Reproducible results require Even with today's sophisticated analytical instrumentation, your results are only as good as your sample preparation. At we know the importance of homogenous samples for ensuring the accuracy and consistency of analytical results. After all, spectroscopy is our business. Over the last thirty years we've invented ingenious devices for turning non-homogeneous materials into finely ground, homogeneous powders and compact pellets. And we continue to provide spectrascopists with the best equipment on the market for grinding, pressing, and holding samples. Our extensive line of sample-preparation equipment includes • mills, mixers, and grinding containers • manual and motorized presses and dies • disposable sample holders and cells for XRF Shouldn't you be dealing with the spectroscopy specialists at Call us today at (800-522-7739], We'll send you a Jjfree catalog that describes our J^^U^ complete line of laboratory ^ w equipment.

Books Overall, the strength of this book lies in the wealth of practical informa tion presented, as well as the large number of examples of and references to the use of GC capillary columns. Those interested in these (largely ap plied) matters will find the book to be valuable; certainly beyond doubt is that compared to other recent of ferings that purport to deal with the same subject matter, this work excels. Unfortunately, however, those who are interested in a modern treatment of the fundamental aspects of open tubu lar column gas chromatography will be disappointed.

Reviewed by Robert Petty, Marine Science Institute, University of Cali fornia, Santa Barbara, Calif. 93106 The purpose of this book is to update and expand the material cov ered in the first edition, which was published in 1976 and "was quickly accepted by marine scientists as a reli able source of information on analyti cal procedures specifically developed for the use with seawater" (from the preface). Its main emphasis is on pro viding detailed methods for the deter mination of specific substances and properties of seawater. A general dis cussion and specific information on seawater sampling and sample storage and a chapter on automated chemical analysis are also included. Although not intended as compre hensive reviews, each chapter is a rea sonably thorough presentation of a particular topic. The choice of topics, however, has resulted in a wide varia tion in chapter length and complexity. For instance, chapter 6 is a four-page description of the titrimetric determi nation of thiosulfate, whereas chapter 9 is 64 pages long and covers the de termination of nutrients by presenting one section on phosphorus, one on sili ca, and five sections on various forms of nitrogen. Most of the substances covered are specific compounds, ions, or elements. The extensive chapter on organic constituents, however, ad dresses mainly classes of substances, including petroleum residues, organochlorines, phenolics, amino acids, and carbohydrates. Determination of indi vidual components within these groups is generally made possible by chromatographic techniques. Typically included for each analyti cal species or property are an intro-
