DigiElch is a Win32 program that computes the
electrical current and the concentration profiles
for any user-defined mechanism comprising an
arbitrary number of charge transfer steps and
first- or second-order chemical reactions. The
program works for the most common electrode
geometries including the simulation of thin layer
cell experiments and the exact (two-dimensional)
simulation of the electrical current response at
band and disk microelectrodes. Effects such as
IR-drop and/or double layer charging can be
included in all these simulations.
The basic module of the program includes only a
simulator for cyclic voltammetry. However, the
functionality can be extended by purchasing
licenses for extension modules, for instance
those for chrono-amperometry or square-wave
voltammetry. Real experimental current curves
(stored as U/I- or t/I-couples in ASCII-files)
can be imported into DigiElch and compared with
simulated ones. The determination of
thermodynamic and kinetic parameters involved in
the underlying reaction scheme can be
accomplished in this way either by "trial and
error" (DigiElch - Standard) or by making use of
the non-linear fitting procedure implemented into
DigiElch - Professional.
