An automatic analyzer which assures uniformity in mixing effects regardless of sample quantity and test item and thus produces analysis results with high repeatability. The automatic analyzer includes a device for adding a conditioning liquid into a reaction chamber so that the quantity of liquid in the reaction chamber becomes a predetermined quantity prior to being mixed. The conditioning liquid may be a diluent or physiological saline as used for dilution of a sample or any other special liquid that adjusts the properties such as viscosity, surface tension, etc. of liquid to be mixed.

Automatic analyzer and the analyzing method using the same

An automatic analyzer includes a status table storing the status of each analysis module and reagent information identifying each reagent, the supply of which is exhausted, and allowing tracking of the status of each analysis module, etc. The automatic analyzer determines, based on the status table, whether and how it can continue current analysis, and stores the determination results in its instruction information table. The instruction information table stores analysis-unit or -module operating information and information to be supplied to the user or operator. The analysis-unit operating information includes instructions for the analysis modules to initiate an analysis in a normal manner, finish an analysis in a normal manner, omit a pre-analysis operation, omit a post-analysis operation, or stop sampling, etc. Further, the reagent information and the analysis module status are updated each time a reagent container is replaced by the operator.

Automatic analyzer

An automatic analyzer, comprising disposable parts such as large quantities of nozzle tips and reaction containers for use in sample analysis inspection, wherein the part rack () holding unused parts is raised from a lowest position to a rack separation station (A) by a lift for supply () and separated so that only the uppermost stacked part rack can remain on the rack separation station, the separated part rack is moved to a part take-out station (B) where parts on the part rack are taken out one by one from a movable holding part (), and, by opening the floor part of the part take-out station (B) after part consumption, the used part rack is allowed to fall down and recovered on the lift () of a recovery lifter (), whereby the supply of an unused part rack on which unused parts are loaded and the recovery of a used part rack can be performed with a compact system configuration.
