| Popis: | An original method and a device for obtaining fingerprints of liquids are proposed. According to this method, a fingerprint is a dynamic parameter - an oscillogram of the electrical impedance of a quartz sensor on which a drop of the studied liquid dries. The design of the device and the principle of its operation are described. The method can be used for a quick and inexpensive assessment of the degree of compliance of a liquid with the standard. Moreover, the degree of the difference between liquids of different compositions is expressed quantitatively. The device is a compact console for a laptop. The method is implemented in the range of room temperatures and humidity. The work of the E-taster is demonstrated by comparing the fingerprints of spirits, wines of different types and brands and solutions of milk powder of different concentrations.
