Paper Abstract

We propose a method for studying multi-component liquids based on recording of the dynamics of the acoustic-mechanical impedance (AMI) of a drop that dries up on the surface of a quartz resonator oscillating with ultrasound frequency. The magnitude of the AMI is an integral characteristic of the physical properties of the drop including its viscosity, composition, surface tension, moistening, and inner structure. Using liquids of different types as the example, it is shown that each liquid possesses its individual 'portrait', determined by the character of the phase transitions. In the authers’ opinion, this method can be used for the screening identification of liquids (determining the degree of consistency with the standards) in solving a number of scientific and practical problems, as well as in biology, chemistry, food and drug examination and medicine. Unique scopes of this method in medical diagnostics, vine, food and drug identification and determination of inner structure of solutions are demonstrated.
