Method detection limits are determined and compared for analysis of liquid injections of organic explosives and related compounds by gas chromatography-mass spectroscopy utilizing electron impact (EI), negative ion chemical ionization (NICI), and positive ion chemical ionization (PICI) detection methods. Detection limits were rigorously determined for a series of dinitrotoluenes, trinitrotoluene, two nitroester explosives, and one nitramine explosive. The detection limits are lower by NICI than by EI or PICI for all explosives examined, with the exception of RDX. The lowest detection limit for RDX was achieved in the PICI ionization mode. Judicious choice of the appropriate ionization mode can enhance selectivity and significantly lower detection limits. Major ions are reported for each analyte in EI, PICI, and NICI detection modes.

Forensic Investigation of Clandestine Laboratories, Second Edition is fully updated to address all aspects of the forensic investigation of clandestine laboratories. While, the first edition focused on the domestic clandestine manufacture of contraband substances, this edition expands the scope to more fully address the clandestine manufacture of explosives that have become a threat that is global in nature. In clandestine laboratory operations, equipment is often simple, household chemical products are utilized, and the education of the operators basic. In fact, most of the time these elements individually are perfectly legal to sell and possess. However, the combination of all these elements is what becomes the scene of illicit activity and a criminal operation. In response to the increase in use of homemade explosive mixtures by terrorists, both domestically and internationally, the section clandestine manufacture of explosives is greatly enhanced. Topics are presented in a manner which, while detailed, will not compromise the tactics, techniques, or procedures utilized by law enforcement and military personnel in their ability to combat the clandestine manufacture of contraband substances and the battle against domestic and international terrorism. Key features: • Examines tell-tale signs to look for in recognizing a clandestine lab • Outlines how to safely process the site of a clandestine lab • Details how to analyze collected evidence in the examination laboratory • Provides guidelines as to what to derive from the physical evidence • Offers specific tactics to effectively present the opinions associated with evidence that has been collected during the investigation in a written report, military style briefing or to a jury in a legal proceeding. Forensic Investigation of Clandestine Laboratories, Second Edition guides the reader through the process of recognizing these illegal manufacturing operations. Then it examines the methods as to how to compile the volume of associated evidence into a package that can be presented in a court of law, or to military commanders for decisive action. It is an invaluable resource, that will prove useful to chemistry lab technicians, forensic investigators, fire and first responder professionals, military personnel, police investigative agencies and narcotics units, and lawyer trying cases involving clandestine labs.

Gas chromatography-mass spectrometry (GC-MS) with supersonic molecular beams (SMB) (also named GC-MS with Cold EI) is based on GC and MS interface with a SMB and on the electron ionization (EI) of vibrationally cold analytes in the SMB (hence the name Cold EI) in a contact-free fly-through ion source. Cold EI improves all the central GC-MS performance aspects and brings a broad range of important benefits thereby leading the way to the future of GC-MS. Cold EI provides enhanced molecular ions combined with effective library-basedsample identification. Sample identification is further improved by the use of powerful TAMI software that is based on isotope abundance analysis and improved quadrupole mass accuracy for the provision of the sample elemental formula from its molecular ion group of isotopologues.

Mass spectrometry is one of the most versatile analytical techniques due to the vast range of analytes that it can detect and quantify and, as such, for its contribution to a significant number of life science fields. The legal and forensics community has certainly benefited from this technique, which has been able to provide reliable evidence in court cases. Liquid Chromatography/Gas Chromatography–Mass Spectrometry (LC/GC–MS) still have a dominant role in the provision of forensic intelligence. However, in the past decade new and exciting MS-based techniques have emerged and are or have evolved to be at an operational deployment maturity, enabling either fast, ambient, non-destructive, or portable screening (or encompass all of these features). In this book, developments of LC–MS and GC–MS based techniques are covered with respect to operational practice and new applications, accompanied by other MS-based techniques that are increasing forensic opportunities and that operate on a variety of evidence types. Whilst the underpinning working principles of each relevant mass spectrometry technique are summarised, each chapter primarily focuses on its implementation in criminal investigation and court cases. In the last chapters, this book additionally covers emerging MS technologies that are at the beginning of their operational implementation journey as well as niche applications outside the fields of traditional forensic science but with a clear potential to impact future investigations (forensics beyond the courtroom). This book provides an up-to-date reference for the mass spectrometry-based tools that are currently available both as established and as emerging methods within forensic practice. It will help casework commissioning managers and forensic providers worldwide to make more informed decisions as to the forensic strategy and workflow when examining exhibits. It is also recommended to postgraduates and early career investigators with reference to the contribution that these techniques and methods could make if applied to classic forensic science practice.
