  • Method for studying liquid and device for carrying out said method
    Patent number: 6874357
    Abstract: The present invention relates to physical chemistry and can be used for a quality test of liquids, in particular, multi-component liquid products, to ascertain the conformity of various process liquids, pharmaceutical preparations, foodstuffs, biological liquids to standard in pharmacology, food processing and chemical industries, and in medical diagnostics. The method of invention enables determining of the mechanical impedance within a drop (1) of test liquid having a specified volume, in the preferred embodiment, 5 mcl, placed on the surface of a piezoelectric resonator (3) of ultrasound frequencies, which provides for excitation of shear modes within drop (1) while it is drying up. The obtained time dependence of the mechanical impedance of drop (1) is used as the information parameter.
