ABSTRACT:
Methods and apparatus are disclosed for analyzing liquids utilizing cylindrical acoustic standing waves, generally in the ultrasonic region. The invention facilitates measurement of acoustic parameters of a fluid, such as sound velocity and attenuation, which themselves serve as indicators of solute concentrations and various ongoing chemical processes occurring. In preferred embodiments of the invention, cylindrical ultrasonic standing waves are generated in a liquid contained within a cylindrical housing by causing coherent oscillation of the entire cylinder, or a circumferential segment thereof, or multiple circumferential segments thereof. The invention is amenable to a variety of applications and implementations, most involving pairs of resonators, one containing a sample of the liquid under study, and the other containing a reference liquid.
