Impedance Spectroscopy Overview

The NuVant EZware-EIS software package activates Electrochemical Impedance Spectroscopy on the EZstat-Pro, Powerstat-05 and -20 potentiostat/galvanostats. EZware-EIS exports the impedance data to a file format to accommodate free third party EIS analysis software. EZware-EIS is a user-friendly interface that allows selection of the proper scanning parameters, collect the impedance spectra, display data in Nyquist and/or Bode plots and export data in the proper data format for use in EIS analysis software.
