This book presents a unique collection of up-to-date UPLC-MS/MS (ultra performance liquid chromatography-tandem mass spectrometric) methods for the separation and quantitative determination of pesticides, capsaicinoids, heterocyclic amines, aflatoxin, perfluorochemicals, acrylamide, procyanidins and alkaloids, lactose content, phenolic compounds, vitamins, and aroma and flavor compounds in a wide variety of foods and food products. With contributions by experts in interdisciplinary fields, this reference offers practical information for readers in research and development, production, and routing analysis of foods and food products.

This volume explores the different approaches and techniques used by researchers to study the recent challenges and developments in metabolic profiling. This book is divided into IV parts. Part I contains chapters that highlight basic concepts, such as experimental design, data treatment, metabolite identification, and harmonization. Part II describes experimental protocols for both targeted and untargeted metabolomics covering the basic analytical technologies: LC-MS, GC-MS, NMR and CE-MS. In addition the protocols describe methods for the study of tissues, feces, blood and other types of biological samples as well as the application of chemical derivatization for GC-MS. Parts III and IV present the use of metabolomics in the study of food, plants and the life sciences, with examples from the quest for the discovery of disease biomarkers, physical exercise omics and metabolic profiling of food, fruit and wine. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and thorough, Metabolic Profiling: Methods and Protocols is a valuable resource for researchers who are interested in expanding their knowledge of this rapidly developing field.

The porphyrins, chlorophylls, bilins and related tetrapyrroles are vital for all living organisms. Natural and synthetic tetrapyrroles are used extensively in foods, cosmetics, biotechnology, pharmaceuticals, diagnostics and medicine. Methods for their separation and characterization therefore, have a very wide area of applications. Yet, there is a dearth of books dedicated to HPLC and HPLC/MS of tetrapyrroles. Lim addresses this problem admirably by providing practical HPLC and HPLC/MS protocols coupled with in-depth chromatographic and mass spectrometric reference data. These are invaluable in the analysis, identification and characterization of porphyrins, chlorophylls, bilins and other related compounds found in biological and clinical materials. HPLC method development and optimization for coupling to mass spectrometry are also described in rich detail. Sample preparation, and suggestions for avoiding procedural artifacts during extraction of clinical and biological samples are discussed. Clinical biochemists involved in biochemical diagnosis of human porphyrias will find this monograph assuredly helpful, as would analysts, biochemists and chemists involved in the separation, isolation and characterization of natural and synthetic tetrapyrroles. Undoubtedly, Lim has contributed a master-piece containing sufficient background material for beginners and up-to-date references for all researchers in the field.

An in-depth text that explores the interface between analytical chemistry and trace evidence Analytical Techniques in Forensic Science is a comprehensive guide written in accessible terms that examines the interface between analytical chemistry and trace evidence in forensic science. With contributions from noted experts on the topic, the text features a detailed introduction analysis in forensic science and then subsequent chapters explore the laboratory techniques grouped by shared operating principles. For each technique, the authors incorporate specific theory, application to forensic analytics, interpretation, forensic specific developments, and illustrative case studies. Forensic techniques covered include UV-Vis and vibrational spectroscopy, mass spectrometry and gas and liquid chromatography. The applications reviewed include evidence types such as fibers, paint, drugs and explosives. The authors highlight data collection, subsequent analysis, what information has been obtained and what this means in the context of a case. The text shows how analytical chemistry and trace evidence can problem solve the nature of much of forensic analysis. This important text: Puts the focus on trace evidence and analytical science Contains case studies that illustrate theory in practice Includes contributions from experts on the topics of instrumentation, theory, and case examples Explores novel and future applications for analytical techniques Written for undergraduate and graduate students in forensic chemistry and forensic practitioners and researchers, Analytical Techniques in Forensic Science offers a text that bridges the gap between introductory textbooks and professional level literature.

Handbook of Advanced Chromatography /Mass Spectrometry Techniques is a compendium of new and advanced analytical techniques that have been developed in recent years for analysis of all types of molecules in a variety of complex matrices, from foods to fuel to pharmaceuticals and more. Focusing on areas that are becoming widely used or growing rapidly, this is a comprehensive volume that describes both theoretical and practical aspects of advanced methods for analysis. Written by authors who have published the foundational works in the field, the chapters have an emphasis on lipids, but reach a broader audience by including advanced analytical techniques applied to a variety of fields. Handbook of Advanced Chromatography / Mass Spectrometry Techniques is the ideal reference for those just entering the analytical fields covered, but also for those experienced analysts who want a combination of an overview of the techniques plus specific and pragmatic details not often covered in journal reports. The authors provide, in one source, a synthesis of knowledge that is scattered across a multitude of literature articles. The combination of pragmatic hints and tips with theoretical concepts and demonstrated applications provides both breadth and depth to produce a valuable and enduring reference manual. It is well suited for advanced analytical instrumentation students as well as for analysts seeking additional knowledge or a deeper understanding of familiar techniques. Includes UHPLC, HILIC, nano-liquid chromatographic separations, two-dimensional LC-MS (LCxLC), multiple parallel MS, 2D-GC (GCxGC) methodologies for lipids analysis, and more Contains both practical and theoretical knowledge, providing core understanding for implementing modern chromatographic and mass spectrometric techniques Presents chapters on the most popular and fastest-growing new techniques being implemented in diverse areas of research
