Available in PDF, EPUB and Kindle. Book excerpt: Characterization of the vapor from explosives is required for development of mine and explosives detection systems based upon trace gas analysis. This study was undertaken to evaluate the suitability of gas chromatographic electron capture techniques for investigating the composition of military grade TNT vapor, and to determine the mass spectra of the components in the vapor phase. Using a gas chromatographic method, the DNT and TNT isomeric impurities in vapor in equilibrium with typical military grade TNT were established. The 2, 4 DNT content of the vapor was almost as high as that of 2, 4, 6 TNT, the major component of the solid TNT. Mass spectra of all possible DNT and TNT isomers with the exception of 3, 4, 5 TNT were obtained as a function of ionization voltage. Mass spectra were also taken of several military grade TNT samples. Mass peaks common to both 2, 4 DNT and 2, 4, 6 TNT at m/e = 63 and 89 may be diagnostic for TNT using fragment ion type detection systems in that these peaks are not found in the mass spectra of compounds present in the atmosphere.
Download or read book Exploratory Analysis of Vapor Impurities from TNT RDX and Composition B written by and published by . This book was released on 1973 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vapors collected from TNT, RDX and composition B explosives maintained at 25C and 70C were analyzed using a gas chromatographic/mass spectrometric technique to identify the most prominent vapor components. A gas chromatograph equipped with electron capture and flame ionization detectors also was used to screen vapors for components present at concentrations below the sensitivity of the GC/MS. Cyclohexanone which could have significance in development of an explosive or mine detector was identified in vapors from RDX and composition B. Water vapor, carbon dioxide, probably nitrous oxide and a number of unidentified compounds were evolved from all samples. It may be possible to identify these unknown compounds present at trace levels, but extreme analytical care and precaution to avoid contamination would be required. In this regard, differentiation between compounds which are incorporated into the explosive matrix during manufacturing and those which are adsorbed from air by the explosive at a later time is also required.

Book excerpt: The vapor evolving from several types of intact military mines was analyzed using gas chromatography and gas chromatography/mass spectroscopy. Cyclohexanone was positively identified in the vapor from M15 (metallic) and M19 (nonmetallic) antitank mines. This compound originates from composition B, the explosive used in these mines. Acetone, toluene and an unknown organo-silicon compound were identified and are attributable to the nonmetallic mine casings. Although positive mass spectral identification is lacking, chromatographic data obtained using an electron capture detector indicated that 2, 4, 6 trinitrotoluene was detected in the vapor from the M16 (metallic) antipersonnel mines which are loaded with TNT.

Download or read book The Analysis of Explosives written by Jehuda Yinon and published by Elsevier. This book was released on 2013-10-22 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Analysis of Explosives surveys the principles of the various analytical methods, describes how these methods are used for the analysis of explosives, and reviews the major analytical work carried out in this field. Organized into 15 chapters, this book begins with the classification of explosives. Subsequent chapters discuss the different methods for the analysis of explosives. The detection and identification of explosive residues and hidden explosives are also explained. This monograph will be useful as a reference book for chemists in analytical and forensic laboratories, as well as a textbook for graduate students in analytical chemistry and forensic sciences.

Available in PDF, EPUB and Kindle. Book excerpt: Atmospheric samples were taken at the soil surface above field- emplaced M-15 and M-19 antitank mines and military explosive Composition-B. These samples were analyzed to determine if trace chemicals generated by the explosive material are detectable. Cyclohexanone was positively identified and is attributable to the explosive. Calculations were made, based on the amount of cyclohexanone found, to approximate its flux rate through the surface.
