Abstract: A method and apparatus for identifying and differentiating multi-component mixtures and identifying contamination thereof using direct comparison of characteristics of the analyte and characteristics of a standard sample of a known compound. These characteristics were obtained using methods and apparatus of spectrum analysis ensuring the possibility of receiving characteristic optical shapes (multi-dimensional signatures) of samples under comparison, which signatures represent a total set of spectral distributions of intensity values for light subjected to interaction with a sample, and the process of correlation of relative intensity values of light subjected to interaction with a sample at assigned wavelengths.

Abstract: Process and device for card generation and labeling for extracted or manufactured consumer products, which enables nondestructive contactless product inspection and/or authentication, including card generation and inspection of packaged products without damage to containers, identification of trade specimens of a product made by a specific manufacturer at every step of its distribution, and detection of counterfeit products and/or detection of product taint or contamination. The process uses the apparatus and methods of spectral analysis to form characteristic multidimensional optical images (signatures), fingerprints, and/or data profiles. Such images are presented as a digital, magnetic, graphic, holographic or other code that can be read by special devices and/or by visual comparison.
