Abstract
Provided is a specimen dispensing mechanism that includes a specimen nozzle dispensing a specimen to be analyzed in a specimen chamber to a reaction chamber by suctioning and ejecting the specimen, and the specimen dispensing mechanism is controlled so as to perform a specimen suctioning process of inserting the specimen nozzle into the specimen chamber and suctioning the specimen in the specimen chamber, a liquid suctioning process of suctioning a liquid by the specimen nozzle after the specimen suctioning process, and an ejection process of ejecting the liquid and a portion of the specimen to the empty reaction chamber from the specimen nozzle in this order. Thereby, it is possible to provide an automatic analyser and a method which are capable of dispensing a small amount of specimen with a high level of accuracy, without depending on the outer shape of a specimen nozzle or the viscosity of the specimen.
