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.

The working title of the book was The Detection of Analytes by the Resin Spot Tests Method. Firstly, we decided to sort out all published qualitative methods systematically against analytes. We were not discouraged by the obstacles, such as the study of a great number of papers published in Japanese, the difficulty in locating (especially older) publications, or the time required. Still, having in mind not to burden unnecessarily the volume of the book, we dismissed the idea of systematically listing all the procedures in detail. Nevertheless, a relatively large number of them found a place in the book, and perhaps this will contribute to the stirring of spontaneous interest in this technique in the ranks of applied chemists and others who a priori shun the technique.

The principle objective of this handbook is to provide a readily accessible source of information on the major fields of spectroscopy. Specifically, these fields are NMR, IR, Raman, UV (absorption and fluorescence), ESCA, X-Ray (absorption diffraction fluorescence), mass spectrometry, atomic absorption, flame photometry, emission spectrography, and flame spectroscopy. It will be of particular use to analytical, organic, inorganic chemists or spectroscopists wishing to identify materials or compounds. The book will indicate to them which techniques may provide useful information and what kind of information will and will not be provided. In short, it will be a companion to those spectroscopists who have need to broaden their horizons into the major fields discussed.

Mass spectrometry has played an integral part in the study of organic molecular structures for more than 50 years, offering significant information from small amounts of sample. The mass spectrum produced by electron impact ionization presents a pattern of peaks that can often give definitive structural information about an unknown compound. Introductory Mass Spectrometry, Second Edition guides readers in the understanding and recognition of those patterns, discussing mass spectra in terms that are familiar to chemists. It provides a basis for chemists to interpret mass spectra to solve particular structural problems.The Second Edition has been updated with modern techniques and data handling. Beginning with an introduction to the principles and instrumentation, it then sequentially explains the processes that occur in the mass spectrometer following ionization. The book is unique in the large number of mass spectra presented and provides examples of mass spectra from a wide variety of organic chemicals, concentrating on the relationships between fragmentation patterns, common chemical reactions, and chemical structures. The book also discusses mass spectra obtained with softer ionization techniques, which provide definitive information regarding molecular weights.The text describes mass spectra produced by electron ionization, discussing how the spectral peak pattern relates to molecular structure. It details the use of high-resolution and accurate mass measurement to determine elemental composition of ions in order to identify unknown substances. The book also introduces some of the recent techniques that can be employed to extend the usefulness of mass spectrometry to high molecular weight substances and more polar substances. 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.

A prevalent and increasingly important issue, arsenic removal continues to be one of the most important areas of water treatment. Conventional treatment plants may employ several methods for removing arsenic from water. Commonly used processes include oxidation, sedimentation, coagulation and filtration, lime treatment, adsorption onto sorptive media, ion exchange, and membrane filtration. However, in the most affected regions, large conventional treatment plants may not be appropriate and factors such as cost and acceptability as well as performance must be considered. This book, published in cooperation with leading experts in this field, provides a thorough analysis of the problems, solutions, and possible alternatives to achieve safe water production on a global scale.
