Laboratory Experiments in Trace Environmental Quantitative Analysis


Book Description

Laboratory Experiments in Trace Environmental Quantitative Analysis is a collection of student-tested experiments that introduce important principles that underlie various laboratory techniques in the field of trace environmental organics and inorganics quantitative analysis. It crosses the more traditional academic disciplines of environmental science and analytical chemistry. The text is organized to begin with minimally rigorous session/experiments and increase in rigor as each session/experiment unfolds. Each experiment features learning objectives, expected student outcomes, and suggestions for further study. Additional features include: Students are introduced to the principles and laboratory practice of instrumental analysis (determinative techniques) that are clearly presented. Students are carefully taken through various ways to prepare samples for trace quantitative analysis (sample prep techniques). Safety warnings are listed within each experiment. Students are introduced to all three types of instrument calibration: external, internal and standard addition. Instructors who are responsible for laboratory courses in analytical chemistry with potential application to environmental sample matrices will find this textbook of value. Graduate programs in environmental science and engineering will also greatly benefit from the content.

Trace Environmental Quantitative Analysis


Book Description

A thorough and timely update, this new edition presents principles, techniques, and applications in this sub-discipline of analytical chemistry for quantifying traces of potentially toxic organic and inorganic chemical substances found in air, soil, fish, and water, as well as serum, plasma, urine, and other body fluids. The author addresses regulatory aspects, calibration, verification, and the statistical treatment of analytical data including instrument detection limits; quality assurance/quality control; sampling and sample preparation; and techniques that are used to quantify trace concentrations of organic and inorganic chemical substances. Key Features: Fundamental principles are introduced for the more significant experimental approaches to sample preparation Principles of instrumental analysis (determinative techniques) for trace organics and trace inorganics analysis An introduction to the statistical treatment of trace analytical data How to calculate instrument detection limits based on weighted least squares confidence band calibration statistics Includes an updated series of student-tested experiments




Trace Environmental Quantitative Analysis


Book Description

This study offers insight into the principles of trace environmental quantitative analysis (TEQA), focusing on data reduction and interpretation, sample preparation and instrumental analysis from a wide range of matrices, including sludge, sediment, oil and air, as well as ground, waste and surface water. It draws on the author's own research with metal chelate solid-phase extraction.
















Trace Environmental Quantitative Analysis


Book Description

Trace Environmental Quantitative Analysis: Principles, Techniques, and Applications, Second Edition offers clear and relevant explanations of the principles and practice of selected analytical instrumentation involved in trace environmental quantitative analysis (TEQA). The author updates each chapter to reflect the latest improvements in TEQA that have resulted in greater levels of sensitivity. The book begins with an overview of regulatory and EPA methods, followed by quantitative data reduction and interpretation of analytical results, sample preparation, and analytical instrumentation. Among the more than two-dozen new topics are the underlying principles of GC-MS, GC-MS-MS, LC-MS, and ICP-MS, column chromatographic cleanup, gel permeation chromatography, applications to biological sample matrices, and matrix solid-phase dispersion. The chapter on sample preparation now includes more alternatives to liquid-liquid extraction, highlighting Solid Phase Microextraction (SPME), and Stir Bar Sorptive Extraction (SBSE). The final chapter contains laboratory-tested experiments to practice the techniques appearing in the text. Appendices include a convenient glossary, applications to drinking water, computer programs for TEQA, instrument designs, and useful Internet links for practicing environmental analytical chemists. Featuring personal insight into the theory and practice of trace analysis from a bench analytical chemist, the second edition of Trace Environmental Quantitative Analysis takes readers from the fundamental principles to state-of-the-art methods of TEQA currently used in leading laboratories.
