Abstract
Provided is an automatic analysis device and an analysis method which are capable of reliably detecting an abnormality in a dispensing amount of a solution such as a specimen or a reagent to be dispensed and suppressing a decrease in analysis accuracy. Included are a specimen dispensing mechanism 113 that dispenses an analysis target specimen in a reaction vessel 116, a reagent dispensing mechanism 123 that dispenses another dispensing object different from the specimen in the reaction vessel 116, and a mass analyzing unit 133 that detects and analyzes a specific component in a reaction solution in which a specimen dispensed into the reaction vessel 116 and another dispensing object are mixed to each other, in which it is determined whether a dispensed liquid amount of the another dispensing object is abnormal or not, based on a detection result of a standard substance for dispensing inspection which has been added in advance to the another dispensing object, which is detected at the same time with the detection of the analysis target component of the specimen in the reaction solution in the mass analyzing unit 133.
