Abstract: A plurality of cartridges each have a specimen tub, a dilution tub and three reaction tubs, and a specimen is placed in the specimen tub in advance. The cartridges are mounted in a rack and set to a cartridge standby section. A specimen dispensing unit distributes the specimen from the specimen tub to the reaction tubs of each cartridge set to the cartridge standby section. Thereafter the cartridges are successively transported independently of one another in selected directions within a three-dimensional space to a first reagent dispensing section, a first reaction path, a second dispensing section, a second reaction path, an unreacted component removing section, a luminescent reagent dispensing section and a hydrogen peroxide dispensing section in the stated order by transport mechanisms provided in the respective sections. Examination processes are carried out with reagents dispensed by reagent dispensing units and through B/F separation by unreacted component removing units. Finally, reaction mixtures are subjected to photometry by a photometric unit in a photometric section, and thereafter the cartridges are transported to a cartridge discharge section. Where an analytical curve correction is effected, a specimen dispensing unit and each of sample cartridges holding sample specimens are moved relative to each other. For example, a first sample specimen placed in the specimen tub of the first sample cartridge is distributed to a first reaction tub of each of three sample cartridges. A second sample specimen placed in the specimen tub of the second sample cartridge is distributed to the second and third reaction tubs of each sample cartridge. A third sample specimen placed in the specimen tub of the third sample cartridge is distributed similarly. The respective sample cartridges are subjected to the examination processes prior to cartridges holding specimens to be examined. A new analytical curve is obtained from the results of examination thereof for use in examining the specimens placed in the cartridges subsequently transported for the examination processes.

Abstract: PURPOSE:To obtain a miniaturized automatic analyzer by reducing analysis processing time, achieving universal property for analysis items, and facilitating an emergency processing interrupt. CONSTITUTION:A specimen is placed into a specimen bath of a cartridge 30 where the specimen bath, a dilution bath, and three reaction baths are formed in one piece and then the specimen bath is set to a cartridge standby part 11. The set cartridge 30 is carried to a first reagent dispensing part 12, a first reaction path 13, a second reagent dispensing part 14, a second reaction path 15, a non-reaction component elimination part 16, a luminous reagent dispensing part 17, and a hydrogen peroxide dispensing part 18 by each carrier mechanism and a reagent is dispensed or is subjected to B/F separation, etc., by a reagent dispensing unit 50 and a non-reaction component eliminating unit 60. Finally, a reaction liquid is subjected to photometry by a photometry unit 70 at a photometry part 90 and then is carried to a cartridge delivery part 20. On the other hand, the photometry result is output from an output device 24.
