An apparatus and method in which one or more taggants that are intrinsically located or extrinsically placed in an article or product (11). The taggants are detected by X-ray fluorescence analysis (20, 21) to identify or verify the article of its point of manufacture. The taggants are manufactured as part of the article or the taggant is placed into a coating, label, or otherwise embedded within the article for the purpose of later verifying the presence or absence of these elements by X-ray fluorescence, thus determining the unique elemental composition of the taggant within the article.

L'invention concerne un appareil et un procédé consistant à placer un ou plusieurs traceurs instrinsèquement ou extrinsèquement dans un article ou un produit (11). On détecte ces traceurs grâce à une analyse par fluorescence X (20, 21), d'où l'identification ou la vérification de l'article ou de son lieu de fabrication. On peut intégrer ces traceurs à l'article en cours de fabrication ou les placer dans un revêtement, une étiquette ou tout autre élément ajouté à cet article, de façon à vérifier ultérieurement la présence ou l'absence desdits traceurs par fluorescence X. On détermine ainsi la composition élémentaire unique du traceur à l'intérieur de cet article.
