What is a potentiostat?
A potentiostat is an analytical instrument that controls the voltage difference between a working eectrode(WE) and a reference electrode(RE). In almost all applications, the potentiostat measures the current flow between the working and counter electrodes. The controlled variable in a potentiostat is the cell potential and the measured variable is the cell current. When we say potentiostat, it’s also galvanostat or electrochemical workstation. It consists of a potentiostat that controls the voltage across an electrochemical cell, and a galvanostat that controls the current through the cell. It is widely used to study electrochemical reactions in corrosion, electrodeposition, battery testing, sensor, eletrocatalysis etc.

Application of EIS potentiostat CS310M
Corrosion: EIS potentiostat CS310M includes all the electrochemical techniques for corrosion measurement such as OCP, polarization curve (potentiodynamic), EIS, Cyclic polarization CPP (passivation curve), Electrochemical Potentiokinetic Reactivation (EPR), Hydrogen diffusion test, ZRA, Electrochemical noise, etc. It can be used to study metal corrosion mechanism and corrosion resistance, and evaluate the coating durability and sacrificial anode current efficiency. It can also be used for rapid screening of corrosion inhibitors, fungicides, etc.

Electro-catalysis
● EIS potentiostat CS310M can measure the half-wave
potential (ORR), overpotential (HER, OER) of the catalyst, and has the function of peak power density and energy density calculation.
● Long-term cyclic measurement for ORR, OER, HER,
CO2RR by techniques such as cyclic voltammetry,
potentiostatic, galvanostatic. Faraday efficiency can be
measured with a bipotentiostat.
● Maximum current can be 20A and compliance voltage can be 30V, and with IR compensation technique,
Corrtest potentiostat can precisely measure the overpotential of the electrode, which is a big advantage in electrocatalysis field.
