Abstract
An analyzer includes plural stirrers that have plural sound-wave generating units, which are provided on respective vessels holding liquid and generate sound wave toward the liquid, and drive units, which drive the plurality of sound-wave generating units, and that stir the liquid using sound wave generated by the sound-wave generating units; a power detecting unit that detects traveling-wave power output from the drive unit and reflected-wave power reflected from the sound-wave generating unit; and a control unit that determines whether an abnormality occurs in each of the stirrers on the sound-wave generating unit side or on the drive unit side in each of the stirrers based on a reflectivity of the power, and controls continuation or suspension of an analytical work based on a result of the determination.
