Basic Chemometric Techniques In Atomic Spectroscopy

This is the first book for atomic spectroscopists to present the basic principles of experimental designs, optimization and multivariate regression. Multivariate regression is a valuable statistical method for handling complex problems (such as spectral and chemical interferences) which arise during atomic spectrometry. However, the technique is underused as most spectroscopists do not have time to study the often complex literature on the subject. This practical introduction uses conceptual explanations and worked examples to give readers a clear understanding of the technique. Mathematics is kept to a minimum but, when required, is kept at a basic level.

The first edition of this book was a first book for atomic spectroscopists to present the basic principles of experimental designs, optimization and multivariate regression. Multivariate regression is a valuable statistical method for handling complex problems (such as spectral and chemical interferences) which arise during atomic spectrometry. However, the technique is underused as most spectroscopists do not have time to study the often complex literature on the subject. This practical introduction uses conceptual explanations and worked examples to give readers a clear understanding of the technique. Mathematics is kept to a minimum but, when required, is kept at a basic level. Practical considerations, interpretations and troubleshooting are emphasized and literature surveys are included to guide the reader to further work. The same dataset is used for all chapters dealing with calibration to demonstrate the differences between the different methodologies. Readers will learn how to handle spectral and chemical interferences in atomic spectrometry in a new, more efficient and cost-effective way.

This practical introduction is the first to present the principles of experimental designs, optimization and multivariate regression for atomic spectroscopists.

This book describes both the theory of atomic spectroscopy and all the major atomic spectrometric techniques (AAS, Flame-AES, Plasma AES, AFS, and ICP-MS), including basic concepts, instrumentation and applications. Spectrochemical Analysis by Atomic Absorption and Emission is very wide in scope and will be extremely useful to both undergraduates and lecturers undertaking modern analytical chemistry courses. It contains many figures and tables which illuminate the text, covers various sample preparation methods and gives suggestions for further reading.

This textbook is an outgrowth of the author's experience in teaching a course, primarily to graduate students in chemistry, that included the subject matter presented in this book. The increasing use and importance of atomic spectroscopy as an analytical tool are quite evident to anyone involved in elemental analysis. A number of books are available that may be considered treatises in the various fields that use atomic spectra for analytical purposes. These include areas such as arc-spark emission spectroscopy, flame emission spectroscopy, and atomic absorption spectroscopy. Other books are available that can be catalogued as "methods" books. Most of these books serve well the purpose for which they were written but are not well adapted to serve as basic textbooks in their fields. This book is intended to fill the aforementioned gap and to present the basic principles and instrumentation involved in analytical atomic spectro scopy. To meet this objective, the book includes an elementary treatment of the origin of atomic spectra, the instrumentation and accessory equipment used in atomic spectroscopy, and the principles involved in arc-spark emission, flame emission, atomic absorption, and atomic fluorescence. The chapters in the book that deal with the methods of atomic spectro scopy discuss such things as the basic principles involved in the method, the instrumentation requirements, variations of instrumentation, advantages and disadvantages of the method, problems of interferences, detection limits, the collection and processing of the data, and possible applications.

Mineral elements are found in foods and drink of all differenttypes, from drinking water through to mothers’ milk. Thesearch for mineral elements has shown that many trace andultratrace-level elements presented in food are required for ahealthy life. By identifying and analysing these elements, it ispossible to evaluate them for their specific health-givingproperties, and conversely, to isolate their less desirableproperties with a view to reducing or removing them altogether fromsome foods. The analysis of mineral elements requires a number ofdifferent techniques – some methods may be suitable for onefood type yet completely unsuited to another. The Handbook of Mineral Elements in Food is the firstbook to bring together the analytical techniques, the regulatoryand legislative framework, and the widest possible range of foodtypes into one comprehensive handbook for food scientists andtechnologists. Much of the book is based on the authors’ owndata, most of which is previously unpublished, making theHandbook of Mineral Elements in Food a vital andup-to-the-minute reference for food scientists in industry andacademia alike. Analytical chemists, nutritionists and food policymakers will also find it an invaluable resource. Showcasing contributions from international researchers, andconstituting a major resource for our future understanding of thetopic, the Handbook of Mineral Elements in Food is anessential reference and should be found wherever food science andtechnology are researched and taught.

"Provides a thorough, up-to-date survey of techniques for elemental analysis--including atomic absorption spectroscopy, atomic fluorescence, flame photometry, emission spectroscopy, and plasma emission. Second Edition includes expanded material on interfaced plasma-mass spectrometry (ICP-MS), diode arrays, and other emerging spectroscopic fields."
