The analysis of drugs and their metabolites in biological media are now expected to routinely achieve ± 20% accuracy in the ng/mL concentration level. Therefore, the availability and the selection of quality ion-pairs designating the analytes and their isotopically labeled analogs (ILAs) are important considerations in achieving the accuracy of quantitation results. Assisting scientists with this process, Quantitation and Mass Spectrometric Data of Drugs and Isotopically Labeled Analogs provides an extremely valuable reference for labs involved in the analysis of therapeutic and abused drugs. Part One of this comprehensive volume illustrates approaches, mechanisms, and challenges pertaining to the use of isotopic analogs as internal standards for drug quantitation. The second section is a systematic compilation of full-scan mass spectra of drugs and their analogs, as parent compounds and as derivatives resulting from various chemical derivatization approaches, commonly encountered in today’s labs. Based on the mass spectra data presented in the second section, Part Three provides corresponding tables of ion-pairs which can potentially be adapted to designate the drugs and their isotopic analogs in the analytical processes. Relative quality of these ion-pairs (cross-contribution to the intensity of these ions by their isotopic analogs) is included in these tables. With more than 1500 full-scan mass spectra and quick access data tables, this text represents the authors’ years of work compiling mass spectra of the many chemical derivatization forms of drugs, their metabolites, and their isotopically labeled counterparts. The unparalleled scope of this compilation makes it a critical one-stop reference for those involved in drug analyses of biological specimens and interpretation of results.

Advances in analytical chemistry methodology now allow us to detect the most minute trace amounts of pesticides. As this capacity grows, so does public concern about toxic contamination, resulting in stricter government regulations and a growing demand for even more sensitive, precise, and reliable analysis. Addressing the interplay between regulations and the development of analytical technology, this volume presents the first unified treatment of the regulatory and analytical aspects of pesticide residues. Current regulations, existing and emerging methodologies, state-of-the-art instrumentation, and the basic science of analyzing for pesticides in food and other environmental media are all covered. The book provides step-by-step guidelines to analytical techniques, along with real-world examples from the latest research-showing the reader how to analyze minute traces of pesticides quickly and accurately, using both highly sophisticated and basic, less sensitive techniques. Many safety issues are explored in depth, as are the regulatory aspects of pesticide registration, residue analysis, exposure monitoring, risk assessment, and tolerance enforcement. Timely, authoritative, and practical throughout, Pesticide Residues in Foods is an invaluable reference for analytical chemists and laboratory managers everywhere-in industry, agriculture, environmental sciences, research, and instrument manufacturing-and for anyone with an interest in the broader environmental, agricultural, and consumer-related implications of pesticide use. An invaluable resource for analytical chemists and laboratory managers, Pesticide Residues in Foods provides a complete overview of the theory, practice, and regulatory aspects of pesticide residue analysis today, including: * All regulatory issues, from risk assessment and tolerance to data-quality requirements to laboratory accreditation standards * State-of-the-art methodologies and instrumentation, including high- performance liquid chromatography and mass spectrometry * The application of analytical technology to "green chemistry," such as the reduction of solvents and toxic reagents in the laboratory * Novel solutions to the old problem of keeping the food supply safe from harmful levels of pesticides * Ample examples to help analytical chemists select the most appropriate method for a given residue analysis * Easy-to-use tables and figures throughout the text
