This is a horizontally mounted, double-compartment Spectro-Electrosynthesis Flow H-Cell for real-time investigation of compounds synthesised via electrochemical reaction. The cell is compatible with several spectral techniques including UV-Vis (quartz windows), NIR and IR (CaF2 windows), and Ultrafast Laser Spectroscopy (CaF2 windows). The main advantages include a short distance between electrodes (no need for supporting electrolyte), excellent yields due to high surface-to-volume ratio of the electrodes and short reaction time. The cell elements are made of PEEK. It fits aqueous (EPDM/FKM O-Rings) and organic solvent (FFKM O-Rings) electrolyte requirements. The construction is liquid-tight with two separate chambers, each equipped with electrolyte inlet and outlet. Chambers are separated by a membrane so electrochemical products appearing at the CE do not mix with products created at the WE. The membrane may be removed, transforming the cell into a single-compartment reactor.

Application note This cell has been designed for real-time investigation of electro-synthesised compounds. The WE and CE electrodes are symmetrical and mounted in separate compartments with a membrane in between. The thickness of the electrolyte in the detection area is set by one of three spacers (0.3 mm, 0.5 mm and 1 mm). The WE compartment should be connected with an external reservoir to circulate the solvent using peristaltic pumps. Typical applications include electrosynthesis, electro-oxidation and electrofluorination.
