Spectro-EFC Cell Attachment for SPE holder, UV-vis-NIR

This is a multi-purpose Spectro-EFC Cell Attachment designed to be coupled with a light source and spectrometer (UV-vis-NIR) via bifurcated optical fiber. It enables obtaining electrochemical and spectroscopic information from Screen-Printed Electrodes (SPE), where variations in the applied potential to the working electrode induce changes in the observed reflection spectrum.

The applied curved optical collimating lens is to be connected with a bifurcated fiber (not included) which has two fibers side-by-side in the common end and breaks out into two legs (i.e. light source and spectrometer).

Application note

Spectroelectrochemical set is used to study the relation between absorbance/reflectance and electrochemical potential. It enables real-time monitoring of the optical change at the surface of the working electrode. 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 mechanistic pathways of redox processes.

The Spectro-EFC Cell Attachment consists of two main parts: the chamber and the base which is installed on the guide rails of the Screen-Printed Electrode Holder. In the flow mode, the tubing is typically connected to a peristaltic pump, while in the static (stagnant) mode the cell attachment can be filled using a syringe (neither pump nor syringe are included).
