Definitions
- the present invention uses x-ray fluorescence analysis to detect at least one taggant which is intrinsically or extrinsically present in the material of a product or article.
- XRF x-ray fluorescence
- the x-rays emitted from each element bear a specific and unique spectral signature, allowing one to determine whether that specific taggant is present in the product or article.
- Such a code could be based on the number and types of taggants present or absent, an abundance ratio (i.e., concentrations) of the same or different taggants, the location of the taggants within the material (i.e., a barcode made of a series of taggants with a space, where the space could be part of the code), the presence of multiple types or forms of a single taggant, or a combination thereof.
- the at least one taggant can be incorporated in the target material using any suitable technique.
- Many existing tagging techniques involve the use of microparticles containing the elements, or compounds or compositions of the elements, comprising the at least one taggant.
- particles can be manufactured wherein smaller particles, or compounds or compositions of the elements, containing the taggant.
- Such particles could be made of: magnetic or fluorescent materials to facilitate collection; refractory materials to enhance particle survival in an explosion; or chemically inert materials to enhance particle survival in a chemical reaction.
- Such particles could be made of non-durable, soluble, or reactive materials to enhance taggant dispersal in a fluid, aerosol, or powder system.
- the at least one taggant can be incorporated as an element or compound in solution with the liquid.
- the at least one taggant can be incorporated in elemental or compound form either in solution or suspension in the target material.
- the at least one taggant could also be dissolved or suspended in a solvent used in making the target material so that when that solvent evaporates, the residue left behind would contain the at least one taggant.
- the analyzer means can be a multi-channel analyzer for measurements of the detected radiation in the characteristic band and any other bands necessary to compute the value of the characteristic radiation as distinct from the scattered or background radiation. See, for example, U.S. Patent Nos. 4,862,143, 4,045,676, and 6,005,915, the disclosures of which are inco ⁇ orated herein by reference.
- Analyzer means which includes a computerized system 27, is coupled to, receives, and processes the output signals produced by detector 21.
- the energy range of interest which includes the energy levels of the secondary x-ray photons 44 emitted by the taggant(s), is divided into several energy subranges.
- Computerized system 27 maintains counts of the number of X-ray photons detected within each subrange using specific software programs, such as those to analyze the detection and x-ray interaction and to analyze backscatter data. After the desired exposure time, computerized system 27 with display menus stops receiving and processing output signals and produces a graph of the counts associated with each subrange.
- FIG. 6 illustrates a prefe ⁇ ed apparatus and detection method according to the present invention.
- detection apparatus 25 is capable of detecting at least one taggant present in target material 10, such as a sample of ca ⁇ et.
- Detection apparatus 25 is a portable device which can be small enough to be hand-held.
- Detection apparatus 25 contains all the components discussed above (i.e., source, detector, analyzer means, and calibration means) in a single housing, thus allowing the portability and smaller size.

Abstract
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.
