For the investigation of redox processes we established several electrochemical techniques in our laboratory which require potentiostats and a range of reaction chambers such as flow-cells, rotating disc (or ring-disk) electrodes, and a quartz crystal microbalance. Sensitive equipment is placed in Faradaic cages to protect them from electromagnetic interferences. We perform

potential sweep methods (e.g. cyclic voltammetry, CV), pulse voltammetry (square wave volammtery, SWV),  amperometry and electrochemical impedance spectroscopy (EIS) to determine the redox potential of enzyme cofactors, electron transfer rates and reaction rates and the electronic polarization behaviour of enzyme modified electrodes.
