Experiment: Apply one microgram of TNT to a fingertip. Make successive fingerprints on ABS plastic. Analyze plastic using DART.

To demonstrate DART's ability to detect explosives in complex matrices, a sample of pond water was spiked with mixture of 3ppm each of various explosives. A 2mm diameter glass rod was dipped into the water and after the sample dried onto the tube it wa...

DART enables sampling directly from solid surfaces such as carpet fiber and tires.

Trace components in vapor can be easily detected after exposure of the surface of materials from crime scenes to the DART. In this example the presence of...

Negative Ion mass spectrum of Gunshot Residue (GSR) shows significant ions related to nitroglycerin and other materials.
