"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.

CV, CA and CP data can be inputted from a wide range of sources including:-

• Uniscan Instruments PG format

• Princeton Applied Research (PAR)

• CHI format

• BAS/ DIGISIM format

• 2 column and 3 column text files

 

Once data is within CONDECONTM then all treatments, graphical displays etc are common and additionally data can be saved in a single Consistent format equivalent to that used by PAR software  The latter was chosen because of wide familiarity and the complete and informative nature of the parameters saved along with data.

 

CONDECONTM has a separate built in system for saving details of treatment and simulation quite automatically. This extends to a File Log and to a Lab Notes system such that information is common to users of instruments etc.

 

Comparison of data from a range of sources including internally generated simulations via CONDESIMTM and CONVOSIMTM are a key to consistent storage, treatment and graphical display of data within the laboratory.
