Electrochemical Impedance Spectroscopy (EIS)
Electrochemical Impedance Spectroscopy (EIS) is an electrochemical technique 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).
Redox Potential
Redox potential (reduction potential of ORP) is an abbreviation for reduction and oxidation potential. A redox potential is the potential value when the reduction and oxidation of a certain metal or other chemical are in balance with each other. Redox potential is measured in Volt (V).
Nernst equation
The Nernst equation is one of the two central equations in electrochemistry. It describes the dependency of an electrode’s potential on its chemical environment.
