Overview

The program works for the most common electrode geometries including the simulation of thin layer cell experiments and the exact (two-dimensional) simulation of band and disk microelectrodes. Effects such as IR-drop and/or double layer charging can be included in all these simulations. It can simulate Cyclic Voltammetry, Chronoamperometry, Square Wave Voltammetry, and Electrochemical Impedance Spectroscopy

DigiElch Standard

• Fast and accurate simulation of the current response for any user-defined mechanism consisting of charge-transfer steps and first- or second-order chemical reactions.
• 1D simulation of finite and semi-infinite diffusion processes for the most common 1D-electrode geometries, real 2D-simulations of band and disk electrode.
• Inclusion of IR-drop and double layer charging.
• Two different simulation methods - a fast "fixed grid simulator" and a slower “Adaptive Grid Simulator”.
• Simulation of amalgam formation with mercury electrodes.
• Modeling surface adsorption and redox catalysis reactions on electrode surfaces with unprecedented detail.
• Export of the screen display in Windows meta file format.
• Export of simulated current curves and concentration profiles into ASCII-files. Several formatting options which enable the exported data to be imported into third-party presentation software.
• Import of experimental (or re-import of simulated) curves.
• Improved computational efficiency via parallel processing.
• Modeling of termolecular charge transfer reactions such as the proton coupled electron transfer.

DigiElch Professional

Includes all the features of DigiElch Standard, plus a non-linear regression strategy applied to multiple data files simultaneously to determine thermodynamic and kinetic parameters from your experimental data.

DigiElch Reference 600 Module

The optional Reference 600 module adds direct experimental control to DigiElch 7. The experimental setup with DigiElch includes hardware settings for the Reference 600 such as current range, filters and control amplifier bandwidth in addition to experimental details like electrode type, diffusion geometry and chemical species. The files collected in this way are ready for fitting in DigiElch 7 out of the box. They have all the information the simulation requires along with the data. This optional module can be used with either the Standard or Professional version of DigiElch.
