Abstract:
An analyzer comprises a dispenser which dispenses a liquid into a container, a detector which comprises a phototransmitter which emits light to the container and a photoreceiver which receives light from the phototransmitter, a moving unit which changes a relative position between the container and the detector, and a controller which determines whether an amount of the liquid in the container is within a predetermined range, based on outputs from the detector at a plurality of the relative positions.
