General Description
Expray, DropEx, and Expens utilize the same reagents in different delivery packages (aerosol, bottle, ampoule). Basic kits detect (bulk or trace) substances for nitro aromatics, nitro-esters and Nitramines, and nitrates. Users are military, EOD, perimeter/ infrastructure/checkpoint security including K-9, environmental analysis, labs.
Technical Description
Technology uses wet chemistry reagents that elicit color reactions when applied to targeted substances from chemical interactions.
