Abstract

Chemical analysis apparatus for inserting a sample serving as an analyzable substance and a reagent into a reaction container and agitating by irradiating sound waves to the reaction container, the chemical analysis apparatus including: a piezoelectric element generating sound waves; and a driver for driving the piezoelectric element, and including: a wave form producing device for producing an oscillation waveform having a fundamental frequency of the sound waves to be irradiated; an auxiliary waveform producing device for producing an oscillation wave form having a frequency lower than that of the oscillation waveform; a multiplying circuit creating a multiplied waveform between the waveform and the wave form; and, a power amplifier for power-amplifying the multiplied waveform, wherein it is intermittently irradiated with the sound wave in the reaction container, and further, the wave form producing device has a function capable of frequency-modulation with a prescribed frequency width.
