METHOD FOR EXPRESS INSTRUMENTAL IDENTIFICATION OF THE AUTHENTICITY OF THE SMELL OF A PERSON AND CLOTHES

摘要

FIELD: analytical chemistry. ;SUBSTANCE: invention relates to the field of analytical chemistry. A method for express instrumental identification of the authenticity of the smell of a person and clothes is proposed. The method includes the measurement of the odor of the tissue of the examined clothing identical to the nature and in contact with the skin in the places of the greatest secretion of secretory fluids for at least 30 minutes of the carrier tissue and the clothes in contact with the person under study. The measurement is carried out using an electronic nose based on 4 piezo sensors modified by multilayer carbon nanotube phases, comparing pairwise the identical odors obtained for the carrier fabric and clothes in contact with a person, deciding on the identity of the odor of the fabrics if the differences of each parameter does not exceed 15%. ;EFFECT: invention provides a reduction in the time of analysis, an increase in productivity and objectivity. ;1 cl, 1 dwg
