Abstract
Disclosed herein is a method of identifying a unidentified substance, comprising directing light from a light emitting source directly upon a stationary unidentified substance; collecting fluorescence from the unidentified substance in a detector; wherein the detector comprises a lock-in detection system; analyzing the fluorescence; and identifying the unidentified substance. Disclosed herein is a detection system comprising a light emitting source; a circuit board; wherein the trigger is operative to trigger a pulse of electrons from the circuit board to the light emitting source; a detector; and a central processing unit, wherein fluorescence generated from an unknown unidentified substance that is illuminated by light from the light emitting source is collected in the detector and analyzed in the central processing unit.
