Flow systems
Electrochemical flow systems are broadly used in research and applied fields such as environmental, industrial and medical monitoring due to their high sensitivity and low cost. Furthermore, these systems provide not only analytical information but also mechanistic and kinetic information. The use of a flow system also enables the automation of a process and can provide a much needed design flexibility. Another important advantage lies in the combination of reaction-oriented electrochemical flow systems with species-focused spectroscopy to enable a complete analysis of reactions involving multiple electron transfer steps, as well as unstable intermediates.
In view of the limitations of currently available electrochemical flow cells and with the desire to use commercially available electrodes (disk electrodes embedded in an insulting sheath), we aim to design new types of electrochemical and spectroelectrochemical (SEC) flow systems that will rely on flow-through methodology. Our goal is to construct a user friendly and simple to use device that can be easily automated and will utilize a new type of electrode.

We recently designed our first prototype of an electrochemical and spectroelectrochemical flow platform. Finite element method simulations confirm that the hydrodynamic profile within the device is not turbulent, and provides an analytical platform for the investigation of homogenous kinetics, radical lifetimes and reaction mechanisms. The modular “plug and play” configuration of the platform allows one to carry out electrochemistry and spectroscopy individually or simultaneously.
