Electrochemical Impedance Spectroscopy

Application ID: 14431

Electrochemical impedance spectroscopy (EIS) is a common technique in which a small oscillating perturbation in cell potential is applied to an electrochemical system so as to interrogate the kinetic and transport properties. The Electroanalysis interface is used with a frequency domain study to simulate EIS for a range of electrode reaction rates. Nyquist and Bode plots illustrate the transition between the reaction proceeding under kinetic or transport control.
