Estimating the term…
The present invention relates to a method for associating information with an article, an isotopic labeling composition to label an article with information using at least two different isotopes of an element, and an article labeled with the labeling composition. In the labeling composition, the isotopes of the labeling composition have an abundance ratio that is detectably different from the natural abundance ratio thereof. By detecting the abundance ratio(s) of the isotopes in the labeling composition, via laser ablation/magnetic spectroscopy, an NQR spectrometer, an NMR spectrometer, an IR spectrometer, or a microwave spectrometer, information about the article can be determined. The invention may be used to identify, authenticate or determine the source or origin of an article or to provide detailed information about an article.
A method to associate information with an article comprising the steps of:
An isotopic labeling composition, which comprises at least two isotopes of an element at a predetermined abundance ratio between said at least two isotopes, wherein said predetermined abundance ratio is detectably different from the natural abundance ratio between said at least two isotopes.
An article of manufacture which comprises an isotope labeling composition, wherein said isotope labeling composition comprises at least two different isotopes of an element at a first predetermined abundance ratio that is detectably different from the natural abundance ratio between said at least two isotopes.
