Chemometrics in Analytical Spectroscopy 2nd Edition provides a tutorial approach to the development of chemometric techniques and their application to the interpretation of analytical spectroscopic data. From simple descriptive statistics to the more sophisticated modelling techniques of principal components analysis and partial least squares regression, this updated edition provides necessary background, enhanced by case studies. The extensive use of worked examples throughout gives Chemometrics in Analytical Spectroscopy 2nd Edition special relevance in teaching and introducing chemometrics to undergraduates and post-graduates. The book is also ideal for analysts with little specialist background. Extracts from reviews of 1st Edition: "Adams has succeeded in providing a text which is focused on analytical spectroscopy and that gently guides the reader through the concepts without recourse to too much matrix algebra." Trends in Analytical Chemistry "...a very good introductory text for those wishing to understand the workings of chemometrics techniques." The Analyst

Klaus Danzers Chemometrik - Grundlagen und Anwendungen füllt eine Lücke im deutschsprachigen Lehrbuchmarkt. Es spannt den Bogen von der uni- und multivarianten Statistik bis hin zu Neuronalen Netzen und Genetischen Algorithmen und konzentriert sich auf die Analyse analytisch-chemischer und chemisch-experimenteller Daten. Es bietet Studenten und bereits in der Praxis tätigen Einsteigern die Möglichkeit, sich in die Grundlagen ohne überflüssigen theoretischen Ballast einzuarbeiten und viele existierende oder potentielle Anwendungsfelder kennenzulernen. Dem Fachmann bietet es einen systematischen, alle Schritte des analytischen Prozesses einschliessenden Überblick; auch Versuchsplanung, Optimierung, Signal- und Bildverarbeitung, Qualitätssicherung und Rentabilitätsbetrachtungen werden ausreichend berücksichtigt. Besonderer Wert wurde auf die Anschaulichkeit, die Darstellung der Zusammenhänge zwischen den Methoden und die Praxisrelevanz gelegt.

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.

Using formal descriptions, graphical illustrations, practical examples, and R software tools, Introduction to Multivariate Statistical Analysis in Chemometrics presents simple yet thorough explanations of the most important multivariate statistical methods for analyzing chemical data. It includes discussions of various statistical methods, such as principal component analysis, regression analysis, classification methods, and clustering. Written by a chemometrician and a statistician, the book reflects the practical approach of chemometrics and the more formally oriented one of statistics. To enable a better understanding of the statistical methods, the authors apply them to real data examples from chemistry. They also examine results of the different methods, comparing traditional approaches with their robust counterparts. In addition, the authors use the freely available R package to implement methods, encouraging readers to go through the examples and adapt the procedures to their own problems. Focusing on the practicality of the methods and the validity of the results, this book offers concise mathematical descriptions of many multivariate methods and employs graphical schemes to visualize key concepts. It effectively imparts a basic understanding of how to apply statistical methods to multivariate scientific data.

Chemometrics is the chemical discipline that uses mathematical, statistical and other methods employing formal logic: to design or select optimal measurement procedures and experiments, and - to provide maximum relevant chemical information by analysing chemical data. Being conceived as a branch of analytical chemistry, chemometrics now is a general approach. It extracts relevant information out of measured data, regardless of their origin: chemical, physical, biological, etc. Chemometrics has been applied in different areas, and most successfully in multivariate calibration, pattern recognition, classification and discriminant analysis, multivariate modelling, and monitoring of processes. The main chemometric principle is a concept of hidden data structures that can be found using methods of multivariate data analysis. These are the well-known statistic tools such as partial least squares (PLS), soft independent modelling of class analogy (SIMCA), principal-component regression (PCR), wavelet analysis, and many others. development of new methods for manipulating multivariate data; and new applications of the known chemometric techniques in different areas such as environment control, food industry, agriculture, medicine, and engineering.

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
