Cell with reusable and disposable assemblies for simultaneous electrochemical and EPR measurements

摘要

A cell and method for simultaneous electrochemical and EPR measurements, including a disposable assembly, allows for a single device to produce data for both electroanalysis and EPR spectroscopy by generating a Redox reaction to form free radicals. The cell includes first and second hollow tubes, with the second tube being removably insertable into the first hollow tube. The interior of the first tube contains an insulating material, an electro-conductive material, and a wire connector extending from the electro-conductive material and out the first tube. The interior of the second tube contains an electrolytic solution, an analyte, a working electrode, and insulating material surrounding the working electrode. The second tube is inserted into the first tube and a reference electrode is placed into the second tube. The cell is placed within an EPR spectrometer. A potential is applied to the reference electrode to generate the Redox reaction of the analyte.
