Book Description
Although sampling errors inevitably lead to analytical errors, the importance of sampling is often overlooked. The main purpose of this book is to enable the reader to identify every possible source of sampling error in order to derive practical rules to (a) completely suppress avoidable errors, and (b) minimise and estimate the effect of unavoidable errors. In short, the degree of representativeness of the sample can be known by applying these rules. The scope covers the derivation of theories of probabilistic sampling and of bed-blending from a complete theory of heterogeneity which is based on an original, very thorough, qualitative and quantitative analysis of the concepts of homogeneity and heterogeneity. All sampling errors result from the existence of one form or another of heterogeneity. Sampling theory is derived from the theory of heterogeneity by application of a probabilistic operator to a material whose heterogeneity has been characterized either by a simple scalar (a variance: zero-dimensional batches) or by a function (a variogram: one-dimensional batches). A theory of bed-blending (one-dimensional homogenizing) is then easily derived from the sampling theory. The book should be of interest to all analysts and to those dealing with quality, process control and monitoring, either for technical or for commercial purposes, and mineral processing. Although this book is primarily aimed at graduates, large portions of it are suitable for teaching sampling theory to undergraduates as it contains many practical examples provided by the author's 30-year experience as an international consultant. The book also contains useful source material for short courses in Industry.

Book Description
Fundamentals of Analytical Chemistry are usually presented as a sum of chemical and physical foundations, laws, axioms and equations for analytical methods and procedures. In contrast, this book delivers a practice-oriented, general guiding theory valid for all methods and techniques. The metrological foundations included define strictly the figures of merit in order to minimize confusions still appearing in Analytical Chemistry publications today.

Book Description
Companies often struggle to turn successful research into viable commercial products, processes and systems. This book defines technology development and reveals methods to successfully evaluate, fund and commercialize a technology. Cases studies help the reader evaluate the connection between a technology and potential markets, set useful hypotheses, develop statistically valid conclusions, and apply those conclusions to business goals.

Book Description
Quality assurance and accreditation in analytical chemistry laboratories is an important issue on the national and international scale. The book presents currently used methods to assure the quality of analytical results and it describes accreditation procedures for the mutual recognition of these results. The book describes in detail the accreditation systems in 13 European countries and the present situation in the United States of America. The editor also places high value on accreditation and certification practice and on the relevant legislation in Europe. The appendix lists invaluable information on important European accreditation organizations.

Book Description
Introducing the principles, practice and applications of mass spectrometric techniques in the study of natural substances in foods, this book conveys the depth and breadth of modern mass spectrometry in relation to food analysis. It covers traditional techniques such as electron and chemical ionisation and newer soft ionisation techniques such as matrix-assisted laser desorption ionisation and electrospray. All of these techniques are especially relevant in food quality and safety studies and in biopolymer analysis. The ability to analyse biopolymers by mass spectrometry is having a major impact on the study of food structure components, food proteins, food pathogens and food components produced from genetically modified organisms. The principles and practice of mass spectrometry are covered in the early chapters and are followed by applications in flavour analysis and the determination of non-nutrient, biologically-active, natural substances in foods. The analysis and metabolic studies of amino acids, peptides, proteins, lipids, sugars, carbohydrates and vitamins is also discussed, with separate chapters on mineral and micronutrient metabolism and techniques of pyrolysis mass spectrometry. Mass Spectrometry of Natural Substances in Food will be a valuable resource for food scientists, food analysts and others working in food research, nutrition and safety.

Book Description
In analytical chemistry and pharmaceutical technology attention is increasingly focussed on improving the quality of methods and products. This book aims at fostering the awareness of the potential of existing mathematical and statistical methods to improve this quality. It provides procedures and ideas on how to make a product or a method less sensitive to small variations in influencing factors. Major issues covered are robustness and stability improvement and ruggedness testing. General strategies and a theoretical introduction to these methods are described, and thorough overviews of methods used in both application areas and descriptions of practical applications are given.Features of this book:• Gives a good overview of mathematical and statistical methods used in two application areas, i.e. pharmaceutical technology and analytical chemistry• Illustrates the different approaches available to attain robustness• Gives ideas on how to use methods in practical situations.The book is intended for those who develop and optimize, and are responsible for the overall quality of, analytical methods and pharmaceutical technological products and procedures.

Book Description
A method for organizing and conducting scientific experiments is described in this volume which enables experimenters to reduce the number of trials run, while retaining all the parameters that may influence the result. The choice of ideal experiments is based on mathematical concepts, but the author adopts a practical approach and uses theory only when necessary. Written for experimenters by an experimenter, it is an introduction to the philosophy of scientific investigation. Researchers with limited time and resources at their disposal will find this text a valuable guide for solving specific problems efficiently. The presentation makes extensive use of examples, and the approach and methods are graphical rather than numerical. All calculations can be performed on a personal computer; readers are assumed to have no previous knowledge of the subject. The presentation is such that the beginner may acquire a thorough understanding of the basic concepts. However, there is also sufficient material to challenge the advanced student. The book is, therefore, suitable for both first and advanced courses. The many examples can also be used in detail for self-study or as a reference.

Book Description
Analyzing observed or measured data is an important step in applied sciences. The recent increase in computer capacity has resulted in a revolution both in data collection and data analysis. An increasing number of scientists, researchers and students are venturing into statistical data analysis; hence the need for more guidance in this field, which was previously dominated mainly by statisticians.This handbook fills the gap in the range of textbooks on data analysis. Written in a dictionary format, it will serve as a comprehensive reference book in a rapidly growing field. However, this book is more structured than an ordinary dictionary, where each entry is a separate, self-contained entity. The authors provide not only definitions and short descriptions, but also offer an overview of the different topics. Therefore, the handbook can also be used as a companion to textbooks for undergraduate or graduate courses.1700 entries are given in alphabetical order grouped into 20 topics and each topic is organized in a hierarchical fashion. Additional specific entries on a topic can be easily found by following the cross-references in a top-down manner. Several figures and tables are provided to enhance the comprehension of the topics and a list of acronyms helps to locate the full terminologies. The bibliography offers suggestions for further reading.
