Abstract:
1. An automatic analyzer for analyzing at least a first measurement item and a second measurement item different from the first measurement item by making a sample and a reagent react with each other and measuring a reaction result, comprising: at least a first reaction vessel and a second reaction vessel; a plurality of reagent vessels which stores at least a first reagent corresponding to the first measurement item and a second reagent corresponding to the second measurement item and different from the first reagent; a sample dispensing unit configured to execute a dispensing operation which includes an aspiration of a sample and a discharge of a portion of the aspirated sample into the reaction vessels; a reagent dispensing unit configured to execute dispensing operations which include a first aspiration of the first reagent from one of the plurality of reagent vessels, a second aspiration of a second reagent from the other of the plurality of reagent vessels, a first discharge of a portion of the aspirated first reagent into the first reaction vessel and a second discharge of a portion of the aspirated second reagent into the second reaction vessel; a setting unit configured to set at least first and second relationships, the first relationship being between a first dummy amount at the first aspiration and the first measurement item, the second relationship being between a second dummy amount at the second aspiration and the second measurement item, the first dummy amount being an excess amount in addition to an amount of the first reagent required for the first measurement item and the second dummy amount being an excess amount in addition to an amount of the second reagent required for the second measurement item; a controller configured to determine a first amount of the first aspiration of the first reagent including the first dummy amount in accordance with the first relationship and a second amount of the second aspiration of the second reagent including the second dummy amount in accordance with the second relationship, to control the reagent dispensing unit to exert the first aspiration in accordance with the first amount and exert the second aspiration in accordance with the second amount, sequentially; and an analyzing unit configured to measure a first reaction result of the sample and the first reagent in the first reaction vessel and a second reaction result of the sample and the second reagent in the second reaction vessel to analyze specific components of the samples in the first reaction vessel and the second reaction vessel.
