Electrochemical Methods

The Department of Functional Materials employs electrochemical methods in various areas: generating/measuring of sensor signals and characterizing of sensors.

Concerning electrochemical sensors simple electrochemical methods such as amperometry or potentiometry can directly be used to determine analyte concentrations (e.g. amperometric enzyme electrode or lambda oxygen sensor). Further on, pulse techniques, cyclic voltammetry or impedance spectroscopy can be used, that perturb the test object in a selective way. In this case, the time-dependent response is analyzed.

The department has various potentiostats/galvanostats that can perform all established electrochemical methods. Some are equipped with an additional impedance module so that impedance spectroscopy can be conducted.

These measurement techniques are employed for electrochemical sensors with liquid as well as solid electrolytes (ion conductors).
