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 consists of a polyether ether ketone (PEEK) flow chamber equipped with magnetic mount sample holder (a screw version is available on request), screw mount quartz window holder and two different mini tripods. It well fits aqueous (EPDM 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. This model differs from standard Spectro-EFC cell in sample dimensions, enabling installation of much smaller substrates (10 mm x 10 mm).

Application note
Spectroelectrochemical cell is used to study the relation between absorbance/transmittance and electrochemical potential. It enables real-time monitoring of optical change in electrochromic materials. 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. Please note that copper electric contact from working electrode stays in no contact with an electrolyte.
