltammetry is 0.01 Hz to 1 kHz, and current at galvanostatic charge-discharge is 100 nA to 15 mA. Another feature of this device is ability to apply successive cycles (chronoamperometry).
