METHOD FOR CREATING INFORMATIVE-SEARCHING SYSTEM FOR DETERMINING SOURCE OF PRODUCTS ORIGIN AND METHOD FOR DETERMINING NATURE AND SOURCE OF MATERIALS ORIGIN, CONTAINING PLATINUM GROUP METALS, WITH USE OF AFOREMENTIONED INFORMATIVE-SEARCHING SYSTEM

摘要

FIELD: analytical chemistry.;SUBSTANCE: method for creating informative-searching system for determining nature and source of origin of natural and technological products, containing among others metals from platinum group, includes gathering and systematization of product analysis data, while a set of identification signs for analyzed objects included in informative-searching system is formed. Method for determining includes experimental determining of identification signs of object, comparing detected identification signs to the same in informative-searching system and determining nature and source of material origin.;EFFECT: increased trustworthiness, expressiveness and selectiveness.;2 cl, 3 dwg, 1 tbl
