Abstract

The object of the invention is to provide an automatic analysis apparatus capable of setting a dispensing mechanism for measuring dispensing accuracy and a dispensing volume, and capable of performing dispensing accuracy measurement without absorbance measurement. Regarding a dispensing accuracy, a dispensing mechanism to be measured is designated. Parameters including a dispensing volume and the like are input. A dispensing operation of the input dispensing volume is automatically performed for each designated dispensing mechanism. A reaction vessel contains, for example, a reagent of the input dispensing volume which has been dispensed by the designated dispensing mechanism. By measuring a weight of the reagent in the reaction vessel, or the like, it is possible to measure the dispensing accuracy of the designated dispensing mechanism.
