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.
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
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 spectrometry The 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 provides a line of communication between academia and end users/practitioners to advance forensic science and boost its contribution to criminal investigations and court cases. By covering the state of the art of promising technologies for the analysis of trace evidence using a controlled vocabulary, this book targets the forensics community as well as, crucially, informing the end users on novel and potential forensic opportunities for the fight against crime. By reporting end users commentaries at the end of each chapter, the relevant academic community is provided with clear indications on where to direct further technological developments in order to meet the law requirements for operational deployment, as well as the specific needs of the end users. Promising chemistry based technologies and analytical techniques as well as techniques that have already shown to various degrees an operational character are covered. The majority of the techniques covered have imaging capabilities, that is the ability to visualize the distribution of the target molecules within the trace evidence recovered. This feature enhances intelligibility of the information making it also accessible to a lay audience such as that typically found with a court jury. Trace evidence discussed in this book include fingermarks, bodily fluids, hair, gunshot residues, soil, ink and questioned documents thus covering a wide range of possible evidence recovered at crime scenes.

An essential book for the practicing mass spectroscopist A genuine 'how-to' text for the practitioner focusing on quantification rather than instrumental design and techniques Up-to-date structured text describing methods, experimental strategy, capabilities and limitations, with data analysis and interpretation Brings together material widely dispersed in the pertinent literature into one unique source Internationally recognized group of authors
Clear, comprehensive, and state of the art, the groundbreaking book on the emerging technology of direct analysis in real time mass spectrometry Written by a noted expert in the field, Direct Analysis in Real Time Mass Spectrometry offers a review of the background and the most recent developments in DART-MS. Invented in 2005, DART-MS offers a wide range of applications for solving numerous analytical problems in various environments, including food science, forensics, and clinical analysis. The text presents an introduction to the history of the technology and includes information on the theoretical background, for exampleon the ionization mechanism. Chapters on sampling and coupling to different types of mass spectrometers are followed by a comprehensive discussion of a broad range of applications. Unlike most other ionization methods, DART does not require laborious sample preparation, as ionization takes place directly on the sample surface. This makes the technique especially attractive for applications in forensics and food science. Comprehensive in scope, this vital text: -Sets the standard on an important and emerging ionization technique -Thoroughly discusses all the relevant aspects from instrumentation to applications -Helps in solving numerous analytical problems in various applications, for example food science, forensics, environmental and clinical analysis -Covers mechanisms, coupling to mass spectrometers, and includes information on challenges and disadvantages of the technique Academics, analytical chemists, pharmaceutical chemists, clinical chemists, forensic scientists, and others will find this illuminating text a must-have resource for understanding the most recent developments in the field.
