This is a horizontally mounted, multi-purpose spectroelectrochemical cell designed for use with standard UV-Vis or IR spectrometers. It enables obtaining electrochemical and spectroscopic information from liquid samples or thin films in systems where variations in applied potential induce changes in observed spectra. It is perfect for fast prototyping of electrochromic windows and displays where both working and counter thin film electrodes can be characterised. It consists of a polyether ether ketone (PEEK) flow chamber equipped with two screw mount sample/window holders and two different mini tripods. It fits aqueous (FKM O-Rings) and organic solvent (FFKM O-Rings) electrolyte requirements. The cell is designed for use with standard reference electrodes of 6 mm diameter and counter electrodes in rod or helix form with 6 mm diameter and 15 mm active length.

Application note This spectroelectrochemical cell is used to study the relation between external reflectance, normal-to-electrode transmittance/absorbance and electrochemical potential. It enables real-time monitoring of optical change in electrochromic thin film material. It also enables in-situ spectral acquisition for detection, identification and characterisation of short-lived electrochemically-generated species/intermediates, resulting in a detailed investigation of the mechanistic pathways of redox processes.
