Drop-Ex is an extension of the popular DROP-EX Kit.
It 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, or TATP (Tri Acetone Tri Peroxide).
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, and 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 A for Chlorates and Bromates – this type of explosives includes potassium chlorate and sodium chlorate. Drop-Ex # A is used for detection of chlorates and bromates and can be used by itself.
Drop-Ex B for Peroxide-based explosive compounds – includes TATP (Tri Acetone Tri Peroxide) and HMTD.
