OPTISCHER, AUTOMATISCHER ANALYSE- UND MESSAPPARAT

摘要

Disclosed is an analyzing apparatus for applying samples and reagents to the surface of a reaction carrier and for optically analyzing each component contained in the various samples. The dispensing of the samples and reagents and the optical detection operation are performed by an optics/dispensing mechanism moved relative to the reaction carrier in two dimensions. The optics/dispensing mechanism is combined with a cleaning apparatus for cleansing reagents and samples from a dispensing needle by means of a rinsing agent and air ejected toward the needle. The apparatus further includes an automatic lifting mechanism for lifting and replacing a cover disposed on the reaction carrier, and is adapted to move the dispensing needle to a position over a nearby reagent/sample holder so that the needle may take up a desired reagent or sample from the holder and transfer it to the surface of the reaction carrier. The apparatus is capable of performing highly accurate analytical measurements fully automatically and in continuous fashion.
