Available in PDF, EPUB and Kindle. Book excerpt: Instrumental Methods in Food Analysis is aimed at graduate students in the science, technology and engineering of food and nutrition who have completed an advanced course in food analysis. The book is designed to fit in with one or more such courses, as it covers the whole range of methods applied to food analysis, including chromatographic techniques (HPLC and GC), spectroscopic techniques (AA and ICP), electroanalytical and electrophoresis techniques. No analysis can be made without appropriate sample preparation and in view of the present economic climate, the search for new ways to prepare samples is becoming increasingly important. Guided by the need for environmentally-friendly technologies, the editors chose two, relatively new techniques, the microwave-assisted processes (MAPTM (Chapter 10) and supercritical fluid extraction (Chapter 11). Features of this book: - is one the few academic books on food analysis specifically designed for a one semester or one year course -it contains updated information - the coverage gives a good balance between theory, and applications of techniques to various food commodities. The chapters are divided into two distinct sections: the first is a description of the basic theory regarding the technique and the second is dedicated to a description of examples to which the reader can relate in his/her daily work.

Download or read book Hazardous Metals in the Environment written by M. Stoeppler and published by Elsevier. This book was released on 1992-04-13 with total page 553 pages. Available in PDF, EPUB and Kindle. Book excerpt: The execution of detailed studies on the fate and levels of hazardous elements in the environment, foodstuffs and in human beings has become a major task in environmental research and especially in analytical chemistry. This has led to a demand to develop new methodology and optimize that already in use. The book offers the reader a general introduction to the problem areas that are currently being tackled, followed by chapters on sampling and sample preservation, strategies and applications of the archiving of selected representative specimens for long-term storage in environmental specimen banks. This is supplemented by the example of wine as a preserved - frequently, already historical - specimen which clearly reflects technological changes over time. The following chapters review sample treatment, present an overview on the most frequently and successfully applied trace analytical methods for metals and metal compounds, and introduce the increasingly important methods for identifying and quantifying metal species in sediments and soils (speciation). The chapters in the second part of the book provide data on analytical methods for determining the levels of toxicologically, ecotoxicologically and ecologically important elements in environmental and biological materials, including information on the separation and quantification of chemical and organomatallic species. The elements treated are aluminium, arsenic, cadmium, chromium, cobalt, lead, mercury, nickel, selenium and thallium. The final chapter treats quality assurance and the importance of the continuous use of appropriate reference materials to avoid erroneous results.

Download or read book Instrumental Analytical Chemistry written by James W. Robinson and published by CRC Press. This book was released on 2021-06-29 with total page 920 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analytical chemistry today is almost entirely instrumental analytical chemistry and it is performed by many scientists and engineers who are not chemists. Analytical instrumentation is crucial to research in molecular biology, medicine, geology, food science, materials science, and many other fields. With the growing sophistication of laboratory equipment, there is a danger that analytical instruments can be regarded as "black boxes" by those using them. The well-known phrase "garbage in, garbage out" holds true for analytical instrumentation as well as computers. This book serves to provide users of analytical instrumentation with an understanding of their instruments. This book is written to teach undergraduate students and those working in chemical fields outside analytical chemistry how contemporary analytical instrumentation works, as well as its uses and limitations. Mathematics is kept to a minimum. No background in calculus, physics, or physical chemistry is required. The major fields of modern instrumentation are covered, including applications of each type of instrumental technique. Each chapter includes: A discussion of the fundamental principles underlying each technique Detailed descriptions of the instrumentation. An extensive and up to date bibliography End of chapter problems Suggested experiments appropriate to the technique where relevant This text uniquely combines instrumental analysis with organic spectral interpretation (IR, NMR, and MS). It provides detailed coverage of sampling, sample handling, sample storage, and sample preparation. In addition, the authors have included many instrument manufacturers’ websites, which contain extensive resources.

Available in PDF, EPUB and Kindle. Book excerpt: This book is an updated, completely revised version of a previous volume in this series entitled: ENVIRONMENTAL ANALYSIS -- Techniques, applications and quality assurance. The book treats different aspects of environmental analysis such as sample handling and analytical techniques, the applications to trace analysis of pollutants (mainly organic compounds), and quality assurance aspects, including the use of certified reference materials for the quality control of the whole analytical process. New analytical techniques are presented that have been developed significantly over the last 6 years, like solid phase microextraction, microwave-assisted extraction, liquid chromatography-mass spectrometric methods, immunoassays, and biosensors. The book is divided into four sections. The first describes field sampling techniques and sample preparation in environmental matrices: water, soil, sediment and biota. The second section covers the application areas which are either based on techniques, like the use of gas chromatography-atomic emission detection, immunoassays, or coupled-column liquid chromatography, or on specific application areas, like chlorinated compounds, pesticides, phenols, mycotoxins, phytotoxins, radionuclides, industrial effluents and wastes, including mine waste. Validation and quality assurance are described in the third section, together with the interpretation of environmental data using advanced chemometric techniques. The final section reports the use of somewhat advanced analytical methods, usually more expensive, less routinely used or less developed, for the determination of pollutants.

Download or read book Nuclear Analytical Techniques in Medicine written by R. Cesareo and published by Elsevier. This book was released on 2011-09-22 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book will acquaint the interested physician or physicist with the fundamental principles and the instrumentation relevant to analytical techniques based on atomic and nuclear physics, as well as present and future biomedical applications. Besides providing a theoretical description of the physical phenomena, a large part of the book is devoted to applications in the medical and biological field, particularly in haematology, forensic medicine and environmental science.Analysis of the elemental composition of human tissues and cells and in particular trace elements has attracted increasing interest over the last few years, due to the increase in knowledge on the role of some elements and the possible correlations between abnormal concentrations of one or more trace elements and pathological conditions. This has stimulated the development of analytical techniques which allow the detection of trace elements simultaneously and at very low concentrations. Particularly in methods involving nuclear principles or nuclear apparatus, many techniques have been largely and successfully developed in recent years and applied in the medical field. This volume reviews methods such as the possibility of carrying out rapid multi-element analysis of trace elements on biomedical samples, in vitro and in vivo, by XRF-analysis; the ability of the PIXE-microprobe to analyze in detail and to map trace elements in fragments of biomedical samples or inside the cells; the potentiality of in vivo nuclear activation analysis for diagnostic purposes. Finally, techniques are described such as radiation scattering (elastic and inelastic scattering) and attenuation measurements which will undoubtedly see great development in the immediate future.
