Abstract
Various embodiments of the present invention are directed towards a system and method to dispense an explosive compound onto a substrate. An example device includes a solvent having the explosive compound dissolved in the solvent to form a sample. A delivery mechanism dispenses the sample in a dispersed manner to sufficiently vaporize the solvent to prevent wicking while dispersing a residue of the explosive compound on the substrate to enable detection by explosive detection tools.
Claims2
A method to dispense an explosive compound onto a substrate, comprising:
- dissolving the explosive compound in a solvent to form a sample;
- disposing the sample in a canister;
- pressurizing the canister;
- coupling the canister to a delivery mechanism, that has a valve, so that the valve couples with the canister;
- actuating the delivery mechanism to open the valve;
- dispensing the sample from the delivery mechanism and toward the substrate in a dispersed manner so as to sufficiently vaporize the solvent, to prevent wicking, while dispersing a residue of the explosive compound on the substrate, to enable detection by explosive detection tools.
