ELECTROCHEMICAL FLOW CELL AND ULTRAMICROELECTRODE

摘要

An electrochemical flow cell is described which includes a flow passage extending between the inlet and outlet to define a flow path for fluid to flow through the cell body as fully developed laminar flow. A number of flow-through electrodes are disposed within the flow passage. The flow-through electrodes are arranged in serial flow succession within the flow passage and have a plurality of apertures therein through which the fluid passes. The working electrode is positioned within the flow passage at a predetermined distance downstream of the inlet of the cell body which corresponds to a streamwise location at which substantially fully developed laminar flow occurs. At least the working electrode of the flow cell may comprise an ultramicroelectrode that is manufactured as described herein. However, this ultramicroelectrode, whether single or multicore, may also be used for applications other than the described flow cell.
