摘要： A portable substance identification system and method are configured to identify at least one detection target faster and with greater accuracy than is possible using prior substance identification systems and/or prior substance identification techniques. An embodiment of the portable substance identification system includes a portable substance identification device containing a Raman spectrometer, and a collection stem that includes a dry collector. One or more reservoirs for a liquid medium and /or a reagent can be formed in a cartridge that is configured to couple with a portable substance identification device. The cartridge has a chamber in which the reagent, liquid medium, and a detection target picked up by the dry collector are mixed. A magnet, positioned at a slant angle, can be used to form at least one pellet of aggregated magnetic particles within a pellet forming area of the chamber. The pellet is formed to maximize its surface area.

摘要： Methods, systems and computer program products for identifying components of an unknown mixture using spectral analysis techniques. The method includes comparing the spectrum of the unknown mixture with the spectra of library compounds to obtain candidate mixture combinations. A model is generated for each of the candidate mixture combinations based on a modeling metric. A residual spectrum is computed corresponding to each of the candidate mixture combinations by removing the spectrum of each of the compounds of the candidate mixture combination from the spectrum of the unknown mixture. One or more potential compounds are identified by comparing the residual spectrum with the spectrum of library compounds. The potential compounds are added to the candidate mixture combinations to generate an updated list of the candidate mixture combinations. The search algorithm repeats the steps described above on the updated candidate mixture combinations, until a first termination condition is satisfied.

摘要： An apparatus for generating a Raman signal of a test sample is disclosed. The apparatus includes a first optical path, a second optical path, a first station, and a second station. The first optical path is adapted for coupling with a radiation source that produces a test beam at the first optical path. The first station is responsive to the test beam and is adapted to house a test standard. The second station is responsive to the test beam and is adapted to house the test sample. In response to the test beam, Raman radiation from the test standard and the test sample are combined and directed to the second optical path, which is adapted for coupling with a spectrometer and a detector for producing a Raman spectrum of the test sample.
