  • Patent number: 9995681
    Abstract: Device and methods for detecting/quantifying a fluorescent taggant in a liquid sample. Generally, the liquid samples are fuels having low concentrations (measured in ppb) of a fluorescent taggant. The detection/quantification generates a predicted concentration of the fluorescent tagging compound using a process selected from the group of a multivariate process, a background subtraction process, or a combination of both. The invention addresses the detection of an adulteration of gasoline and diesel fuels.

  • Patent number: 9448171
    Abstract: At least two luminescent materials are intermingled within a security feature. The materials are selected from among a larger set of luminescent materials each having a different individual exponential decay characteristic (decay constant and initial amplitude response to the degree of excitation) for photo-luminescent emission from the respective material following excitation. The ratio of the decay constants for any two materials is greater than or equal to about 1.5. The selected materials are mixed in one of a plurality of predetermined ratios. The combined emissions from the intermingled materials appear, to an unsophisticated measuring device, to have a single exponential decay constant. Based on measurements for the decay of the combined emissions following excitation, estimates of the individual decay constants and associated initial emission amplitudes allow decoding of the particular combination of materials and/or their ratios to validate the security feature, authenticating the article.

  • Patent number: 9222043
    Abstract: Marking a petroleum product includes adding a covert dye selected from the group consisting of azadipyrromethene dyes, dipyrromethene dyes, and any combination thereof to the petroleum product and distributing the dye in the petroleum product. A petroleum product selected for analysis may be spectroscopically analyzed for the presence of an azadipyrromethene dye, a dipyrromethene dye, or a combination thereof. A concentration of at least one azadipyrromethene or dipyrromethene dye present in the portion of the petroleum product may be determined to identify the petroleum product as counterfeit, adulterated, or authentic based on the determined concentration of the azadipyrromethene or dipyrromethene dye.
