Book SynopsisCovers new trace evidence techniques and expanding areas of analysis, along with key theory and applications Developed around the need for updated information in the disciplines of trace evidence the Handbook of Trace Evidence Analysis focuses on the increasing awareness and need for validation, modern methods for addressing and controlling contamination, the shift towards incorporating statistical analyses into the interpretation phase and cutting edge research into new forensic science methods and their application. Beginning with an overview of the topic and discussing the important role that information derived from trace materials can provide during investigations, the book then presents chapters on key techniques. The first being the critical nature of microscopy, and the methods employed for the recognition, collection, and preservation of trace evidence. Subsequent chapters review the core disciplines of trace evidence examination: paints and polymers, hairs, fibers and textiles and glass. Each chapter contains in-depth discussions on the origin of the materials involved, including any natural or synthetic processes involved in their production, the nuances involved in their detection, and the methods of analysis that are used to extract valuable information from samples. In addition, suggested workflows in method and testing selections, as well as addressing specific scientific challenges as well as the limitations of knowledge on the transfer, persistence and background abundance of trace materials are discussed. The book ends by examining the interpretation of trace evidence findings from a historical perspective and examining the methods that are currently being developed. Provides an in-depth introduction to the general area of trace evidence and discusses current and new techniquesConsolidates trace evidence and materials categories of testing into one reference seriesOffers a detailed focus on technical approaches and guidelines to trace evidenceIncludes analytical schemes/workflows and valuable guides for the interpretation of data and results The Handbook of Trace Evidence will appeal to forensic science academics, students, and practitioners in the trace evidence and materials science disciplines, as well as DNA analysts, toxicologists, forensic anthropologists, crime laboratory managers, criminal justice students and practitioners, and legal professionals. It would also be a valuable resource for every crime laboratory reference library.Table of ContentsList of Contributors xv Preface xvii 1 Trace Evidence Recognition, Collection, and Preservation 1Ted R.

Book SynopsisProficiency in volumetric analysis is a key skill for chemists in research and industry. This work seeks to ‘modernise’ approaches to volumetric analysis, by relating practical work to vocationally-relevant topics, whilst maintaining the rigor required for satisfactory performance in practical examinations. Written by someone who has experienced both teaching and working as a research chemist, this up to date textbook on practical volumetric analysis will provide the theoretical chemistry associated with volumetric analysis supported by a selection of practicals. There will also be suggestions for a number of investigations which could form the basis of project-based learning or coursework, particularly for those pursing vocational science courses. Section 1 will consist of three theory chapters, covering preliminary concepts (fundamentals of chemistry, essential quantitative chemistry and concepts of statistics). Section 2 will be divided into four chapters, based on the four main divisions of volumetric analysis (acid-base titrimetry, redox titrimetry, precipitation titrimetry and complexometric titrimetry). Each chapter in this section will start with a review of essential theory, with worked examples and illustrations where appropriate, and end with a selection of laboratory practicals. Each chapter will also contain a number of open-ended investigations, for use in project-based learning or coursework. Section 3 will address more advanced topics and be divided into four chapters (volumetric analysis in industry, further statistical concepts, mathematics of titrimetry and advanced titrimetry). Practical work and suggestions for further reading will be included where appropriate. Practical Volumetric Analysis is suitable for students taking modules in introductory chemistry and analytical chemistry on undergraduate degree courses as well as providing guidance to non-specialists teaching chemistry.Table of ContentsSECTION 1 PRELIMINARIES: Foundations of Chemistry; Essential Quantitative Chemistry; Statistical Concepts; SECTION 2 INTRODUCTORY VOLUMETRIC ANALYSIS: Basics of Volumetric Analysis; Acid-Base Titrimetry; Redox Titrimetry; Precipitation Titrimetry; Complexometric Titrimetry; SECTION 3 FURTHER TOPICS IN VOLUMETRIC ANALYSIS: Advanced Titrimetry; The Mathematics of Titrimetry; Volumetric Analysis in Industry; Further Statistical Concepts; Index

Book SynopsisInductively Coupled Plasma-Atomic Emission Spectroscopy (ICP-AES) has been widely adopted as a routine analytical technique for elemental analysis in both industry and academia. However, spectral interference can be a major problem, particularly with such line-rich elements as the rare earth elements. An Atlas of High Resolution Spectra of Rare Earth Elements, which comes complete with a CD of spectra in full colour, is a reference source suitable for all analytical spectroscopists. Using some previously unpublished high resolution spectra, this atlas enables users of ICP-AES to select the best lines of any single rare earth element matrix. Clear instructions for the use of the accompanying CD are provided, which allows all adjacent interferent spectral profiles to be displayed and superimposed. Up-to-date and informative, this unique book will be welcomed as a practical and indispensable reference guide by all those who use ICP-AES for the analysis of rare earth elements.Trade Review"... a valuable reference guide ..." * Journal of the American Chemical Society, Vol 122, No 18, p 4534 *"... a very useful book to have in the laboratory ..." * Talanta, 52, 2000, 955 *"... a helpful aid to any user of ICP with a special interest in the rare earth elements ..." * Journal of Analytical Atomic Spectrometry, 2000, 15 *"... a welcome addition to the current literature ... should occupy a space in any reference library." * Trends in Analytical Chemistry, Vol 20, No 1, 2001 *"... valuable and indispensable ..." * Fresenius Journal of Analytical Chemistry, 3/2000, M97-M98 *"...

Book SynopsisThe use of chemistry in archaeology can help archaeologists answer questions about the nature and origin of the many organic and inorganic finds recovered through excavation, providing valuable information about the social history of humankind. This textbook tackles the fundamental issues in chemical studies of archaeological materials. Examining the most widely used analytical techniques in archaeology, the third edition of this comprehensive textbook features a new chapter on proteomics, capturing significant developments in protein recognition for dating and characterisation. The textbook has been updated to encompass the latest developments in the field. The textbook explores several archaeological investigations in which chemistry has been employed in tracing the origins of or in studying artefacts, and includes chapters on obsidian, ceramics, glass, metals and resins. It is an essential companion to students in archaeological science and chemistry, as well as to archaeologists, and those involved in conserving human artefacts.Trade ReviewThis is a book which must be read by all serious students of archaeology and also by those like me who would like to know more about the past. -- Edward R.

Book SynopsisHow can a plant as beautiful as the foxglove be so deadly and yet for more than a century be used to treat heart disease? The same is true of other naturally occurring molecules as will be revealed in this current book by award-winning author and chemist, John Emsley. More Molecules of Murder follows on from his highly-acclaimed earlier book Molecules of Murder, and again it deals with 14 potential poisons; seven of which are man-made and seven of which are natural. It investigates the crimes committed with them, not from the point of view of the murderers, their victims, or the detectives, but from the poison used. In so doing it throws new light on how these crimes were carried out and ultimately how the perpetrators were uncovered and brought to justice. Each chapter starts by looking at the target molecule itself, its discovery, its chemistry, its often-surprising use in medicine, its effects on the human body, and its toxicology. The rest of the chapter is devoted to murders and attempted murders in which it has been used. But, be reassured that murder by poison is not the threat it once was, thanks to laws which restrict access to such materials and to the skills of analytical chemists in detecting their presence in incredibly tiny amounts.Trade ReviewA fascinating book, which I thoroughly recommend. -- Dr Simon Cotton, Honorary Senior Lecturer in Chemistry at the University of Birmingham * Chemistry & Industry, Issue 4, Reviews, More Posions *The book is aimed at the general reader and it fulfils this objective in an informative, clear and well-written style. The book will be of interest to those who enjoy crime novels, a number of which are mentioned in the text.

Book SynopsisCD and MCD spectroscopy can provide key information about the conformations and electronic states of chromophore containing molecules. However, the theory has remained too challenging and inaccessible for many organic chemists and biochemists and only a few researchers have carried out detailed quantitative analyses of their spectral data. This is not surprising as people who excel at spectroscopic theory usually lack the skills set required to design and synthesise the molecules that would be most appropriate for describing and explaining the theory of CD and MCD spectroscopy. Most of the books that have been written on the subject have, therefore, been based on very dense sets of mathematical equations. This timely book rectifies that situation by summarizing the relationship between the different types of spectra and by describing in detail the qualitative and quantitative methods which can readily be used to analyse CD and MCD spectral data. During the last decade the authors have successfully synthesized several molecules to illustrate key points related to the theory of CD and MCD spectroscopy, resulting in this definitive book providing key practical knowledge in a readily accessible style. It is aimed primarily at organic chemists and biochemists and provides the required reading for researchers active in the field. In the introduction, the book describes the types of information that can be derived from CD and MCD spectroscopy. After a detailed explanation of the theory of electronic absorption spectroscopy, it then provides practical in depth examples of the various analytical methods that can be carried out with CD and MCD spectral data. This makes the theory of these techniques much more accessible for researchers who do not specialise in physical chemistry.Trade Review"Their explanations of the CD techniques are complete enough to satisfy an expert spectroscopist while at the same time written in a way that can be understood by a non-expert organic chemist that is well versed in introductory physical chemistry." -- Babak Borhan * Angew.

Book SynopsisHigh-temperature liquid chromatography has attracted much interest in recent years but has not yet recognized its full potential in the chromatographic community. There is a widespread reluctance in industry to use temperature to speed up the separation process, influence the selectivity of a separation or implement novel detection techniques. However, the technology has now matured and could revolutionize chromatography as we see it today. Better equipment, such as heating systems able to generate faster heating rates, is becoming more readily available. Also, columns based on silica gel, which can withstand higher temperatures for an extended period, are now being introduced. Nevertheless, further technological and methodical efforts are needed to establish the method in a regulated environment like the pharmaceutical industry. This is the only text to cover all the practical aspects, as well as the underlying theoretical principles, of setting up an HPLC system for high temperature operation. It is not intended solely for academics but will also benefit the researcher interested in more practical considerations. The author is a recognized expert and has conducted several studies with partners from industry to validate the method. Many real examples from these studies have been included in the book. The aim is to support practitioners in the creation of their own protocols without the need to rely solely on trial and error. The book starts with a brief definition of high temperature liquid chromatography before going on to cover: system set up; the heating system; mobile phase considerations; suitable stationary phases; method development using temperature programming; analyte stability, and special hyphenation techniques using superheated water as a mobile phase. In each chapter, experimental data is used to illustrate the main statements and the advantages over conventional HPLC are evaluated. The book concludes with a critical outlook on further developments and applications underlining the necessary advances needed to make high temperature HPLC more robust.Trade ReviewHigh-temperature liquid chromatography has attracted much interest in recent years but has not yet recognized its full potential in the chromatographic community.

Book SynopsisPervaporation is a separation process in which the selective permeation of components of a liquid mixture is achieved by way of a chemical potential gradient through a non-porous membrane. In Pervaporation: Process, Materials and Applications, the fundamentals and applications of pervaporation are described as a promising technique for the recovery of flavor compounds from dilute aqueous solutions, separation of azeotropic mixtures and for the dehydration of organic solvents. This collection also describes history of pervaporation in an effort to outline the differences between this and other membrane separation technologies including dialysis, ultrafiltration, microfiltration, nanofiltration and reverse osmosis. The closing chapter focuses on the authors on-going development of high performance bio-based cellulosic membranes for ethyl tert-butyl ether purification by pervaporation. Cellulose acetate is extremely selective for ethanol removal from ethyl tert-butyl ether, however its flux is very low. Different strategies for improving its flux while maintaining a high selectivity are described and the main relationships between membrane structure, morphology and properties are illustrated.
