This chemical analysis device is provided with: a plurality of ultrasonic elements; a waveform generator which generates an ultrasonic waveform; a determiner which determines the positions and the number of ultrasonic elements to be driven from among the plurality of ultrasonic elements; a variable matching circuit which, on the basis of the determination result, matches impedance between the waveform generator and each of the ultrasonic elements to be driven; and a switch which selects the ultrasonic elements to be driven from among the plurality of the ultrasonic elements.

External sonication, which is a technique by which ultrasonic energy is applied externally to a cartridge containing the sample, is contemplated herein. External sonication can be performed by a sonicator external to a sample contained within a cartridge. The cartridge can include sonication particles to enhance sonication or cavitation within the sample. A sonication algorithm can also be used to increase sonication efficiency.

The present disclosure relates to a method of creating a propellant mixture. The method includes forming an explosive composition mixture, placing the explosive composition mixture into a mixing vessel assembly, and operating an acoustic mixing system at an operating frequency such that the acoustic mixing system causes a vertical displacement of the mixing vessel. The explosive composition mixture has an explosive material, and one or more additives. The mixing vessel assembly has a closed mixing zone having a maximum vertical height. The acoustic mixing system is operated in a manner such that the operating frequency is substantially similar to the resonant frequency and a ratio of the maximum vertical height of the closed mixing zone to the vertical displacement of the mixing vessel assembly is 2.0 or less.

An ultrasonic mixing apparatus and method is provided for cavitation and processing an aqueous first fluid with an oil-based second fluid, e.g., cannabinoids in a sonication or cavitation zone. The apparatus can be used for preparation of nano-particle emulsions of oil-based botanical extracts in aqueous fluids for therapeutic consumption. The apparatus is effective in producing increased bioavailability of the botanical extract due to the small particle size created through cavitation.

Provided is a bubble volume control method and apparatus, and more particularly, to a bubble volume control method and apparatus for controlling the volume of a bubble by increasing or decreasing the volume of the bubble by emitting an ultrasonic wave having a resonance frequency corresponding to the size of the bubble located at the bottom of a container containing a liquid, such as water with bubbles composed of air, vapor, etc., toward the bubble by using an ultrasonic generator above the container, and maximizing a function of adjusting the volume of a bubble through a resonance effect by adjusting a liquid surface height of a liquid with the bubble according to a wavelength of an emitted ultrasonic wave.
