Title: Automated analytical apparatus and method
Inventor: COHEN BERI
IPC: G01N35/00
Filed: 1990-05-01
Abstract: AUTOMATED ANALYTICAL APPARATUS AND METHOD     ABSTRACT     An automated analytical apparatus and method for performing homogeneous and heterogeneous analysis concurrently and on a random access basis are disclosed.  The apparatus includes a cir-cular reaction tray supporting a multiplicity of peripherally arranged reaction cuvettes, sample handling arrangement for supporting samples to be analyzed and a reagent tray supporting a plurality of liquid-reagent sources.  The individual samples and liquid reagent axe transferred, on a selective-random mode; by appropriate aspirating-dispensing apparatus, respectively, into reaction cuvettes on the reaction tray which are success-ively positioned at a ample and reagent addition stations.  The reaction tray is rotated from the reagent addition station to allow mixing and incubation of the reaction mixture and to posi-tion each cuvette at an analysis station.  In the case of hetero-geneous assays, magnetic particles are introduced into appropri-ate cuvettes at a magnetic particle suspension addition station.      A particle wash station is provided between the magnetic particle suspension addition station and the analysis station whereat, after the reaction, the solid phase is washed in the reaction cuvette to remove unbound materials.  Following such wash sub-strate is added to the reaction cuvette for reaction with the enzyme  solid phase and the magnetizable particles are resus-pended.  The reaction cuvette is then advanced to the analysis station, where the solid phase is withdrawn from the optical path and the appropriate optical readout of the liquid phase is effected. In respect of both heterogeneous and homogeneous assays, the rotational mode of the reaction tray is bidirec-tional, to provide multiple periodic readouts of each cuvette, to obtain data which is processed to provide the rate of the reaction .
