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.
