Speciation is one of the growing features of analytical chemistry of this decade. It is now widely recognized that the determination of total trace element contents is no longer sufficient - understanding pathways of trace elements depends on specific chemical forms, such as oxidation states, organometallic compounds, etc. However, lack of quality control of speciation often hampers the comparability of data within and between laboratories. Considering the high number of analyses performed by a wide range of EC laboratories, the SM&T programme (formerly BCR) of the European Commission has launched collaborative projects to improve the state-of-the-art of speciation analysis in Europe. Method Performance Studies for Speciation Analysis presents an overview of these recent studies. As well as discussion of the techniques used, their performance as applied to real-case analyses and possible sources of error, the preparation of Certified Reference Materials for the validation of methods used is also described. With its broad coverage and in-depth discussions, which encompass the work of eminent European experts, this unique book will be essential reading for laboratory staff in industry, academia and government.
This Guide is concerned with the practice of qualitative analysis and contains invaluable advice for laboratories undertaking such work. It is designed to assist laboratories in establishing and maintaining a working regime that will minimise the risk of error and maximise the quality of the analytical information they produce. It is aimed primarily at laboratory managers and those responsible for any part of the analysis process from designing qualitative tests or deciding which tests to apply in particular cases to those performing the requisite experimental work. Qualitative Analysis has been developed using the knowledge and experience of an advisory panel drawn from a representative cross-section of practising analytical scientists. It was produced as part of the VAM Programme, and will be a useful guide for laboratory staff, government agencies, researchers and professionals in industry and academia alike.
Our world is widely contaminated with damaging chemicals, and companies create thousands of new, potentially dangerous chemicals each year. Due to the difficulty and expense of obtaining accurate measurements and the unreliability of reported values, we know surprisingly little about the properties of these contaminants. Determining the properties of chemicals is critical to judging their impact on environmental quality and in making decisions about emission rates, clean-up, and other important public health issues. Chemical Property Estimation describes modern methods of estimating chemical properties, methods which cost much less than traditional laboratory techniques and are sufficiently accurate for most environmental applications. Estimation methods are used to screen chemicals for testing, design monitoring and analysis methods, design clean-up procedures, and verify experimental measurements. The book discusses key methods for estimating chemical properties and considers their relative strengths and weaknesses. Several chapters are devoted to the partitioning of chemicals between air, water, soil, and biota; and properties such as solubility, vapor pressure, and chemical transport. Each chapter begins with a review of relevant theory and background information explaining the applications and limitations of each method. Sample calculations and practical advice on how and when to use each method are included as well. Each method is evaluated for accuracy and reliability. Computer software, databases, and internet resources are evaluated, as well as other supplementary material, such as fundamental constants, units of measure, and more.
Because of unique water properties, humidity affects many living organisms, including humans and materials. Humidity control is important in various fields, from production management to creating a comfortable living environment. The second volume of The Handbook of Humidity Measurement is entirely devoted to the consideration of different types of solid-state devices developed for humidity measurement. This volume discusses the advantages and disadvantages about the capacitive, resistive, gravimetric, hygrometric, field ionization, microwave, Schottky barrier, Kelvin probe, field-effect transistor, solid-state electrochemical, and thermal conductivity-based humidity sensors. Additional features include: Provides a comprehensive analysis of the properties of humidity-sensitive materials, used for the development of such devices. Describes numerous strategies for the fabrication and characterization of humidity sensitive materials and sensing structures used in sensor applications. Explores new approaches proposed for the development of humidity sensors. Considers conventional devices such as phsychometers, gravimetric, mechanical (hair), electrolytic, child mirror hygrometers, etc., which were used for the measurement of humidity for several centuries. Handbook of Humidity Measurement, Volume 2: Electronic and Electrical Humidity Sensors provides valuable information for practicing engineers, measurement experts, laboratory technicians, project managers in industries and national laboratories, as well as university students and professors interested in solutions to humidity measurement tasks as well as in understanding fundamentals of any gas sensor operation and development.
Regarded as a seminal work in chemometrics, Information Theory as Applied to Chemical Analysis by Karel Eckscklager and Vladimir Stepanek shed light on the importance of information theory, stressing that the very mechanisms of information gathering are key to the quality of the analytical data collected. Continuing that examination, this new volume, Information Theory in Analytical Chemistry, looks at the practical applications of information theory, especially as a tool for optimizing chemical analysis. Complete with up-to-date examples from diverse areas such as toxicology, environmental science, and metallurgy, the book provides a workable framework for developing, optimizing, and assessing analytical procedures. Layer by layer, the analytical process is dismantled - and reassembled - so the reader develops a genuine, practice-oriented grasp of just how information theory shapes the chemical analysis process. Beginning with the fundamentals of information theory and analytical chemistry, the book then considers the systemic nature of chemical analysis, examining each of its facets: identification of components, trace analysis, qualitative analysis, quantitative analysis, multicomponent analysis, microanalysis, and surface or structure analysis. Up-to-date, detailed discussion includes: identification of an individual component or a group of compounds; effect of a priori knowledge of the sample on the information gain of the result; importance of calibration methods and reference material and their net effect on the precision and accuracy of results; choice of the optimum analytical method, criteria of selection; quality control, external and internal quality assurance; chemicalhomogeneity testing. Particularly important in trace and multivariate analysis, the book also sheds light on the information content inherent in analytical instrumentation, contrasting it with the true information gains of the analysis. Essential to understanding the individual steps of analytical process, this distinction allows for better evaluation and optimization of each step, including calibration and signal processing. The book also assesses the information contribution of key chemometric methods, such as cluster analysis, pattern recognition, and factorial data analysis, useful in multivariate or multicomponent analysis. This discussion, in turn, provides insight into the true character of multivariate data analysis, revealing it as not simply a string of single-component analyses done simultaneously, but rather a fragile, potentially bias-ridden mechanism with unique interpretive potential of its own. Complete with tables, diagrams, and examples, Information Theory in Analytical Chemistry is a practical handbook of enhanced analytical techniques that can sharply improve the quality of data collection as well as a user's understanding of the significance of information theory in each step of the entire chemical analysis process.

For what is thought of as an essentially mechanical process, paper manufacture involves a large amount of chemistry. The Chemistry of Paper provides an overview of the process of making paper from a chemical perspective. It deals with both the chemistry of paper as a material and the chemistry of its production, setting out the main principles involved at every stage of the process. Early chapters provide a chemical definition of paper in the light of the many uses to which it is put. Subsequent chapters deal with the chemical processes involved in the production of paper: the delignification of the wood fibres performed at elevated temperature and pressure, the bleaching of the cellulose-rich pulp using environmentally-friendly systems, the formation of the pulp into sheets of fibres strengthened by extensive inter-fibre hydrogen bonding, and finally the coating of the sheets in a manner appropriate to their end use. Chemistry is involved at every stage of the process, including carbohydrate chemistry, the chemistry of inorganic pigments and organic resins, colloid and surface chemistry, as well as elements of environmental and analytical chemistry. The Chemistry of Paper provides an informative and entertaining overview of the chemical principles involved. It will be especially suitable for students and others who require an introduction to the chemistry of paper manufacture.

Trace Analysis is a highly practical book which deals with the science rather than the paperwork of quality assurance systems. Produced as part of the UK Valid Analytical Measurement (VAM) initiative, it provides the analyst with a systematic approach across the broad spectrum of trace analysis, offering practical advice and guidance on methodology and techniques. The book is structured to take the analyst step-by-step through the stages of any trace analysis. The approach is general, being broken down only into types of analyte. Additional chapters explain the application of groups of techniques to each analyte type. Each section contains references to published material which will allow the analyst to obtain further information on specific topics. Throughout the book, the analyst is reminded of pitfalls which lead to unreliable results. This new book therefore offers invaluable advice to analysts in all areas and at all levels, providing practical 'expert' advice on methodology. It will prove indispensable as a single, comprehensive bench guide for analysts in university, college and industrial laboratories.
Analytical chemists in industry are frequently faced with situations where a basic understanding of microbiology would be an advantage, for instance in the analysis of bacteria in food. Microbiology for the Analytical Chemist has been written specifically for analytical chemists who have little or no knowledge of microbiology, but might be required to interpret microbiological results. This book covers a wide range of microbiological situations in analysis. It deals with the question of establishing when a sample is contaminated, the problems of counting and identifying micro-organisms and establishing what effect they will have on the sample. The book examines the microbial contents of water and food. It also looks at the procedures for disinfecting and preservative testing. Traditional laboratory methods are discussed, and new rapid techniques are also considered. Microbiology for the Analytical Chemist is unusual in that it pulls together those aspects of microbiology which are of interest to analytical chemists and explains them at a basic level using practical situations as examples. This book will also be of interest to analytical chemists in academic or industrial laboratories, where there is no fund of microbiological experience to draw on.

From the global to the cellular level, oxidants have provided the chemical dynamic for reactions both harmful and benign. As varied in type as in effect, oxidants include the oxides of nitrogen, sulfur, and carbon - implicated in the generation of smog - as well as oxidants useful in hypoxic cell-specific anticancer drugs and the treatment of contaminated waters. The complex nature of oxidants as well as their pervasiveness in the environment have made them keenly interesting to scientists monitoring environmental hazards and human health. Environmental Oxidants is a broad-based, multidisciplinary study of the environmental chemistry and toxicology of oxidants as well as their widening role in pollution control. Featuring up-to-date research from internationally renowned scientists, the book sheds light on such critical topics as the evolution, production, distribution, and fate of oxidants in the atmosphere, hydrosphere, and biosphere; the influence of human activities on oxidative processes in the atmosphere; oxidative stress at the cellular, systemic, and ecosystem levels; and the use of oxidants to remediate polluted sites. Specific studies include photosynthetic oxygen evolution, oxidants in the unpolluted marine atmosphere, ozone formation in urban plumes, the impact of dynamics and transport on stratospheric ozone and other constituents, health effects and toxicology of ozone and nitrogen dioxide, and some hematological effects of oxidants. Reflecting current health concerns, the book also addresses such timely issues as oxidative stress and asbestos, the role of oxygen in lung toxicity induced by mineral fibers and particulates, as well as an alternative attainment criteria fora secondary federal standard for ozone. A selective and incisive look at the current state of research on oxidants, Environmental Oxidants provides environmental scientists and engineers with an informative, detailed discussion of just how and why oxidants have emerged as a key issue in human health and environmental integrity.

Incorporating the latest theoretical and experimental developments in the field over the past decade, Brainina and Neyman's Electroanalytical Stripping Methods focuses on the theory associated with the most progressive stripping electroanalytical methods (SEAMs) and their application to environmental monitoring and industry. Wherever appropriate, it highlights the main advantages of these methods, including their extremely low detection limit, the low cost of the instruments used, the possibility of speciation analysis, and their use in the investigation of solids as well as solutions. The combined work of two eminent researchers from the former Soviet Union, the book closes the previous information gap that existed between West and East and now makes accessible the most recent developments from Russia, including a different approach to initial electro-crystallization stages, the interconnection between voltammograms of binary metal systems and work functions, and the use of these phenomena in applied stripping voltammetry. Electroanalytical Stripping Methods also provides a critical assessment of current achievements in the field of electrode materials, and in the design of electrodes and electrochemical cells used in stripping methods. Here, the authors provide unique insight into the advantages of graphite electrodes - largely used in the East - over glassy carbon electrodes generally favored by the West. The book presents a number of other modern ideas, including the theory behind and the application of a new internal standard in stripping voltammetry...the catalysis of metals electrodeposition on the foreign substrate with adatoms...and the electrochemical transformation of solidsand adsorbates and their use in phase analysis and the investigation of the defect structure of solids. Electroanalytical Stripping Methods will prove to be an invaluable tool for professionals involved in environmental monitoring, helping them to develop and use trace analysis in evaluating drinking water, food, waste, and other solids and solutions and to apply stripping voltammetry to the analyses of chemicals. Researchers in the food, clinical, and pharmaceutical industries will similarly use the book to develop and apply SEAMs for trace analysis. Practitioners in the microelectronics industry will find useful information on solids that will help them improve the quality of catalyzers, films, special ceramics, and semiconductors. Finally, medical technicians will tap this resource for the insight it can provide in the electroanalysis of blood, urine, and other body fluids.
