able balance of theory and practices; thus, the book should appeal to both the theorist and the practicing chemist. The analytical chemist should not buy the book with the hope of finding detailed analytical methods. However, after mastering the principles provided by the authors, the analytical chemist should be able to devise fractionation schemes for the separation of polymeric materials on the basis of molecular weight or comonomer composition.

ULTRAPURE chemicals
When you simply can't tolerate impurities or uncertainties in your reagents Over 100 of the purest reagents and chemicals available anywhere in the world. Every product is accompanied by a detailed Certificate of Analysis of the actual lot supplied. In terms of spectrochemically detectable impurities, ULTREX products are typically 99.995% to 99.99995% pure. And the extremely low content of all impurities (often at the parts per billion level) satisfies the most rigid use requirements. Whenever your requirements for purity and product definition are stringent, ULTREX ultrapures can indeed insure against loss of time, effort, and other expenses. Consider ULTREX when you just can't afford to gamble with impurities or uncertainties.

Some of the important applications of the isoelectric focusing technique are reviewed by 11 authorities in the field. A total of 10 chapters deal with the use of the isoelectric focusing technique for the separation and characterization of different types of proteins such as hemoglobin, allergens, muscle proteins, nuclear nonhistine proteins and seed proteins present in various biological media. The book emphasizes recent advances in knowledge rather than methodology aspects, except when special procedures are reviewed. High Performance Mass Spectrometry: Chemical Applications (ACS Symposium Series, Vol. 70). Michael L. Gross, Ed. ix + 358 pages. American Chemical Society, 1155 Sixteenth St., N.W., Washington, D.C. 20036. 1978. $28
A symposium on mass spectrometry was hosted by the University of Nebraska, Lincoln, Neb., November 3-5, 1976. The objective of the forum was to review the current state of knowledge, with particular emphasis on structure, property, and energy surface determinations of gas-phase ions, and applications of high-performance mass spectrometry to trace analyses of biological and environmental samples. The 18 papers presented at that symposium were updated during 1977 and are collected in this volume. Although the papers in general represent original contributions and therefore emphasize the research carried out at the authors' own laboratories, each chapter also contains a review of the fundamental principles necessary to understand the research. The volume is divided into two sections. The first in-

Marine Chemistry in the Coastal Environment ACS Symposium Series No. 18 Thomas M. Church, Editor A special symposium sponsored by the Middle Atlantic Region of the American Chemical Society.
Now available—a comprehensive volume containing the most recent advances in this new and increasingly important field.
The collection represents an indispens able source of information for every marine scientist. Emphasis is not merely on describing coastal problems but on showing the potential in applying the tools of modern oceanography and chemistry to solve these problems.
Forty-one chapters cover six major areas: physical, organic, and tracer marine chemistry; estuarine geochemistry; hydrocarbons and metals in the estua rine environment; ocean disposal forum; applications and resources in marine chemistry; and organic and biological marine chemistry.

eludes five chapters describing meth ods for acquiring metastable ion data that relate to stable and low-energy decomposition ions and the applica tion of these methods for determining ion structures, properties, and poten tial energy surfaces. The second sec tion is a survey of analytical applica tions that can be explored with highperformance mass spectrometry. Gen eral applications on qualitative and quantitative analyses with direct inlet and GC methods of sample introduc tion are described. The book is repro duced from author-furnished type written text. Instrumental Organic Elemental Analy sis. R. Belcher, Ed. xi + 299 pages. A c ademic Press Inc., Ltd., 2 4 - 2 8 Oval Rd., London NW1 7DX, England. 1977. $27.35
This monograph on methods of ele mental organic analysis based on in strumentation is contributed by six analytical chemists who have had first-hand experience with a variety of commercially available automated an alyzers. In chapter 1, M. R. Cottrell and F. H. Cottrell introduce the Perkin-Elmer Model 240, widely used for the determination of carbon, hydro gen, and nitrogen. The discussion in cludes all aspects of the analyzer from the principles behind .the automation and the basic chemistries involved, to the evaluation of analytical data and proper maintenance of the instru ment. Chapter 2 by the same authors describes the modification of the Perkin-Elmer Model 240 for analysis of oxygen and sulfur. In Chapter 3, C. J. Howarth describes the Carlo Erba an alyzer, widely used for the determina tion of carbon, hydrogen, nitrogen, and oxygen. This chapter also pro vides an in-depth discussion of all as pects of the instrument. Chapter 4 on the determination of organic carbon in water is by R. Kubler. It discusses the principles of operation, main applica tions, and characteristics of nine auto mated analyzers used for the determi nation of total organic carbon content. Chapter 5 by P. I. Brewer is devoted to the determination of nitrogen by the Merz modification of the Dumas method. The longest (131 pages) and the final chapter on microcoulometric methods for the determination of sul fur, chlorine, nitrogen, and individual compounds is written by F.C.A. Killer. Although a variety of commercial ana lyzers designed for specific analyses are mentioned, the emphasis of this chapter is on the review of the poten tial of microcoulometry as a method of elemental analysis.

This book is intended for analysts working in industrial quality control laboratories and for those dealing with steroid hormones and their intermedi ates in the pharmaceutical industry. As such, the coverage does not include methods of the biological-clinical analyses of steroids in biological fluids, except in those cases where a method is applicable to all cases. The first three chapters discuss the basic knowledge of steroids (chemical, phar macological, and analytical), which is essential for analysts dealing with these compounds. Chapters 4-7 review various analytical techniques used for qualitative and quantitative analyses of steroid compounds. The discussion of the quantitative analysis of formu lations in Chapter 8 is presented in the traditional manner based on their pharmacological classification. Final ly, Chapter 9 provides a brief survey of the analysis of the most important raw materials of steroid semisyntheses.

Following the extensive treatment of infrared and Raman spectroscopy in three parts in its first volume, this new series on practical spectroscopy covers x-ray spectrometry in Volume 2. As in the first volume the book is multiauthored (18) and reproduced from typewritten text. The first nine chapters on methods and instruments provide an introduction to the physi cal concepts necessary to understand the rest of the book. The chapters are entitled: wavelength dispersion, ener gy dispersion, data interpretation, precision and accuracy, electron exci tation, proton and alpha excitation, electron probe microanalyzers, bond ing and electron spectroscopy, and se lection and safe operation. The re maining seven chapters describe ap plications of x-ray methods in varied areas such as the general service labo ratory, metals and alloys, geology, mining and ore processing, microanal ysis and trace analysis, museum objects, and x-ray astronomy and other exotic applications.
