Potentiostat / galvanostat / EIS

Potentiostats / galvanostats are designed for electrochemical measurement in the field of corrosion coatings, batteries, general electrochemistry and so on. Electrochemical Impedance Spectroscopy (EIS) is available as an option for each instrument. This analysis method is used for studies of corrosion, batteries, photovoltaic systems and in some life science applicationsOther options include a broad selection of voltage and current boosters.

We have a selection of Potentiostat through BioLogic Science Instruments. Our range of products comprises galvanostats with single potentiostats additionally, they can be configured as bipotentiostats and multichannel galvanostats that offer up to 16 channels to take measurements of the electrochemical effects of up to 16 simultaneously.

What exactly is a potentiostat and galvanostat function?

The basic potentiostat utilizes three electrodes (2 or four electrode connections are feasible). It regulates and monitors the voltage difference between a working electrode and a reference one that has a constant power. It monitors the flow of current between the electrode that is working and the counter electrode (that completes the circuit of cells). As a galvanostat instrument controls the current in the cell rather than the cell’s voltage.

The electrode that is used for the working could be a metal on which a reaction occurs or if corrosion is measured it is a sample of the corroded material. In the case of testing batteries, the potentiostat is connected directly to the electrodes of the battery.

Electrochemical Impedance Spectrum (EIS) tests allow the user to assess charge transfer resistance, double layer capacitance and the ohmic resistance.

Why should you use a Potentiostat / galvanostat or EIS?

A potentiostat is essential for studying chemical reactions, e.g. chemical redox reactions. Another reason to use them is for the testing of batteries. Potentiostats also can be used to determine the presence of electrochemically active compounds (e.g. drugs, toxinsand microbes present in solution.

Electrochemical Impedance Spectroscopy (EIS) has many applications. It is used to study corrosion, e.g. in reinforced concrete as well as in batteries, double-layer studies photovoltaic, and solid-state electrochemistry systems.

Our potentiostat / galvanostat / EIS systems

Crucial to the function of a galvanostat or potentiostat and applications like electrochemical spectroscopy is the application. All of our BioLogic instruments are controlled by the extremely multi-faceted EC-Lab(r) software. It can provide a variety of measurement options, including various modes of control, such as loop and wait options for creating a complicated experimental chainThis software is also able to control multiple potentiostats through a single interface view.

A variety of quality indicators will allow users to confirm their EIS experiment, particularly with regards to linearity, non-stationarity and noise.

Furthermore, in contrast to many other systems, It is also possible to  modify on the fly’ i.e. alter the settings of a parameter during the course of an experiment when results aren’t what you expect.

Examples of the applications of potentiostats and galvanostats / EIS

Metal surfaces may be corroded upon contact with a corrosive solution (mostly acidic media). Electrochemical methods can study the behavior of the material when it is submerged in the corrosive solutionPotentiostats / galvanostats are used to investigate the behavior and behaviors of this metalTechniques like e.g., Electrochemical Impedance Spectrum (EIS), Linear Polarization Resistance and Tafel Plot experiments are used to determine the behavior of the metals.

The photovoltaic cell appear everywhere todaySolar energy is important in local, regional and national energy production. To enhance the efficiency of the energy source the research is donePhotovoltaic solar cells ‘ characterization can be done using polarization as well as Electrochemical Impedance Spectroscopy , which permit the user to assess the performance of the cell and determine the model. The role played by electrochemistry within Energy fields is currently a hot subject.

Understanding the kinetics and thermodynamics of reactions that occur at an electrode serves as the main function of the fundamental science of electrochemistryGalvanostat EIS are essential tools in this field. In this instance, DC steady-state methods have been utilized, including: the cyclic voltammetry technique, chronoamperometry chronocoulometry, chronopotentiometry, pulse voltage, square wave voltage as well as other current-potential techniques.
