Analysis of Explosives by GC-UV.
A mixture of explosives was analyzed by gas chromatography (GC) linked to ultraviolet (UV) spectrophotometry that enabled detection in the range of 178-330 nm. The gas-phase UV spectra of 2,4,6-trinitrotoluene (TNT), 2,4-dinitrotoluene (DNT), ethylene glycol dinitrate (EGDN), glycerine trinitrate (NG, nitroglycerine), triacetone triperoxide (TATP), and pentaerythritol tetranitrate (PETN) were s...
متن کاملForensic Analysis of Explosives by LC/MS.
Liquid chromatography/mass spectrometry (LC/MS), combining good separation characteristics with highly specific and sensitive detection, is the method of choice for forensic trace analysis of explosives. Principles of operation and instrumentation of several LC/MS interface/ionization modes are described. Among the various LC/MS interfaces and ionization modes, electrospray ionization (ESI)-LC/...
متن کاملTrace analysis of peroxide-based explosives.
The first method for quantitative trace analysis of peroxide-based explosives is described. A reversed-phase high-performance liquid chromatography method with post-column UV irradiation and fluorescence detection for the analysis of triacetone triperoxide (TATP) and hexamethylene triperoxide diamine (HMTD) has been developed. After separation, the analytes are degraded photochemically to hydro...
متن کاملSpectral Analysis for the Detection of Explosives with Differential Reflectometry
For explosive detection purposes, it is assumed that the person preparing or carrying the explosive will inadvertently contaminate him/herself or the exterior of the package. To detect such traces of explosive materials, we show the use of differential reflectometry (DR) as an alternative system to the existing techniques. With DR, explosives show characteristic behaviours at specific wavelengt...
متن کاملDestruction of peroxide explosives.
Chemicals containing multiple peroxide functionalities, such as triacetone triperoxide (TATP), diacetone diperoxide (DADP), or hexamethylene triperoxide diamine (HMTD), can be explosive. They are impractical and are not used by legitimate military groups because they are shock and heat sensitive compared to military explosives. They are attractive to terrorists because synthesis is straightforw...
