This assures that no excessively high or low values of potential are observed throughout the frequency range. The software makes smart decisions about the applied current amplitude to maintain the voltage desired. The operator can control AC current, DC offset current, starting and ending frequencies, and number of data points measured per decade frequency.Ī variable amplitude version of galvanostatic EIS where the operator specifies the maximum allowed AC voltage amplitude. The electrochemical cell is maintained under galvanostatic control. The operator can control AC voltage, DC offset voltage, starting and ending frequencies, and number of data points measured per decade frequency.Īcquires an impedance spectrum over a range of frequencies. The electrochemical cell is maintained under potentiostatic control in either two or three electrode configurations. Microsoft® Windows™ XP SP3/Vista/7/8/10 (32-bit or 64-bit)Īcquires an impedance spectrum over a range of frequencies.Gamry PCI4/Series G, Reference, or Interface Family Instrument.A unique Auto-Fit routine takes the guesswork out of estimating initial values for your model elements.Kramers-Kronig Transform to evaluate the quality of the EIS data.Choice of Levenberg-Marquardt or Simplex algorithms in fitting the data to equivalent circuits.Graphic Model Editor for equivalent circuit models with the ability to define custom components.Realtime monitoring of signal-to-noise ratio for deciding when a measurement is done for the best data in the shortest time.Bode or Nyquist real-time display of spectrum as it develops.Continuous AC amplitude and DC offset correction for the most accurate potential and current measurement!.Bernard Boukamp, University of Twente, The Netherlands).ĮIS applications include coatings evaluation, fuel cell characterization, battery testing, corrosion rate determination, mechanistic and kinetic studies, and more.Ĭheck out our full line of Electrochemical Impedance Spectroscopy application notes. The data files are compatible with ZView 2 (Scribner Associates), ZSimpWin (Ametek), and Equivalent Circuit (Dr. If you prefer to use your own modeling program, we're happy to help. We have used this approach to make transmission line elements in collaboration with researchers from Universidad Jaume I. If you have a unique model, take a look at our User Defined Components Application Note. You can even define your own custom element. Spectra can be fit to standard cell models or custom models created with our graphical Model Editor. The EIS Software allows you to measure impedances spanning 15 orders of magnitude over a frequency range of 10 µHz to 1 MHz!ĭata analysis in the Echem Analyst is easy.
