It has long been known that different electrical circuits can explain EIS data in an equivalent manner. that is, they exhibit identical impedance for all frequencies. Ec-Lab software is provided with a powerful tool for EIS data analysis called Zfit. This tool can perform electrical circuit identification with EIS experimental data files obtained either with Bio-Logic potentiostats/galvanostat or with other systems on the market. In fact, EC-Lab software can import ASCII text files generated by other electrochemical stations and perform efficient EIS fits. The user can choose between two different minimization algorithms. Simplex and Levenberg/Marquardt to achieve the best electrical element values.
