Abstract:

The design and performance of an easily constructed spectroelectrochemical cell suitable for batch and flow
injection measurements are described. The cell is fabricated from a commercially available 5-mm quartz
cuvette and employs 60 ppi reticulated vitreous carbon as the working electrode, resulting in a reasonable
compromise between optical sensitivity and thin-layer electrochemical behavior. The spectroelectrochemical
traits of the cell in both batch and flow modes were evaluated using aqueous ferricyanide and compare
favorably to those reported previously for similar cells.
