Raman EC Flow Cell Attachment for SPE holder

This setup combines electrochemistry using Screen-Printed Electrodes and Raman spectroscopy, to obtain in-situ chemical information about the reactions taking place during an electrochemical experiment. During an experiment the Raman laser is focused onto the surface of a thin film working electrode through a transparent Sapphire (or quartz) window and thin layer of electrolyte (total optical path of 3 mm). The electrolyte thickness of 2 mm ensures free diffusion of ions.

The assembled set consists of Screen-Printed Electrode Holder, Raman EC Flow Cell Attachment, and the reservoir. The reservoir is composed of a Basic Electrochemical Cell (BEC 50 mL) with two additional plugs. It enables further analysis of the solution or conducting reference electrochemical measurements using classical electrodes (6 mm dia., not included).

The attachment elements are constructed with materials that are chemically resistive to a wide range of electrolytes (PEEK, PFA/ETFE). Other materials such as PTFE, Titanium, Stainless Steel, etc., are available on request. The Flow Cell Attachment well fits aqueous (EPDM O-Rings) and organic solvent (FFKM O-Rings) electrolyte requirements.

Application note

This cell can be used to track kinetic phenomena such as near-surface proton concentration changes during oxidation and reduction reactions at the working electrode. It can also be used to identify materials such as carbon, metal oxides, polymers, and electrolytes, and to determine their structure and distribution. The Raman EC Flow Cell Attachment is installed on the guide rails of the Screen-Printed Electrode Holder. The tubing is connected to a peristaltic pump (not included) which drives the fluid from the reservoir through the cell and then returns it to the reservoir.
