Abstract: According to one embodiment, an automatic analyzer comprises a light source, a spectroscope, a photo detection unit, a storage unit, a selection unit, and a calculation unit. The storage unit stores photo detector identifiers related to photo detectors and wavelength band identifiers in association with each other. The selection unit selects a specific photo detector from photo detectors. The specific photo detector corresponds to a specific photo detector identifier associated with a wavelength band identifier of a wavelength band according to a measurement item of a sample. The calculation unit calculates an absorbance related to the measurement item based on a signal from the selected specific photo detector.

Abstract: Disclosed is an automatic analyzer that analyzes a component of a target layer of a test sample separated into a plurality of layers by transferring the component from an installed container, including: a dispensing probe that descends into the target layer and suctions the component; a detecting unit that detects the height of the layer surface of the target layer of the test sample; a calculating unit that calculates the depth from the layer surface of the target layer at which the total content of the component of the target layer reaches a target amount; and a controller that causes the dispensing probe to descend to the depth calculated by the calculating unit and suction the component.

Abstract: Each of nozzles includes a micropore which is used as a channel, and the channel is exposed to the outside in the vicinity of a front end of the nozzle. An arm supports the nozzles so that the front ends of the nozzles are movable in an insertion/extraction direction, in which the front ends are inserted into or extracted from a specimen container, and the front ends of the nozzles are able to be simultaneously located in the specimen container. An arm movement mechanism and a nozzle movement mechanism respectively move the nozzles so as to move any one of the front ends of the nozzles in the insertion/extraction direction. Particularly, the nozzle movement mechanism is able to change a relative positional relationship of the front end of the nozzle movement mechanism with respect to the insertion/extraction direction.
