Chemometrics in Environmental Analysis


Book Description

J. W. Einax, H. W. Zwanziger S. Gei Chemometrics in Environmental Analysis Make the most of your data! This new title will serve both as an introduction and as a practical guide to those techniques of chemometrics which are applicable to environmental analysis. By describing the optimum methods of data analysis it will help all chemists in this field to save time and money. Because the authors demonstrate the most important chemometric methods with the aid of numerous examples, the reader will learn to solve a given problem by use of the appropriate method. Applications range from sampling, through laboratory analysis, to evaluation. Interpretation of the findings is explained clearly. The text covers not only basic methods such as univariate statistics, regression analysis, and statistical test planning, but also multivariate data analysis, for example, cluster analysis, principal components analysis, and factor and discriminant analysis. Case studies show the enormous possibilities, and the limits, of chemometric methods. The book will help all environmental analytical scientists, even those with only a basic knowledge of mathematics, to optimize the evaluation and interpretation of the results of their measurements.

Chemometrics in Spectroscopy


Book Description

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




Contaminant Levels and Ecological Effects


Book Description

This volume uses chemometric mathematical modelling approaches to investigate geographic areas at risk of ecological degradation due to pollution. While most analytical approaches in environmental research involve sophisticated and sensitive instrumental techniques, this book employs chemometric techniques to create a corresponding data matrix to extract accurate and realistic environmental information in areas vulnerable to and affected by hazardous substances. The text offers case studies to establish a general framework of the opportunities, advantages, weaknesses and challenges of these mathematical approaches, and provides a chemometric model of each focus area to assess the long-distance distribution of pollutants. The case studies highlight the potential use of novel chemometric models for mitigating and preventing environmental pollution and ecological risks, while also providing reviews of the current status and developments in chemometric analysis of environmental pollution. The book will be of interest to students and researchers in environmental and agricultural chemistry, environmental pollution modelling and ecological degradation.
