Basic Concepts

Potential - PalmSensA potential is nothing other than the voltage or electrical voltage of a specific (liquid) substance.

Origins of electrochemical potentials - PalmSensThis section is a short explanation of the processes that lead to electrochemical potential and thus to corrosion processes.

Redox Potential - PalmSensRedox 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).

Compliance voltage - PalmSensThe compliance voltage is the maximum voltage that can be applied between the working and counter electrode. Another name could be the maximum cell potential.

Capacitive Current - PalmSensUnderstanding capacitive charging current is important for understanding electrochemical experiments, so in this section the origin and equations for capacitive charging current will be explained. Afterwards the effect of capacitive current during Cyclic Voltammetry and Linear Sweep Voltammetry is discussed

Potentiostats: use, compounds, disadvantages and function - PalmSensIn this section the reasons for the three electrode setup of most potentiostats is explained, what the task of each electrode is and what to take into consideration when choosing your counter electrode.
