Why Model Voltammetry?įor all its importance, voltammetry is a difficult technique to understand. By performing voltammetry at different scan rates, where the rate of change of the voltage in time is altered, we can observe different system timescales and so different physical phenomena. It illustrates the competition between the rate of electrolysis at the electrode surface and the rate of transport of the reacting chemical species to that surface by diffusion, and it can also yield valuable information of the mechanism and rates of chemical reactions in solution.

Chemical modification of electrode materials can make voltammetry specific to individual biological compounds or toxic gases in a mixture, and it is a cheap technique where advances such as screen-printed electrodes allow for “disposable electrochemistry”.įor design and research, the great virtue of voltammetry is the diversity of information that it provides. Also, voltammetry can be the fundamental mode of operation for a sensor, since the measured current will be linearly dependent on the concentration of the analyte in a well-designed system.

Voltammetry can be valuable for device verification and design because a single scan contains a great deal of information about the chemical and physical behavior of a system. Furthermore, the chemistry of the electrode-electrolyte interface is still not fully understood and is an active field of academic research.

Electroactive surfaces are common to all electrochemical devices, including common energy extraction devices like batteries and fuel cells, as well as electrochemical sensors, such as those used by diabetics to monitor blood glucose concentration. The voltage is swept up and down across a range of values to successively drive the opposite directions of an electrolysis reaction:Ĭyclic voltammetry is a very widely used technique for the interrogation of physics and chemistry at the interface between an electrode and an electrolyte, such as a saline solution. This is a cyclic voltammogram, in which the current (“ammetry”) is plotted against the voltage applied to an electrochemical cell. The “double-peaked” graph looks like this: Somewhere near the front, you’ll see a distinctive “double-peaked” graph. But look at any electrochemical journal, conference proceedings, or company website for manufacturers of electrochemical sensors.

Please use only use COMSOL 4.0a with any software updates added (). Otherwise, I cannot use the file anymore what would be a waste of time. Is there maybe a converter implemented in 3.5a to make the file compatible with lower versions? Then I can ask a friend to back convert it. I tried also with version 3.5 to open the 3.5a, but there is the version conflict. Syntax error in low-level element syntax representation.įatal error during assembly or evaluation I tried to open the file made in 3.5a with 4.0. But unfortunately, my licence was expired and we got a new Version to use (Comsol 4.0). I was running a simulation in Comsol 3.5a. Please use only use COMSOL 4.0a with any software updates added ( If you find any more problems, after that, please contact technical support.
