tems and peptldes and an equally well written account of then LC Overall this 1s a useful reference book and most of the chapters would be of mterest to analysts m industries other than the pharmaceutlcal mdustry R P Munden A Lee Snuth (Ed ), The Analytical Chemlstty of Sdtcones, Wiley, New York, 1991 (ISBN 0-47151624-4) xxu + 551 pp Price &9735 This book 1s wrltten by a team of experts from Dow Corning under the supervlslon of A Lee Smith It gives a wealth of mformatlon about all types of sdlcones which form a very interesting class of compounds with many attractive features The application of silicones 1s rather widespread as reflected m the various chapters Silicon belongs to the group IV elements Just hke carbon and, m fact, there are some slmllantles between s&con compounds and orgamc compounds However, as pointed out m the mtroductory part, large differences also exist The book consists of three parts After a short mtroductlon to slhcones m general, the second part deals with what 1s called “the problem-onented approach” It consists of 5 chapters the analytical chemistry of organo-silicon materials (Chap 21, the analysis of polymers, mixtures and composltlons (Chap 31, trace analysis mvolvmg slhcones (Chap 4), the analysis of surfaces (Chap 5) and personal care apphcatlons (Chap 6) The third part gives a full account of the basic techmques used m the analysis of silicones Here the various chemical and instrumental techniques are dlscussed m depth m 9 chapters The book 1s well-written and easy to read It gives a good impression of the posslbdltles and dlfflcultles to be expected when sillcone compounds have to be analyzed Although It 1s a multi-author book, the style 1s consistent throughout, probably because the edltor has mamtarned a strmgent scheme m the set-up of each chapter Especially the idea of starting the book with exposltlons of the mam fields of apphcatlons and the related analytical problems seems attractive It has the advantage that each chapter can be
read separately, but it has the drawback of many repetitive remarks on subjects like sampling, etc The hst of references IS up-to-date and covers pubhcatlons until the end of 1989 and the begmning of 1990 In summary, I can strongly recommend the book for those who are Interested m slhcone chemistry and the analytical chemistry mvolved Wlllem E van der Linden B W Rosslter and J F Hamilton (Eds 1, Physzcal Methods of Chemrstry 2nd edn, Volume IV Mlcroscopy, Wiley-Interscience, New York, 1991 (ISBN 0-471-08026-S) XIV+ 539 pp Price ilO9 00 This volume deals with various aspects of transmission electron microscopy and diffraction, aimed to reflect the rapid and significant advances m the field m the last decade or so It IS not self-contained so that Volume V Determmatton of Structural Features of Ctystallme and Amorphous Sol&s 1s an essential companion vol-
