  • Patent number: 8404488
    Abstract: The invention is provided for detection of Heroin and Morphine in illicit drug samples, also for their differentiation. A liquid sample from a street sample is prepared and divided into two equal aliquots, one of them being reference sample, another being main sample. Both samples are treated with Hydrochloric acid and Sodium hydroxide, but those substances are added to the samples in the different sequence. After that the measurement of SFS of the reference sample is performed. Further the presence of specific spectral pattern of Morphine in the measured SFS of the reference, sample is detected and the value of SFS intensity at the specific spectral point is fixed (a reference value). After 15 minutes for acidification of the main sample, the analogous measurement and detection of the Morphine in the main sample are performed.

  • Patent number: 7995203
    Abstract: The invention is intended for illicit drug detection, preferably to Cocaine detection in street samples containing in addition to Cocaine also adulterants and/or diluents (also denominated as cutting agents) used for increasing the quantity of the product and/or for disguising the existence of Cocaine. The invention provides preparing of the liquid street sample, taking an aliquot of said sample, its analysis with help of SFS (Spectral Fluorescence Signatures) technology, fixing the result of analysis as a reference value, the subsequent acidification of the liquid sample, taking an aliquot of the acidified liquid sample and its analysis with help of SFS technology, fixing the result of analysis and comparing said result with the reference value. The result of comparison enables to differentiate between Cocaine Base and Cocaine hydrochloride in the street sample.
