Scanning Flow Cell (SFC) is an electrochemical technique, based on the principle of the channel electrode. In an SFC, electrolyte is continuously flowing over a small polycarbonate block which contains two intersecting channels that form an elliptical opening. [1]
SFC utilizes V-formed geometry with a small opening on the bottom (in range of 0.2-1mm diameter) used to establish the contact with sample. The convective flow is sustained also in the non-contact mode of operation that allows easy exchange of the working electrode.[1]
Application
[edit]The SFC is employed for combinatorial and high-throughput electrochemical studies. Due to its non-homogenous flow profile distribution, it is currently used for comparative kinetic studies. SFC is predominantly used for coupling of electrochemical measurements with post analytical techniques like UV-Vis, ICP-MS, ICP-OES etc. This makes possible a direct correlation of electrochemical and spectrometric signal. This methodology was successfully applied for corrosion studies.[2][3]
