RelaxIS. Versatile software for analyses in electrochemical impedance spectroscopy
Get inspired by RelaxIS – our proven stand-alone software for analysing electrochemical impedance spectroscopy measurements. It is compatible with most major-brand analyser data formats. Optimised for working with many spectra at a time, RelaxIS’ analysis functions can be applied quickly to a full measurement series.
- Compatible with practically all EIS analysers
- Offers both common and advanced analysis techniques
- Customisable in many areas with a powerful plug-in system
- Available for Microsoft Windows 10 / 11
Your advantages using RelaxIS
- Save valuable time by quickly importing data without prior export
- Fully customisable, publication-ready plots
- Practical Auto-Fit function to get great fits without much hassle
- Outstanding DRT calculation and DRT visualisation features
- The full analysis workflow of import, analysis, results investigation and export – combined in one software
- Extensive customisability via RelaxIS 3 plug-ins
Selected RelaxIS 3 highlights
Powerful Auto-Fit
With the Auto-Fit function, you can fit any model to a spectrum – in seconds and without parameter initialisation. A true one-click fit!
Easy data import
RelaxIS supports many file formats produced by various analyser manufacturers. So you can import your files directly without the need for a prior text export.
Also benefit from customisable text file import to load multiple spectra simultaneously from one file – including metadata like temperature or voltage if available.
Flexible data visualization
The visualisation of impedance spectra is an important, but often overlooked aspect of data analysis. RelaxIS offers a multitude of ways to look at your data, i.e. freely customisable Nyquist- or Bode-, overlay- and 3D-plots. You can even use live-analysis views like DRT or KK that shows quick calculations while browsing the data.
You don’t just measure one spectrum, right?
RelaxIS is based on the idea of handling large measurement series. This means that you can analyse many spectra in batches – be it with fitting, DRT calculation or exports. Also further analyses of measurement series are possible, e.g. by Arrhenius-Fits directly in RelaxIS.
