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 commonly used as a pre-blast, analytical tool, post-blast investigative tool, 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 field proven to speed up crucial investigations.

The level of sensitivity (20 nanograms) surpasses that of other currently available products. The testing process is fast and efficient. No glass ampoules, spatulas or waiting period required. 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".

For both law enforcement and investigative personnel, Expray is a proven tool for increasing the accuracy, efficiency and number of interdictions. For forensic and environmental laboratories, it has proven to reduce the number of samples submitted for testing, saving both time and money.

Expray is sold in a kit configuration, which provides all three aerosol sprays, collection papers, and an RDX-impregnated verification pad (verification pad is useful for ensuring that the spraycan still contains active reagents and for demonstrating how a positive reaction will appear) in a convenient plastic carry case.
