Basic Chemometric Techniques In Atomic Spectroscopy

Download or read book Basic Chemometric Techniques in Atomic Spectroscopy written by Jose Andrade-Garda and published by Royal Society of Chemistry. This book was released on 2015-11-09 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Handbook of Mineral Elements in Food written by de la Guardia and published by John Wiley & Sons. This book was released on 2015-04-20 with total page 792 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Atomic Absorption Spectrometry written by Alfredo Sanz-Medel and published by Momentum Press. This book was released on 2014-08-05 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atomic Absorption Spectroscopy (AAS) is a well-established elemental analysis technology. It remains one of the most popular and cost-effective analysis tools used by chemists, physicists, and materials scientists worldwide. This second edition offers a concise introduction to AAS concepts, essential methodologies, and important applications. It has been comprehensively updated for the latest advances in AAS techniques and instruments. Highlights include: • Overviews of all basic atomic absorption concepts, including atomic line spectra theory, common sampling techniques, radiation sources, spectrometers, and detectors; • Coverage of hydride generation, cold vapor generation and electrothermal generation, as well as flow injection analysis (FIA) to enhance AAS analytical performance; • New sections on troubleshooting and quality control guidelines, chemometrics, and emerging fields of applications, including analysis of nanoparticles; and • Selected examples of standards for chemical analysis.

Download or read book Chemometrics in Spectroscopy written by Howard Mark and published by Academic Press. This book was released on 2018-07-13 with total page 1092 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemometrics in Spectroscopy, Second Edition, provides the reader with the methodology crucial to apply chemometrics to real world data. It allows scientists using spectroscopic instruments to find explanations and solutions to their problems when they are confronted with unexpected and unexplained results. Unlike other books on these topics, it explains the root causes of the phenomena that lead to these results. While books on NIR spectroscopy sometimes cover basic chemometrics, they do not mention many of the advanced topics this book discusses. In addition, traditional chemometrics books do not cover spectroscopy to the point of understanding the basis for the underlying phenomena. The second edition has been expanded with 50% more content covering advances in the field that have occurred in the last 10 years, including calibration transfer, units of measure in spectroscopy, principal components, clinical data reporting, classical least squares, regression models, spectral transfer, and more. - Written in the column format of the authors' online magazine - Presents topical and important chapters for those involved in analysis work, both research and routine - Focuses on practical issues in the implementation of chemometrics for NIR Spectroscopy - Includes a companion website with 350 additional color figures that illustrate CLS concepts

Download or read book Laser-Induced Breakdown Spectroscopy written by Jagdish P. Singh and published by Elsevier. This book was released on 2020-06-02 with total page 624 pages. Available in PDF, EPUB and Kindle. Book excerpt: Laser-Induced Breakdown Spectroscopy, Second Edition, covers the basic principles and latest developments in instrumentation and applications of Laser Induced Breakdown Spectroscopy (LIBS). Written by active experts in the field, it serves as a useful resource for analytical chemists and spectroscopists, as well as graduate students and researchers engaged in the fields of combustion, environmental science, and planetary and space exploration. This fully revised second edition includes several new chapters on new LIBS techniques as well as several new applications, including flame and off-gas measurement, pharmaceutical samples, defense applications, carbon sequestration and site monitoring, handheld instruments, and more. LIBS has rapidly developed into a major analytical technology with the capability of detecting all chemical elements in a sample, of real- time response, and of close-contact or stand-off analysis of targets. It does not require any sample preparation, unlike conventional spectroscopic analytical techniques. Samples in the form of solids, liquids, gels, gases, plasmas, and biological materials (like teeth, leaves, or blood) can be studied with almost equal ease. This comprehensive reference introduces the topic to readers in a simple, direct, and accessible manner for easy comprehension and maximum utility. - Covers even more applications of LIBS beyond the first edition, including combustion, soil physics, environment, and life sciences - Includes new chapters on LIBS techniques that have emerged in the last several years, including Femtosecond LIBS and Molecular LIBS - Provides inspiration for future developments in this rapidly growing field in the concluding chapter
