Betriebsverfahren für ein automatisches Analysesystem mit ständigem und wahlfreiem Zugriff zur gleichzeitigen Durchführung mehrerer Bestimmungen an einer Vielzahl flüssiger Proben

摘要

The present invention relates to a method of operating an automated, continuous and random access analytical system capable of simultaneously effecting multiple assays in a plurality of liquid samples, comprising the following steps: introducing sample cups, reagent packs, and reaction vessels for performing said assays onto concentric carousels of a front end carousel, the reaction vessels being introduced to an outer carousel; identifying the reagent packs and sample cups; scheduling the assays; aligning the sample cups and reagent packs with a reaction vessel at a kitting station by rotating the respective carousels; kitting a unit dose disposable in a reaction vessel having multiple independent open chambers in accordance with the scheduled assay by transfer of the sample from the sample cup to a reaction vessel chamber and transfer of specific reagents to separate reaction vessel chambers from the reagent pack; transferring the kitted reaction vessel to a process carousel which is maintained under controlled environment conditions; pipetting the sample and various reagents into a reaction well of the reaction vessel, the amounts of reagent, sequencing of transfer and time spacing therebetween being predetermined by assay scheduling; incubating the pipetted sample and reagent mix; identifying and transferring the incubated mixture in the reaction well to one of at least two assay analytical stations; performing an analysis by reading the prepared reaction mixture and calibrating the reading; and recording the resulting assay reading analysis.
