Gel permeation chromatography Chromatographic Science Series Vol. 19 Liquid Chromatography of Polymers and Related Materials III edited byJack Gates, Marcel Dekker, Inc., 1981. SIG 112 (viii + 299 pages) ISBN 0 8247 I514 4 This book contains 14 papers presented at an International Symposium held at Framingham, Massachusetts in October 1980. It is volume 19 in the Chromatographic Science Series published by Marcel Dekker. The proceedings of the two previous Symposia were included in volumes 8 (1977) and 13 (1980) of the same series. Despite the title, this volume contains only two papers concerned with conventional liquid chromatography. Hadad describes the characterization of printed circuit board materials by liquid chromatography, and Kuo and co-workers show how oligomers and small molecules in coating systems be characterized by liquid may chromatography and gel permeation chromatography (GPC). Most of the book reports work on size-exclusion separations by GPC. Two decades ago John C. Moore developed macroporous crosslinked polystyrene gels for the chromatographic fractionation of
polymers and proposed the term ‘gel-permeation chromatography’. His 2 contributions to this book present interesting views on the separation and band-broadening processes occurring in GPC columns. The remaining papers cover a wide range of topics, but 2 main themes emerge. Five papers are concerned with developments in the technique ofGPC. High performance systems for high speed separations with very efficient columns have attracted much attention in recent years. Hellman and Johnson discuss the effectiveness of the internal-standard method in data processing, and Chow and Long describe how coiled microcolumns may be employed for fast separations. The possibility of secondary separation mechanisms perturbing retention due to size-exclusion should always be considered in GPC. Monrabel describes how solute retention is influenced by modieing the silica surface by covalent grafting of polystyrene and Taylor and co-workers show how the retention of polysulphone depends on the choice of the packing-solvent system. On-line molecular weight detection in GPC permits the direct characterization of
Stimulating steroids! Analytical Chemistry Symposia Series, Vol. 10, Advances in Steroid Analysis, edited by S. GZg, Elsevier Scientific Publishing Co., 1982. lJS$104.75/Djl 225.00 (xi + 552 pages) ISBN 0 444 99711 3 This book contains the text of the plenary lectures, contributed papers, and posters presented at the Symposium on the Analysis of Steroids, held in Eger, Hungary, 20-22 May, 1981. American publishers are now reluctant to bring out proceedings of symposia, mainly because the production delay is so long that the material is partly obsolete at the time of publication. One of Gijriig’s important accomplishments is the relatively prompt publication of this international symposium, which obviously could only be attended by a fraction of the multitude of scientists interested in steroid analysis. The book, produced by direct photoreproduction of the typewritten manuscripts, contains a wealth of
papers on all the important groups of steroids: sterols, vitamin D, bile acids, steroid hormones, and many plant steroids, including the cardiac glycosides. The currently most widelyused methods, chromatography and immunoassays, occupy most of the space, but spectroscopic and other analytical methods are not forgotten. Among the plenary lectures, particular mention must be made of the expert reviews on estrogen analysis by Adlercreutz et al.; steroid analysis in the pharmaceutical industry by Gariig * steroid immunoassays by Itl, ff,Ut&e ; the combination of gas chromatography and mass spectrometry by Brooks et al.; and the combination of isotope dilution and mass spectrometry by Bjijrkhem. A paper on the relationship between chemical structure and relative mobility in TLC by Hais and Vodickov& likewise, has permanent value. Obviously, there are also some papers among the 69 articles presented at the symposium that are of more
the eluting polymer without the need for calibration with reference materials. The results from detection by low-angle laser light scattering reported by Rooney and Ver Strate emphasize that high molecular weight polymers separating at fast flow rates with columns containing microparticulate packings may be subjected to mechanical degradation. The remaining 5 papers describe the application of GPC to various separation problems. These are branched block copolymers (Ambler), polyphosphazenes (Hagnauer and Koulouris), oligomers (Heitz), polyolefin characterization (Westerand the determination of man), polyethylene melt-index (Dark). This book contains a wide range of topics and should be purchased by libraries serving laboratories involved with the analytical chemistry of polymers. Although workers performing size exclusion separations will be interested in several papers describing significant advances, this range of topics is likely to deter polymer analysts from buying personal copies.

temporary interest, but their caliber is quite generally high. I found the entire book very stimulating reading and recommend it to those of my colleagues who, like myself, missed the opportunity of meeting some of the outstanding steroid analysts from other countries, mainly from Eastern Europe.

BOOK PREVIEWS These will discuss books which are due to appear in the near future, giving an approximate date of publication. They will assess only the scientific content of the book, and will not comment on the standard of production or price.
