Premium Extended Expray Kit Has same tests as our best selling explosive detection kit Expray and in addition PDK kit.
Expray can detect the following groups of explosives:
- Group A: TNT, TNB, DNT, Picric Acid, Tri Nitro Napthalene, Lead Styphnate.
- Group B: Semtex, RDX, HMX, PETN, EGDN, Nitro Glycerin, Nitro Cellulose, Tetryl, Smokeless Powder.
- Group C: Ammonium Nitrate, Potassium Nitrate, Sodium Nitrate, Barium Nitrate, BlackPowder.
PDK kit can detect the following: chlorate and peroxide-based explosive compounds, including TATP (Triacetonetriperoxide).
Expray #1, #2, and #3 must always be used in sequence (starting with #1), using the same #530 test paper, until a color reaction occurs: then STOP. Expray #3 should be shaken well (5 seconds) after breaking ampoules (it has 2 ampoules).
 Remove or fold back the
protection layer from the test paper,
exposing the sticky collection
surface. Hold paper at bottom edge
(do not touch area to be used for test).
 Wipe the suspected area or touch
the suspected substance with the
collection paper. Put paper down

Check and compare results carefully
with the color chart.
List of Drugs
“E”: Expray-1 (# 1510) for Group A Expray-1 is used to search for GROUP A type explosives which include TNT, Tetryl, TNB, DNT, picric acid and its salts. To use, wipe suspected surface with special collector test paper. Spray with Expray-1. If a dark brown-violet color appears, this indicates the presence of TNT; An orange color indicates the presence of Tetryl and other GROUP A explosives.
“X”: Expray-2 (# 1520) for Group B Expray-2 is used to search for GROUP B type explosives which include Dynamite, Nitroglycerine, RDX, PETN, SEMTEX, Nitrocellulose and smokeless powder. If after spraying Expray-1 there is no color change, spray Expray-2. The almost immediate appearance of a pink color change indicates the presence of GROUP B explosives. Most plastic types of explosives belong to this group, including C-4 and Semtex.
“I”: Expray-3 (# 1530) for Nitrates Expray-3 is used to search for nitrate-based explosives which includes ANFO (ammonium nitrate-fuel oil), commercial and improvised explosives based on inorganic nitrates, black powder, flash powder, gun powder, potassium chlorate and nitrate, sulfur (powder), and ammonium nitrate (both fertilizer and aluminum). If there is still no reaction after using the Expray cans 1 and 2, but presence of explosives is still suspected, spray the same paper with Expray-3. A pink reaction indicates the presence of nitrates, which could be part of an improvised explosive.
