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 the group of compounds containing inorganic nitrates that are used in improvised explosives (e.g. ANFO).

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

The level of sensitivity (20 nanograms or less) 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 explosive detection tool for increasing the accuracy, efficiency and number of interdictions. For forensic and environmental laboratories, it has been 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 spray still contains active reagents, and for demonstrating how a positive reaction will appear) in a convenient plastic carry case. Expray® kits are available in both regular size (100 tests) and mini-size (50 tests).

Expray® provides a low "per test" cost and poses no risk to you or the environment.

Drop-Ex Plus is our latest Explosive Detection and Identification Kit. Drop-Ex is actually an extension of the popular DROP-EX Kit and detects the widest possible range of explosive types, due to its ability to detect the additional explosive categories for improvised explosives: Chlorate and Peroxide-based 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 (Triacetone Triperoxide).

This system is based on the same reagents in Expray® , but in a dropper bottles, for ease of use during field and laboratory investigation.
The detection range of the kits:

Drop-Ex # 1 for Group A (Nitroaromatics) - this type of explosives includes TNT, Tetryl, TNB, DNT, picric acid and its salts.

Drop-Ex # 2 for Group B (Nitrate esters and nitramines) - this type of explosives includes Dynamite, Nitroglycerine, RDX, C4, PETN, Semtex H, Nitrocellulose and smokeless powder. NOTE: Most plastic types of explosives belong to this group.

Drop-Ex # 3 for Inorganic nitrates - the nitrates based explosives include ANFO (ammonium nitrate-fuel oil), commercial and improvised explosives based on inorganic nitrates, black powder, flash powder, gun powder, potassium nitrate, and ammonium nitrate.

Drop-Ex U for Urea compounds.  

Drop-Ex A for Chlorates and Bromates – this type of explosives includes potassium chlorate and sodium chlorate.

Drop-Ex B for Peroxide-based explosive compounds – includes TATP (Triacetone Triperoxide) and HMTD

Drop-Ex # A is used for detection of chlorates and bromates and can be used by itself. Drop-Ex # B requires that Drop-Ex # A be used first. If you are not sure what type of explosive you are testing for, you will need two samples. The first sample can be tested using Drop-Ex 1, 2 and 3. The test for chlorates, bromides and the peroxide based explosives must be a separate test using Drop-Ex A and Drop-Ex B.
