Analytical Cells
Flow Cells
In-flow analysis of redox species
Two flow cells are available to mobile species: a cross flow cell and a radial flow cell. The cross flow cell can comprise a single or a dual electrode, while the radial flow cell only comprises a single electrode
Electrochemical flow cells are required when one needs to analyze mobile phases, for example from HPLC (High Performance Liquid Chromatography) or to perform detection of molecules such as hydrogen peroxide, cyano-sulfide, thiol-related compounds, amino acids etc… The use of dual electrodes allows to improve the selectivity. The electrodes are available in different metals so that several molecules can be detected. The redox flow cells allow for a radial or cross flow operation. The cross flow cell is specially designed for microbore chromatography, while the cross flow cell is designed for bio-sensors development.
