Abstract: The fingerprinting system includes a main body, an air movement source, an ignitor, and a hydrocarbon fuel source. The main body includes a handle. The air movement source includes a fan. The air movement source is coupled to the main body. The fingerprinting system is configured to burn the hydrocarbon fuel source to produce soot containing carbon. The air movement source is configured to direct the soot containing carbon toward a surface to be analyzed for fingerprints.

Abstract: Provided are methods, devices, and systems for identifying the concentration of delta-9-tetrahydrocannabinol (?-9 THC) in a given sample. The system allows for in situ formation of a chromophore eliminating the use of chloroform, wherein said chromophore absorbance spectra is measured using a spectroscopy method within a light wavelength range. The system allows for calculating the concentration of ?-9 THC using the linear relationship between the ?-9 THC level and the intensity of the color change in the present tester. Said linear relationship is obtained because the tester of the present disclosure allows the chromophore formation reaction go to completion.
