An analyzer including plural stirrers (20, 26, 27) that have plural sound-wave generating elements (23), which are provided on respective vessels holding liquid and generate sound wave toward the liquid, and drive units (22), which drive the sound-wave generating elements, and that stir the liquid using sound wave generated by the sound-wave generating elements; and its abnormality coping method. The analyzer includes a power detecting unit (24) that detects traveling-wave power output from the drive unit and reflected-wave power reflected from the sound-wave generating element; and a control unit (15) that determines whether an abnormality occurs in each of the stirrers on the sound-wave generating element side or on the drive unit side in each of the stirrers based on a reflectivity of the power, and controls the continuation or suspension of an analytical work based on a result of the determination. |
