Many laboratories are engaged in research on the development of new fluids for use as refrigerants to replace the fully halogenated materials that are believed to contribute to atmospheric ozone depletion. An integral part of this effort is the chemical analysis of new fluids that are synthesized, prepared, and tested. This comprehensive book, which is divided into two parts, fills an important need in this vital chemical analysis protocol. The first part reviews the major chemical analysis methods that have been developed and used at NIST and in other laboratories. This review covers spectroscopic, chromatographic, and "wet" analytical methods, with treatment divided by qualitative identification, qualitative determinations, and chemical reaction screening. The second part contains a compilation of analytical information of the new fluids and their products. Physical properties, mass spectra, infrared spectra, ultraviolet spectra, nuclear magnetic resonance spectra, and gas chromatographic retention data are provided for each fluid or product.
In this volume, we have collected a series of reviews that cover both experimental and theoretical work geared toward the more exact requirements of current SFE applications. While we have artificially divided the volume into experimental and theoretical sections, natural overlaps will be apparent. Many of the papers on experimental and theoretical sections, natural overlaps will be apparent. Many of the papers on experimental technique contain discussions on equation of state correlations. Indeed, a good deal of the experimental work is intimately tied to a mathematical description of fluid mixtures. The theoretical section presents reviews that cover the modern theory of critical phenomena, methods to correlate near critical experimental results and approaches to understanding the behavior of near critical fluids from microscopic theory. It is hoped that the scope of these reviews will provide the reader with the basis to further develop our understanding of the behavior of supercritical fluids.
Researchers in chemistry, chemical engineering, pharmaceutical science, forensics, and environmental science make routine use of chemical analysis, but the information these researchers need is often scattered in different sources and difficult to access. The CRC Handbook of Basic Tables for Chemical Analysis: Data-Driven Methods and Interpretation, Fourth Edition is a one-stop reference that presents updated data in a handy format specifically designed for use when reaching a decision point in designing an analysis or interpreting results. This new edition offers expanded coverage of calibration and uncertainty, and continues to include the critical information scientists rely on to perform accurate analysis. Enhancements to the Fourth Edition: Compiles a huge array of useful and important data into a single, convenient source Explanatory text provides context for data and guidelines on applications Coalesces information from several different fields Provides information on the most useful "wet" chemistry methods as well as instrumental techniques, with an expanded discussion of laboratory safety Contains information of historical importance necessary to interpret the literature and understand current methodology. Unmatched in its coverage of the range of information scientists need in the lab, this resource will be referred to again and again by practitioners who need quick, easy access to the data that forms the basis for experimentation and analysis.
Analytical instrumentation is crucial to research in molecular biology, medicine, geology, food science, materials science, forensics, and many other fields. Undergraduate Instrumental Analysis, 8th Edition, provides the reader with an understanding of all major instrumental analyses, and is unique in that it starts with the fundamental principles, and then develops the level of sophistication that is needed to make each method a workable tool for the student. Each chapter includes a discussion of the fundamental principles underlying each technique, detailed descriptions of the instrumentation, and a large number of applications. Each chapter includes an updated bibliography and problems, and most chapters have suggested experiments appropriate to the technique. This edition has been completely updated, revised, and expanded. The order of presentation has been changed from the 7th edition in that after the introduction to spectroscopy, UV-Vis is discussed. This order is more in keeping with the preference of most instructors. Naturally, once the fundamentals are introduced, instructors are free to change the order of presentation. Mathematics beyond algebra is kept to a minimum, but for the interested student, in this edition we provide an expanded discussion of measurement uncertainty that uses elementary calculus (although a formula approach can be used with no loss of context). Unique among all instrumental analysis texts we explicitly discuss safety, up front in Chapter 2. The presentation intentionally avoids a finger-wagging, thou-shalt-not approach in favor of a how-to discussion of good laboratory and industrial practice. It is focused on hazards (and remedies) that might be encountered in the use of instrumentation. Among the new topics introduced in this edition are: • Photoacoustic spectroscopy. • Cryogenic NMR probes and actively shielded magnets. • The nature of mixtures (in the context of separations). • Troubleshooting and leaks in high vacuum systems such as mass spectrometers. • Instrumentation laboratory safety. • Standard reference materials and standard reference data. In addition, the authors have included many instrument manufacturer’s websites, which contain extensive resources. We have also included many government websites and a discussion of resources available from National Measurement Laboratories in all industrialized countries. Students are introduced to standard methods and protocols developed by regulatory agencies and consensus standards organizations in this context as well.
From forensics and security to pharmaceuticals and environmental applications, spectroscopic detection is one of the most cost-effective methods for identifying chemical compounds in a wide range of disciplines. For spectroscopic information, correlation charts are far more easily used than tables, especially for scientists and students whose own a
