The detection of hidden explosives has become an issue of utmost importance in recent years. While terrorism is not new to the international community, recent terrorist attacks have raised the issue of detection of explosives and have generated a great demand for rapid, sensitive and reliable methods for detecting hidden explosives. Counterterrorist Detection Techniques of Explosives covers recent advances in this area of research including vapor and trace detection techniques (chemiluminescence, mass spectrometry, ion mobility spectrometry, electrochemical methods and micromechanical sensors, such as microcantilevers) and bulk detection techniques (neutron techniques, nuclear quadrupole resonance, x-ray diffraction imaging, millimeter-wave imaging, terahertz imaging and laser techniques). This book will be of interest to any scientists involved in the design and application of security screening technologies including new sensors and detecting devices which will prevent the smuggling of bombs and explosives.* Covers latest advances in vapor and trace detection techniques and bulk detection techniques* Reviews both current techniques and those in advanced stages of development* Techniques that are described in detail, including its principles of operation, as well as its applications in the detection of explosives

An up-to-date handbook, with the latest advances including all the various methods and techniques for analyzing explosives. Explosive compounds and mixtures, residues--their recovery and clean-up procedures--chromatography, polarography, spectroscopy, environmental analysis and mass spectroscopy are among the topics covered.

Forensic and Environmental Detection of Explosives is the first comprehensive book on the detection of explosives. It combines the two main fields of application:* Forensic detection of explosives - the detection of hidden explosives in airfreight, luggage, vehicles, and on suspects.* Environmental detection of explosives - detecting on-site explosives in soil and water of contaminated areas and the detection of landmines.Dr Jehuda Yinon is a world renowned expert on the analysis of explosives and has served as consulting expert during the Oklahoma bombing trial, where his previous book Modern Methods and Applications in Analysis of Explosives was quoted by both the prosecution and defense experts. This new book complements the author's previous book on the analysis of explosives. It includes the following features:* Classifications of explosives* Explanations of the basic terms related to the detection of explosives* Vapor detection methods* Probing radiation methods* Tagging of explosives* Systems integration and performance testing* Detection of explosives in contaminated areas* Detection of landmines.This book is an ideal reference book for those working in forensic and law enforcement agencies concerned with the detection of hidden explosives, as well as for environmental scientists dealing with explosives decontamination. The book is also recommended as a text book for graduate students in analytical, environmental and forensic science.

This volume covers all aspects of explosives and explosive residue analysis and detection, fundamental studies, applications, developments and evaluation of instrumentation and methods, and improvements of established techniques. It is divided into five general sections: Analysis of explosive residues; Analytical methods; Energetic materials and mass spectrometry; Explosive detection; Vapour generation. This book should be of interest to all scientists working in forensic science, explosives - research, analytical chemistry and environmental sciences dealing with the analysis of explosives, aviation and general security, etc.

Recent developments in analytical instrumentation have had an enormous influence on forensic analysis. The mass spectrometer is now an integral part of every forensic laboratory, resulting in greater analytical accuracy, more reliable identification, and lower detection limits. As the instrumental method of choice among forensic analysts, the mass spectrometer continues to pave the way for innovative applications in forensic analysis.Exploring the latest developments in the field, Advances in Forensic Applications of Mass Spectrometry provides a comprehensive reference guide to forensic applications using modern mass spectrometry techniques. The book features methods developed from advanced instrumentation, drug detection and toxicological analysis, and methodology of applications of stable isotope ratios. The final chapters present approaches for identifying accelerants in fire debris and procedures for analyzing explosives in post-blast residues.Jehuda Yinon, Ph.D., is one of the top forensic chemists in the world. As the editor of this authoritative volume, he compiles the knowledge of leading experts to demonstrate the use of novel mass spectrometry techniques in a vast range of forensic applications.

The purpose of this important monograph is to provide the reader with a better understanding of the toxicity, channels of absorption, and metabolism of explosives by the body. This one-of-a-kind work also incorporates the symptoms and clinical manifestations of poisoning by these compounds. It discusses how the disposal of explosives and their degradation products from munition manufacturing plants affect our environment. This resource gives special attention to the methods of analysis of explosives and their metabolites in body fluids. It also features explosives and their degradation products in water and soil. This significant book provides an excellent review and reference for toxicologists, physicians, and environmental chemists interested in this field.

Forensic Applications of Mass Spectrometry combines the most current developments in applications of mass spectrometry techniques to forensic analyses. The techniques discussed include:capillary-GC/MS thermospray-LC/MS tandem mass spectrometry (MS/MS) pyrolysis-GC/MS isotope ratio mass spectrometryThe applications include: analysis of body fluids and hair for drugs of abuse drug testing in sports analysis of accelerants in fire debris detection of hidden explosives in luggage and mail identification of explosives in post-explosion debris examination of evidential materials (paints, fibers, synthetic polymers) authentication of regulated products (flavoring substances, fruit juices) protection of industrial products by isotopic signature

This book examines both the potential application of electronic nose technology, and the current state of development of chemical sensors for the detection of vapours from explosives, such as those used in landmines. The two fields have developed, somewhat in parallel, over the past decade and so one of the purposes of this workshop, on which the book is based, was to bring together scientists from the two fields in order to challenge the two communities and, mutually, stimulate both fields.It begins with a review of the basic principles of an electronic nose and explores possible ways in which the detection limit of conventional electronic nose technology can be reduced to the level required for the trace levels observed for many explosive materials. Next are reviews of the use of several different types of solid-state chemical sensors: polymer-based sensors, i.e. chemiluminescent, fluorescent and optical, to detect explosive materials; metal oxide semiconducting resistive sensors; and then electrochemical sensors. Next, different pattern recognition techniques are presented to enhance the performance of chemical sensors. Then biological systems are considered as a possible blue-print for chemical sensing. The biology can be employed either to understand the way insects locate odorant sources, or to understand the signal processing neural pathways. Next is a discussion of some of the new types of electronic noses; namely, a fast GC column with a SAW detector and a micromechanical sensor. Finally, the important issues of sampling technologies and the design of the microfluidic systems are considered. In particular, the use of pre-concentrators and solid phase micro extractors to boost the vapour concentration before it is introduced to the chemical sensor or electronic nose.
