At ZP we are passionate about Electrochemical Impedance Spectroscopy (EIS), in this article we describe features of the Nyquist Plot.

Depressed semicircle behaviour is explained by the ZARC element. The constant phase element (CPE) is one of the most common circuit elements which exists to describe capacitance.
The ZARC element describes the double-layer capacitance and charge transfer at an electrode-electrolyte interface. It is a parallel connection between an ohmic resistor and a constant phase element (CPE).
