ABSTRACT:
A method for measuring the concentration of glucose diffused from a source to a working electrode which assembly includes a scavenging electrode is disclosed. The electrode of the invention is comprised of 1) a working electrode; 2) a scavenging electrode; 3) an electroosmotic electrode; and 4) a electrically insulating gap defined by adjacent edges of 1) and 2) and electrically isolating 1) and 2). The scavenging electrode substantially reduces or eliminates "edge-effects" or error in signal transported to the working electrode via a path which includes a radial vector component, i.e., eliminates chemical signal other than that which moves to the catalytic surface of the working electrode via a path which is substantially perpendicular to catalytic surface of the working electrode.
