"An Enhanced Tool for the Study of Mechanisms"
Common themes of treatment for ALL techniques via electrode
concentrations.
Mechanistic interpretation using the whole data set.
Easy comparison between experiments including cross-technique.
Accurate assessment of diffusion coefficients, rate constants and
thermodynamic parameters.
Interpretation of ECcat, ECrev and CrevE mechanisms with unequal diffusion
coefficients.
Interpretation of all data at planar, drop and wire electrodes plus thin
electrolyte films.
Kinetic convolutions for simple data treatment of allied homogeneous
reactions.
Unique Laplace plane methods for single pulse CA.
Treatment of all the above in high resistance electrolyte
via software compensation.
"Providing Teaching and Comparison Data"
The CONDESIMTM and CONVOSIMTM software simulate the
Current/Voltage/Time response for all common controlled potential (CV, CA
and pulse methods) and controlled current
techniques (CP, IG) for a wide range
of electrochemical mechanisms. AC modulation techniques including AC
Voltammetry & Impedance Spectroscopy complete the comprehensive
package contained within CONDECONTM |
Welcome
to the CONDECON Home Page
The CONDECONTM ELECTROCHEMICAL PACKAGE contains
CONDESIMTM and CONVOSIMTM Simulation Software AND full opportunities to
treat experimental data from a range of sources via sophisticated
CONVOLUTION Methods and beyond.
CONDESIM uses digital simulation methods while CONVOSIM operates on the
solutions of the diffusional and other equations involved. Each
encompasses a wide range of electrochemical mechanisms at stationary
planar, drop and wire electrode geometries which in the planar case are
extended to extremes of thin strong electrolyte film behaviour.
The simulation software is fully versatile in that ANY controlled
potential/time or current time/profile can be used to emulate for
example the techniques of: -
-
Cyclic Voltammetry (CV)
-
Chronoamperometry
(CA)
-
Chronoamperometry (CP).
This versatility is then extended quite
naturally within CONDECON, for the full range of mechanisms and
geometries, to: -
-
Differential Pulse Voltammetry (DPP)
-
Normal Pulse Voltammetry (NPV)
-
Interrupt Galvanometry (IG)
-
AC Voltammetry (ACCV)
-
Impedance Spectroscopy (IS)
It is important to note that the
latter simulations are constructed exactly as for say CV and do NOT
depend on any perceived equivalent circuit model or indeed on small
modulation potentials.
It is emphasised that CONVOLUTION Methods rely on the solutions of
differential equations for mechanism and geometry combinations but NOT
on the use of any specific technique. All data is included in
convolution treatment and comparisons over variations of technique and
time scales applied are easily made. Input parameters include electrode
details and a speculation as to the mechanism. Treatment then involves a
calculation of electrode concentrations as a function of time and
verification or otherwise of the mechanism and the homogeneous and
heterogeneous parameters employed.
Commonly accepted non-convolution treatments of data are in most cases
merely limiting behaviour of convolution methods and many of these are
still included within CONDECON. Furthermore treatments for initial
voltammetric pulses are treated via the Laplace Plane (LP) to emphasise
the theoretical methods employed.
High resistance electrolytes offer no challenge to convolution methods
whereas for example linear sweep voltammetry cannot retain simple
diagnostic criteria except when 100% hardware compensation is available
or indeed possible!
CONDECON is a versatile tool for the teaching of and familiarization
with electrochemistry AND equally an important laboratory aid to the
treatment of data.
