Abstract: An enhanced photoemission spectroscopy (EPS) system uses at least three photoelectric detection processes to identify a substance or substances in a target. The target can be in a container, and the EPS system accounts for this in the identification process. The photoelectric detection processes include Raman scattering, fluorescence and spectral reflection. The EPS system uses all three processes to generate spectral data that is then combined to derive a target signature. The target signature is then compared to stored signature data to determine the substance or substances in the target.

Abstract: A handheld or portable detection system with a high degree of specificity and accuracy, capable of use at small and substantial standoff distances (e.g., greater than 12 inches) is utilized to identify specific substances and mixtures thereof in order to provide information to officials for identification purposes and assists in determinations related to the legality, hazardous nature and/or disposition decision of such substance(s). The system uses a synchronous detector and visible light filter to enhance detection capabilities.

Abstract: The invention provides a cuvette apparatus having two cavities that are in fluid communication with each other. The first cavity is larger than the second cavity an receives a fluid to be studied. The second cavity holds the fluid for analysis and is bounded by at least two thin walled windows that allow superior transmission of UV waves.

Abstract: The invention provides a system and methods for centralized collection and verification of controlled substance/pharmaceutical waste. The invention provides a system and methods that replace the witness's co-signature with a process of centralized pharmacy controlled substance validation. In this process, the administering health care practitioner or nurse will give the medication to the patient and return the wasted portion of the dose to a secured storage area for a centralized pharmacy to pickup. The collected doses are then validated at the centralized pharmacy. Validation can include determining the composition, concentration, amount and type of drug.

Abstract: A system and method for detecting a substance using x-ray fluorescence is disclosed. The detected substances may be explosives or controlled substances that have a specific chemical fluorescent signature. An energy source transmits an x-ray beam at a target. The target may be in a container or under a surface. The beam interacts with the target to produce fluorescent energy. An x-ray detector is at an angle relative to the energy source and gathers the fluorescent energy. The angle differs according to the physical configuration of the system. A portable embodiment will have a different angle than a stationary embodiment. A cooling mechanism cools the x-ray detector. The fluorescent energy is analyzed and processed by a multichannel analyzer and a computer. The computer determines whether the fluorescent energy from the target matches known fluorescent energies of specific substances. If the substance is detected, appropriate indications are made to prevent damage or acceptance of the substance.
