“…The extracts of post explosion debris, hand swabs, clothing or other samples containing explosive residues have been analyzed by various methods, often after some clean up. According to the type of the analyte, analytical methods are classified into two groups organic and inorganic [6][7][8][9][10][11][12].…”

One of the more challenging areas in the field of explosives is the analysis of explosive residues. The detection and identification of explosive traces on individuals, on clothing, in houses, in cars and on other related items are aimed to establish whether a contact with explosives has occurred. Such contact could indicate illegal possession or handling explosives or a possible involvement in shooting. Also, analysis of post explosion residues is one of the most technically difficult subjects in forensic science. The residual explosive has to be isolated from large amount of debris, often covering wide areas, and including large number of interfering items. In this work, in order to optimize a proper methodic way for post explosion analysis, artificial post explosion samples were created by mixing trace quantities of commonly used explosives with sand soil. Then sample extraction, filtration and concentration were carried out. Soil sample without any explosive traces was taken as a blank. The concentrated organic extract was then subjected to different available analytical chromatographic methods mainly HPLC, TLC, and spot test. Minimum detection limit of each technique was determined by gradually decreasing the amount of explosive residues in soil. Real explosions were carried out in the field, and post explosion samples were collected and investigated till complete identification of the exploded charge [1][2][3][4][5].

High-performance thin layer chromatography (HPTLC) has been used for the separation and quantification of 2,4,6-trinitrotoluene (TNT) and pentaerythritol tetranitrate (PETN). The compounds were separated on silica gel 60 F 254 with a double development system of trichloroethylene -acetone 4 : 1 and petroleum ether -acetone 5.7 : 1. For obtaining chromatograms of these materials, UV detection was performed at 215 and 250 nm for PETN and TNT, respectively. The linear dynamic range was 0.835 -83.50 mg per spot for PETN and 0.045 -1.44 mg per spot for TNT.

“…Chromatography permits the separation, detection and identification of both the explosive and non explosive components of energetic materials, allowing them to be identified and compared [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. During the investigation of an explosion incident, chromatography is an essential procedure used to separate trace amounts of unreacted explosives from a wide variety of sample matrices.…”

Chromatographic methods, mainly TLC, HPLC, and GC, are the most common methods in the routine analysis of explosives. In this study, these techniques were used to separate and identify some of the commonly used high explosives. Standard solutions of the investigated explosives and their mixture were prepared. TLC, HPLC, and GC-MS techniques were employed to establish methods for separation and identification of the explosives. Successful separation was achieved, the minimum detection limit was determined and specific methods were established for the analysis of the used explosives.
