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.

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-
