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

Application note

This spectroelectrochemical cell is used to study the relation between external reflectance, normal to the 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 characterization of short-lived electrochemically-generated species/intermediates, resulting in a detailed investigation of the mechanistic pathways of redox processes.
