Electrochemical sensors |
摘要 |
An electrochemical sensor having a substrate, conductive strips deposited on the substrate, and a layer insulating portions of the conductive strips except those portions which define a working electrode and at least one second electrode. A solid electrolyte contacting the electrodes is covered by a semipermeable membrane which may comprise an acrylonitrile butadiene copolymer or an acrylate-based copolymer. A sample chamber is defined by the membrane, a cover member, and a gasket therebetween, and has a volume of from about 1 to about 2 mu L. The gasket is formulated from the highly cross-linked polymerization product of epichlorohydrin. All sensor components are selected such that a sensor operable for at least 2 days under normal conditions is produced.
