We're aiming at realization of a spectroscopic measurement for minute amount suspension in the collection site. The proposed method generates a ultrasonic standing wave by the oscillator (diameter: 30 [mm]), It is possible spectroscopic measurement by separating the suspension to particle agglomeration area and the sparse liquid region of the particles.
The realization of compact size in-situ suspension tester is expected by combining the little finger size one-shot Fourier spectrometer.
In this study, we showed the feasibility of a possible switch the measurement object between floating particles and the liquid region.
