Patent attributes
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 collector. One or more reservoirs for a liquid medium and/or at least one reagent can be formed in the collection stem. The cartridge can include a chamber in which the reagents, liquid medium, and at least one detection target picked up by the 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.
