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.
摘要:
A reaction vessel suitable for multiple assay utilization within an automated, continuous and random access analytical system which allows for kitting of sample and reagents and physical transfer of the kitted reaction vessel to a process carousel is disclosed. The reaction vessel comprises multiple wells of various volume capacities, the multiple wells having openings on the same plane and depths extending from said plane. The reaction vessel has at least one cuvette, which extends substantially below the multiple wells and has an opening on the same plane as the multiple wells. The reaction vessel further comprises a transfer projection on a well bottom portion of the well on a first end portion of the reaction vessel, the cuvette projecting downward from a second end portion of the reaction vessel.

The present invention relates to a method for simultaneously performing at least two assays, said assays comprising a plurality of activities, for a plurality of liquid samples on a continuous analytical system, said method comprising the steps of: combining an aliquot of a first liquid sample with at least one reagent in a first reaction container to form a first assay reaction mixture for said first liquid sample; combining an aliquot of a second liquid sample with at least one reagent in a second reaction container to form a second assay reaction mixture for said second liquid sample; incubating said first and said second assay reaction mixtures at least one time; performing activities associated with each assay other than said combining and said incubating on the first and second assay reaction mixtures to complete each assay, said other activities including analyzing the incubated assay reaction mixtures; and scheduling the steps of said combining, said incubating, and said performing activities other than said combining and said incubating associated with each of the assays according to a predetermined protocol, said protocol specifying: (a) what activities are to be performed for a given assay; (b) an order in which said activities of (a) are to be performed; (c) at least one incubation period between said activities of (a), said at least one incubation period comprising a nominal period of time for the performance of an incubating step between activities of (a) and a specified window of time for varying the duration of the nominal period between activities of (a) to optimize performance; (d) how said activities of (a) are to be performed; and (e) duration of said activities of (a).
