Alpha liquid scintillation was developed to obtain accurate analytical determinations of alpha-emitting nuclides where no other methods were sufficiently accurate. With the present emphasis on clean-up of radiation contamination, alpha liquid scintillation has become an important tool in the determination of low concentrations of alpha-emitting nuclides. This book is the first to address the subject of alpha liquid scintillation in its entirety. It also examines how alpha spectrometry by liquid scintillation can be done without interference from beta/gamma radiation. Scientists interested in the analysis of alpha-emitting nuclides for environmental monitoring, remediation clean-up, accountability, and research will find this to be a valuable book.

Highly accurate chemical speciation is of great importance in environmental, clinical, and food sciences, as well as in archaeometry. Trace analysis via atomic spectrometry, mass spectroscopy, gas chromatography, electron microprobing, or X-ray absorption spectroscopy provides detailed information on surface and sub-surface domain of samples. The book comprehensively presents modern techniques, timely application, and data modeling.

Food traceability is a growing consumer concern worldwide. Traceability is undertaken primarily at the administrative level, where the use of advanced analytical tools is not available. Nevertheless, the determination of geographical origin is a requirement of the traceability system for the import and export of foodstuffs (EU regulation 178/2002). The topics covered in this book include the history of traceability; legislations and rules; the actual traceability techniques and the potential analytical techniques for food traceability such as molecular methods (e.g. DGGE, SSCP), next generation sequencers (NGS), bio-captors, chromatographic techniques, isotopic analysis that are used for discrimination of organic food, fish, oils. The chromatographic techniques help in the use of volatile compounds analysis. The isotope analysis helps in distinguishing between chicken meat and vegetable oils. Ambient mass spectrometry is used for studying mycotoxines and alkaloids in foodstuffs and their management, food and feed authentication in olive and other plant oils, and wine. Vibrational methods (e.g. NMR and NIRS) are used to trace food by global spectrum. The book reviews the current and future techniques including metabolomic techniques.

It includes examples and problems representing a cross section of organic chemistry to help readers integrate the principles presented.

Quality and reliability are central to success in every discipline, but perhaps nowhere are they more important or more interconnected than in the practice of analytical chemistry. Here, although reliable analytical information implies quality, not all "quality" information proves reliable. Quality and Reliability in Analytical Chemistry examines the various factors affecting these parameters in each step of the analytical process: The Sample: Investigate the reliability of the sample, including its history and homogeneity. The Method: See the connection between reliability and the selection of analytical methods for environmental, food, and clinical analyses. The Instruments: Examine the relationship between reliability and your instrumentation. Data Processing: Consider the importance of chemometrics in the reliability of data processing. Automation: Explore automation of the analytic process through discussion of its parameters - rapidity, reproducibility, flexibility, and reliability. Standards and Standardization: Understand how quality and reliability cannot be assured without using standards for measurement and how only reliable methods can be standardized. The goal of the analytic process is to obtain high quality information with high reliability. Quality and Reliability in Analytical Chemistry helps you meet that goal and thereby satisfy your quality assurance and quality control requirements.

Of the 90 chemical elements that occur in nature, only a dozen are found in easily measurable amounts in the human body. The rest are trace elements, present at such low concentrations that most of them were, until quite recently, beyond the reach of detection. The Crumbs of Creation reviews the absorbing story of trace elements in medicine, history, industry, crime, and folklore, showing how the study of their properties can help us survive through a better understanding and control of our environment. Written in an easy-to-read, entertaining style, the book consists of interrelated anecdotes grouped together in relevant chapters. Although readers will derive much entertainment from this book, there is an underlying seriousness to the topics.

There are many different analytical techniques used to identify and quantify a wide range of substances in complex matrices such as the atmosphere, factory air, water, plants, soils, foods and industrial and pharmaceutical products. It is therefore of critical importance for researchers in many fields in both industry and academia to be familiar with the most suitable methods for their own applications, and to know how to get the best results when using these methods. Analytical Chemistry of Complex Matrices systematically discusses the key elements of the analytical process, from definition of the problem through sampling and separation, to calculation of the analytical result and ultimately the solution to the problem. Subsequent chapters are arranged by analyte type (such as inorganic, organometallic and organic analytes) rather than by analytical technique, and present selected analytical problems involving a broad range of analytes and matrices. A wide range of techniques is covered, from classical techniques such as gravimetry and titrimetry to state-of-the-art instrumental techniques such as high performance liquid chromatography and inductively coupled plasma mass spectrometry. Worked calculations are included throughout and careful attention is paid to the underlying chemistry of each analytical method. Analytical Chemistry of Complex Matrices will be of great interest to all research students and practising scientists whose work involves qualitative and quantitative analyses of complex matrices. Its highly practical approach, combined with the broad range of analytes, matrices and techniques considered, will make it an invaluable source of information to all such workers in both industry and academia.

Jason Woolford's thesis describes for the first time, a double [3+2] photocycloaddition of alkenes onto aromatic rings. Modern synthetic chemistry relies on the ability of researchers to uncover new and more efficient ways of creating highly complex structures. This work describes a novel, environmentally friendly photochemical step that converts in one pot, trivial starting materials into otherwise difficult to construct fenstrane frameworks. The rigid cores of these frameworks have significant potential in drug design. Moreover, the novelty of this work overtakes many other methods for the creation of chiral centres. No less than seven chiral centres are created in the photochemical step together with the formation of four carbon-carbon bonds and multifused rings. Jason's innovative work has been the subject of several publications in peer-reviewed journals.
