Explosives Detection Kits

Complementing our Drug Trace Detection products, DTect now offers explosives detection kits. As with our drug detection suite, these explosives detection products use the latest technology to provide explosives detection that is both convenient and highly accurate.



Expray™ is a unique, aerosol-based field test kit for the detection and identification of Group A explosives (e.g. TNT, TNB, etc.), Group B explosives (e.g. Semtex H, RDX, C4, etc.) and compounds containing inorganic nitrates that are used in improvised explosives (e.g. ANFO).

Expray™ is used as a pre-blast, analytical tool, and post-blast investigative tool, to screen against potential terrorist elements, and as a technical evaluation test in soil remediation on hazardous material “clean-up” sites. When used as a post-blast investigative tool, the product is proven to speed up crucial investigations.



DropEx is a non-aerosol explosive detection kit based on the same chemistry as EXPRAY™. However, the DropEx Plus kit offers additional detection capabilities. DropEx Plus detects the widest possible range of explosive types, due to its ability to detect the Chlorate and Peroxide-based explosives often used for improvised explosives.

Peroxide-based explosives are powerful explosive substances that can be prepared from several over the counter materials. This well–known explosive type is currently in use by terrorist groups. This explosive material is usually known by its abbreviation TATP (Tri Acetone Tri Peroxide).

This system is based on the same reagents in Expray™, but in dropper bottles, for ease of use during field and laboratory investigation.


Testing Process

The testing process is fast and efficient, requiring no glass ampoules, spatulas or waiting period; the results appear in seconds, no additional tools or equipment required. The identification/detection process requires no special training and testing can be performed on the spot.
