We are excited to announce the release of EIS Analyzer – our new professional software for Electrochemical Impedance Spectroscopy analysis. This powerful tool is now available as part of the Batalyse software suite and is included at no additional cost for Data Analysis customers.

Key Features

Equivalent Circuit Fitting

Fit your EIS data to 14+ built-in circuit models including R, R-C, R-RC, R-RQ, R-RC-RC, R-RQ-RQ, Randles, and models with Warburg diffusion elements. Need something specific? Define your own custom circuit configurations.

DRT Analysis

Distribution of Relaxation Times analysis identifies time constants and automatically recommends optimal circuit models for your data.

Kramers-Kronig Validation

Verify measurement quality by detecting drift, noise, or non-linear behavior before analysis. Ensure reliable fitting results with automatic data validation.

Multiple Data Sources

Import EIS data from Gamry (.DTA), Solartron (.z), Bio-Logic (.mpr), or text formats (.txt, .dat, .csv, .mpt). Connect directly to databases or Batalyse Collect.

One-Click Automated Analysis

Run DRT analysis, circuit fitting, validation, and predictions simultaneously. Export results as JSON, CSV, or PNG – or upload directly to Collect.

Batch Processing

Multi-threaded parallel analysis for processing multiple files simultaneously.
