    摘要: An optical detector for carrying out chemical analyses has at least one light source, at least one electric detection unit and at least one measurement cell. One or several optical paths coupled to the measurement cell(s) are formed between the light source(s) and the photoelectric detection unit(s). Separate edge-emitting semiconductor lasers applied on a substrate have been used in the prior art when miniaturising such detection devices arranged in arrays to simultaneously detect a plurality of analytes. The invention provides instead the use of surface-emitting semiconductor lasers as light sources, which have the advantage of being relatively easy to produce and of occupying considerably less space. The process hitherto required to separate the laser from the mother substrate and to glue it on a foreign substrate can be dispensed with in the disclosed detector.

    摘要: A planar, electrochemical sensor having a substrate, conductive strips deposited on the substrate, and a dielectric layer insulating portions of the conductive strips except those portions which define a working electrode and at least one second electrode. The working electrode may be defined by an open printed region of the dielectric, or by a needle-punched or laser-burned hole or opening in the dielectric which exposes a small region of one of the conductive strips. 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 ml. 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.
