Shown here is a family tree that highlights a number of interfacial electrochemical techniques. The specific techniques are shown in red, the experimental conditions are shown in blue, and the analytical signals are shown in green.
At the first level, the tree divides interfacial electrochemical techniques into static techniques and dynamic techniques. In a static technique we do not allow current to pass through the analyte’s solution. Potentiometry, in which we measure the potential of an electrochemical cell under static conditions, is one of the most important quantitative electrochemical methods. Dynamic techniques, in which we allow current to flow through the analyte’s solution, comprise the largest group of interfacial electrochemical experiments.
