Download or read book Determination of Nitroaromatic Nitramine and Nitrate Ester Explosives in Water Using SPE and GC ECD Comparison with HPLC written by Marianne E. Walsh and published by . This book was released on 1998 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analytical method for the determination of nitroaromatic, nitramine, and nitrate ester explosives and Co-contaminants in water was developed based on SPE (solid-phase extraction) and GC-ECD (gas chromatograph-electron capture detector). Water samples are preconcentrated using either cartridge or membrane SPE followed by elution with acetonitrile. The acetonitrile extract is compatible with both liquid and gas chromatography, thereby allowing direct comparison of concentration estimates obtained by different methods of determination. Quantitative GC analyses were obtained by using deactivated direct-injection-port liners, short wide-bore capillary columns. and high linear carrier gas velocities. Recoveries from spiked samples were 90% or greater for each of the nitroaromatics and nitrate esters, and greater than 70% for nitramines and amino-nitrotoluenes. Estimates of analyte concentrations in well-water extracts from military sites in the United States and Canada analyzed by GC-ECD and the standard HPLC (high performance liquid chromatography) method showed good agreement for the analytes most frequently detected (HMX octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine, RDX hexahydro-1,3,5-trinitro-1,3,5-triazine, TNT 2,4,6-trinitrotoluene, and TNB 1,3,5-trinitrobenzene). The GC method provides lower method detection limits for most analytes than HPLC, but accurate calibration is more difficult. The ultraviolet (UV) detector used for the HPLC analysis has much greater linear range than the ECD used for GC analysis. In addition. the GC instrumentation requires more care than the LC. Specifically the injection port liner must be changed frequently to maintain accurate determination of the nitramines. Because the sample preparation technique yields extracts that are compatible with both GC and HPLC analysis, confirmation of analyte presence can be obtained based on different physical properties.

This book was released on 1965 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the chromatographic analyses on thin layer plates of several polynitroaromatic explosives from their corresponding decomposition residues after heat treatment at elevated temperatures. Explosives studied include treatment at elevated temperatures. The explosives included: sym-trinitrobenzene (TNB), picramide (PAM), diaminotrinitrobenzene (DATB), aminohexanitrobiphenyl (PIPAM), aminohexanitrobiphenyl (DIPAM), nonanitro-m-terphenyl (NONA), dodecanitroquaterphenyl (DODECA), and hexanitrostilbene (HNS). The results of the analyses are believed to be accurate to within + or - 5%. (Author).

This book was released on 1993 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: The article describes three brief experimental studies of the thin layer chromatographic (TLC) techniques used for forensic explosive investigations at Royal Armament Research and Development Establishment at Woolwich (RARDE Woolwich) in 1974. The first study demonstrated that 200 ng amounts of nitroglycerine (NG) and pentaerythritol tetranitrate (PETN) in TLC spots visualized using the sodium hydroxide/Griess system can be recovered and reanalyzed using a second TLC eluent. In the second study the characteristics of a titanium(III) chloride/4-dimethylaminobenzaldehyde visualization system for nitrotoluenes were investigated. In the third study it was shown that under certain conditions the rate of PETN spot color development after Griess reagent spray could be very slow in comparison with that of NG.

Book excerpt: Excerpt from Nitro-Explosives: A Practical Treatise Concerning the Properties, Manufacture, and Analysis of Nitrated Substances, Including the Fulminates, Smokeless Powders, and Celluloid In compiling the following treatise, my aim has been to give a brief but thoroughly practical account of the properties, manufacture, and methods of analysis of the various nitro-explosives now so largely used for mining and blasting purposes and as propulsive agents; and it is believed that the account given of the manufacture of nitro-glycerine and of the gelatine dynamites will be found more complete than in any similar work yet published in this country. For many of the facts and figures contained in the chapter on Smokeless Powders I am indebted to (amongst others) the late Mr J. D. Dougall and Messrs A. C. Ponsonby and H. M. Chapman, F.C.S.; and for details with regard to Roburite to Messrs H. A. Krohn and W. J. Orsman, F. I. C. To these gentlemen my cordial thanks are due.

Download or read book The Collection and Determination of Ethylene Glycol Dinitrate Nitroglycerine and Trinitrotoluene Explosive Vapors written by JE. Chrostowski and published by . This book was released on 1976 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: The identification of an explosive during a bomb scene investigation is a difficult and tedious task. The debris obtained from a bomb scene is usually first examined by microscopic means [1], with the hope of detecting some unconsumed explosive. Particles of suspected explosives are analyzed by using color spot tests or by solvent extraction procedures, with subsequent concentration and verification by thin-layer chromatography (TLC) or infrared spectroscopy (IR) This technique is time consuming if large quantities of debris are to be examined. One approach by which analysis time may be reduced is to scan samples from a bomb scene with a commercially available explosive detector such as a special purpose automated gas chromatograph vapor trace analyzer (VTA) [2]. Samples on which a positive response is obtained are retained for further analysis. A positive response on the VTA is an indication that an explosive vapor of commercial nitroglycerine dynamite has been detected. These selected samples should be further analyzed to confirm the presence of other related explosives [2]. Methods for analyzing explosive vapors by methods other than the VTA have also appeared in the literature [3,4].
