I'm having problem with the correct determination of Rct(Resistance to charge transfer) and your value for a Randles Circuit with Waburg impedance. I just find methods with extrapolations. Can I calculate with some mathematical method?
You might find the information from the following file.

Hi Philipi, you should try to fit your spectrum any specific software you want. In this paper I used one that is really useful https://www.researchgate.net/publication/287968025_Multifunctional_Biosensors_Based_on_Peptide-Polyelectrolyte_Conjugates
Article Multifunctional Biosensors Based on Peptide-Polyelectrolyte Conjugates
Thanks a lot everbody! I'll search for some software to help me
You can use EC-Lab software for fitting your data with the Randles circuit.
You can simulate the obtained EIS experimental points with Zview software using equivalent Randle circuit. The diameter of the semicircle gives the value of Rct.
