Fitting of Equivalent Circuit for Electrochemical Impedance Spectroscopy data using ZView 4 software

ZView 4.0 is the best option for electrochemistry analysis because, unlike later versions, it allows you to use as much data as you need.
In this video, I install the ZView software and demonstrate the steps to fit the EIS data spectrum using ZView 4.0. With this version, you can create Nyquist, Bode frequency, and Bode-phase plots. Additionally, you can export your fitting results.

Nice background music

@@salonimohare6358 Thank you.

Hi. Helpful video. However, I am not able to plot for all the input data. It is only plotting for a range of input values. Are you using a full version of the software? Because I think since mine is a demo version I am not able to plot it. Please suggest a solution.

Very helpful. Thank you

the value of Rs, Rp and CPE displays the one dialogue box and how to fix the Wo and Rf values..

[@prashant_choudhary]

I appreciate your question. You will get Wo and Rf values in the same dialogue box once you add these elements.

i've question, what's a meaning CPE P and CPE T??

[@prashant_choudhary]

Thank you for you query. The CPE (constant phase element) is defined by two values, CPE-T and CPE-P. CPE-T, parameter represents the magnitude of the CPE. It is a measure of the capacitance-like behavior of the element. In the context of impedance, it is often referred to as the pseudocapacitance or the capacitance coefficient. while CPE-P, parameter represents the phase angle of the CPE, which indicates how much the behavior of the CPE deviates from that of a pure capacitor. It ranges between 0 and 1, where 1 corresponds to a pure capacitor (ideal capacitor behavior) and 0 corresponds to a pure resistor (ideal resistor behavior). If CPE-P equals 1 than the equation is identical to that of a capacitor. If CPE-P equals 0.5, a 45 degree line is produced on the Complex-Plane graph. I hope this can help.
