Abstract:
1. An analyzer comprising: a plurality of a sound-wave generating units, wherein each of the sound-wave generating units is provided on a vessel that can hold a liquid, and wherein each of the sound-wave generating unit generates a sound wave toward the liquid that stirs the liquid; a plurality of stirring units, each of the stirring units comprising: wherein the drive unit comprises a power source and drives the sound-wave generating units, wherein the power detecting unit detects a traveling-wave power output from the power source and a reflected-wave power reflected from the sound-wave generating units, wherein the number of the sound-wave generating units is greater than the number of the stirring units, and wherein the sound-wave generating units and the drive units make up a plurality of stirrers, each stirrer being one drive unit and one sound-wave generating unit; a control unit that makes a power abnormality determination on whether an abnormality occurs in each of the plurality of stirrers from a drive unit or from a sound-wave generating unit, wherein the power abnormality determination is based on a ratio between the traveling-wave power and the reflected wave power, and wherein the control unit sets a continuation or a suspension of an analytical work based on the power abnormality determination; and a temperature detecting unit that detects a temperature of the liquid, wherein the control unit makes a temperature abnormality determination on whether an abnormality occurs in each of the plurality of stirrers from a drive unit or from a sound-wave generating unit, wherein the temperature abnormality determination is based on a change in temperature of the liquid before and after being stirred, wherein the control unit sets a continuation or a suspension of an analytical work based on the temperature abnormality determination.
