The first entry in the sample file is an Analysis Tag. Analysis Tags prevent data from being analyzed by inappropriate analysis GScripts. The tutorial data allows analysis by Impedance.GScript. A… read more →
An EIS software data file is a standard ASCII file. By default it has a .DTA filename extension. You may use other filename extensions, but they are less convenient. The… read more →
The EIS Analysis package provides a GScript to simulate the EIS behavior of an equivalent-circuit model. To get access to this GScript, click Tools>Run Named Script. Choose EIS Model Simulation… read more →
To change the weighting used by either Simplex or Levenberg-Marquardt algorithms, click Options of the script-specific menu and choose one of the weighting options in the Fit Weighting Options frame.… read more →
To normalize your impedance data to the area of your sample, click Options>Units for Impedance/Area Normalized of the script-specific menu. To remove area-normalization, click Options>Units for Impedance/Not Area Normalized of… read more →
This command clears any fits which have been performed on the data. Fits on both the Nyquist and Bode plots are cleared, and any pages which have been added are… read more →
This command performs the Kramers-Kronig Transform (KKT) on your experimental data and displays the result as a Fit on the Bode and Nyquist charts. It also adds a Kramers-Kronig results… read more →
This command subtracts a circuit Element, an equivalent-circuit Model, or an existing experimental EIS Spectrum from your experimental data. After you choose the Subtraction Method, click either the Series Subtract… read more →
Gamry’s EIS Analysis features a simple-to-use automatic EIS model-fitting routine. It is based on the well-known Simplex non-linear least-squares fitting routine. Unlike older fit routines, it does not depend on… read more →
The Fit A Model (Simplex Method) command fits a data set to an equivalent-circuit model on your computer’s disk. The model can be one of the standard models supplied with… read more →
