This chapter is the first part of the series ‘Cyclic Voltammetry – the Most Used Technique’. This introductory chapter goes into detail on cyclic voltammograms.
Cyclic Voltammetry 1/4- Introduction
Moving from passive potentiometric experiments to potentiostatic experiments by controlling the potential was an important development. However, the step that followed towards potentiodynamic experiments may have been even more important for modern electrochemistry. Potentiodynamic experiments made it easy to collect all the data needed for a plot of current I versus potential E. These plots are called a voltammogram and the technique used for measuring is called voltammetry. In a short period of time the cyclic voltammetry (CV) provides a lot of information and allows kinetic investigations. It is by far the most used technique by PalmSens customers. Experienced electrochemists read quite some information from the shape of a CV.
The Cottrell Experiment and Diffusion Limitation – PDF
This PDF provides the instructions for the experiment related to the article series 'The Cottrell Experiment and Diffusion Limitation'. Have fun!
Voltammogram
A voltammogram is a graph that can be drawn after an electrochemical experiment. This graph has a typical, recognizable form in which the electron flow (current: i) is measured in Volt against the potential (E).
Frequency response analyzer
Nowadays, potentiostats are usually equipped with a frequency response analyzer so that you only need one device for the entire experimental setup. If you need a frequency response analyzer, the purchase of a PalmSens4 portable potentiostat is your best choice.
Electrochemical Impedance Spectroscopy (EIS)
Electrochemical Impedance Spectroscopy (EIS) is an electrochemical techniques to measure the impedance of a system in dependence of the AC potentials frequency.
Cyclic voltammetry
Cyclic voltammetry is a known method of demonstrating the presence of a substance in a given liquid by drawing a graph with a characteristic wavy line. The graph has a typical, recognizable form in which the electron flow (current: i) is measured in Volt against the potential (E).
Anodic Stripping Voltammetry
Anodic Stripping Voltammetry is a method to demonstrate the presence of multiple metals in water. This method is usually applied to investigate the water quality of sewage, surface or drinking water.
Electrochemical Impedance Spectroscopy
In this section the basics of Electrochemical Impedance Spectroscopy (EIS) are explained, i.e. the excitation and the signal as well as the recorded values.
