Method for Marking and Identifying Manufactured Articles, Substances and Organisms, and Uses Thereof
The present invention comprises a method for marking and identifying manufactured articles, substances and organisms (referred to below as "products"), based on the addition to the product to be marked of a known mixture of two or more isotropic profiles of a single chemical element that are enriched in different stable isotopes. Identification thereof may be performed by measuring the ratio of molar fractions between those isotropic profiles present in the product using mass spectrometry. The present invention also relates to the use of the product marked by means of the above method for marking other products which are derived therefrom or which use it in their composition. The present invention is applicable to the concealed marking of manufactured articles, substances and organisms in the sectors of pharmaceuticals, explosives, jewellery, works of art, plants, foodstuffs and addictive drugs, among other things.
