Book Description
The book reviews the basic concepts and highlights the most relevant advances and developments that have taken place in the field of comprehensive two dimensional gas chromatography (GC x GC) since its introduction in 1991. The several instrumental and technical approaches assayed and developed during these seventeen years and that have contributed to the development of this powerful separation technique and to its increasing application in many areas is explained and comprehensively illustrated through a number of chapters devoted these specific topics. More specialized aspects of the technique, including theoretical aspects, modelization of the chromatographic process, software developments, and alternative couplings is also covered. Finally, special attention is paid to data treatment, for both qualitative and quantitative analysis. This book will be a practical resource that will explain from basic to specialized concepts of GC x GC and will show the current state-of-the-art and discuss future trends of this technique. - Outlines basic concepts and principles of GCxGC technique for non-specialists to apply the technique to their research - Provides detailed descriptions of recent technical advances and serves as an instructional guide in latest applications in GCxGC - Sets the scene for possible future development and alternative new applications of technique

Book Description
Nutrients have been recognized as essential for maximum growth, successful reproduction, and infection prevention since the 1940s; since that time, the lion's share of nutrient research has focused on defining their role in these processes. Around 1990, however, a major shift began in the way that researchers viewed some nutrients particularly the vitamins. This shift was motivated by the discovery that modest declines in vitamin nutritional status are associated with an increased risk of ill-health and disease (such as neural tube defects, heart disease, and cancer), especially in those populations or individuals who are genetically predisposed. In an effort to expand upon this new understanding of nutrient action, nutritionists are increasingly turning their focus to the mathematical modeling of nutrient kinetic data. The availability of suitably-tagged (isotope) nutrients (such as B-carotene, vitamin A, folate, among others), sensitive analytical methods to trace them in humans (mass spectrometry and accelerator mass spectrometry), and powerful software (capable of solving and manipulating differential equations efficiently and accurately), has allowed researchers to construct mathematical models aimed at characterizing the dynamic and kinetic behavior of key nutrients in vivo in humans at an unparalleled level of detail.

Book Description
Written by expert contributors from the academic and industrial sectors, this book presents traditional and modern approaches to polymer characterization and analysis. The emphasis is on pragmatics, problem solving and property determination; real-world applications provide a context for key concepts. The characterizations focus on organic polymer and polymer product microstructure and composition. - Approaches molecular characterization and analysis of polymers from the viewpoint of problem-solving and polymer property characterization, rather than from a technique championing approach - Focuses on providing a means to ascertaining the optimum approach or technique(s) to solve a problem/measure a property, and thereby develop an analytical competence in the molecular characterization and analysis of real-world polymer products - Provides background on polymer chemistry and microstructure, discussions of polymer chain, morphology, degradation, and product failure and additive analysis, and considers the supporting roles of modeling and high-throughput analysis

Book Description
This book provides basic coverage of the fundamentals and principles of green chemistry as it applies to chemical analysis. The main goal of Green Analytical Chemistry is to avoid or reduce the undesirable environmental side effects of chemical analysis, while preserving the classic analytical parameters of accuracy, sensitivity, selectivity, and precision. The authors review the main strategies for greening analytical methods, concentrating on minimizing sample preparation and handling, reducing solvent and reagent consumption, reducing energy consumption, minimizing of waste, operator safety and the economic savings that this approach offers. Suggestions are made to educators and editors to standardize terminology in order to facilitate the identification of analytical studies on green alternatives in the literature because there is not a wide and generalized use of a common term that can group efforts to prevent waste, avoid the use of potentially toxic reagents or solvents and those involving the decontamination of wastes. - provides environmentally-friendly alternatives to established analytical practice - focuses on the cost-saving opportunities offered - emphasis on laboratory personnel safety

Book Description
Pharmaceutically active substances are a class of new, so-called "emerging" contaminants that have raised great concern in recent years. Human and veterinary drugs are constantly being introduced into the environment, mainly as a result of the manufacturing process. Over time, this level of chemical input may lead to long-term concentrations and promote continual, but unnoticed adverse effects on aquatic and terrestrial organisms. Analysis, Fate and Removal of Pharmaceuticals in the Water Cycle discusses state-of-the-art analytical methods for trace determination of pharmaceuticals in environmental samples while reviewing the fate and occurrence of pharmaceuticals in the water cycle (elimination in wastewater and drinking water treatment). Focus is given to the newest developments in the treatment technologies, such as membrane bioreactors and advance oxidation processes.* Well-structured overview of latest developments in trace determination* Concise and critical compilation of literature published over the past few years * Focuses on new treatment technologies, such as membrane bioreactors and advance oxidation processes.

Book Description
Food Contaminants and Residue Analysis treats different aspects of the analysis of contaminants and residues in food and highlights some current concerns facing this field. The content is initiated by an overview on food safety, the objectives and importance of determining contaminants and residues in food, and the problems and challenges associated to these analyses. This is followed by full details of relevant EU and USA regulations. Topics, such as conventional chromatographic methods, accommodating cleanup, and preparing substances for further instrumental analysis, are encompassed with new analytical techniques that have been developed, significantly, over the past few years, like solid phase microextraction, liquid chromatography-mass spectrometry, immunoassays, and biosensors. A wide range of toxic contaminants and residues, from pesticides to mycotoxins or dioxins are examined, including polychlorinated biphenyls, polycyclic aromatic hydrocarbons, N-nitrosamines, heterocyclic amines, acrylamide, semicarbazide, phthalates and food packing migrating substances. This book can be a practical resource that offers ideas on how to choose the most effective techniques for determining these compounds as well as on how to solve problems or to provide relevant information. Logically structured and with numerous examples, Food Contaminants and Residue Analysis will be valuable a reference and training guide for postgraduate students, as well as a practical tool for a wide range of experts: biologists, biochemists, microbiologists, food chemists, toxicologists, chemists, agronomists, hygienists, and everybody who needs to use the analytical techniques for evaluating food safety.
