Books field and will be a welcome addition to the libraries of institutions active in food analysis. The book begins with a chapter summarizing HPLC theory, instrumentation, and separation media. Coverage of the material here is necessarily terse, and the chapter is useful primarily as a reference. Readers requiring more detailed explanations should investigate the many fulllength books available on these topics. The remainder of the book consists of chapters that each discuss one class of analyte. These analytes fall into two groups: compounds normally found in foods that have nutritional value (amino acids, peptides, proteins, lipids, carbohydrates, vitamins, and organic acids), and non-nutritive and/or potentially harmful compounds often not naturally present in foods (mycotoxins, antibiotic residues, additives, pesticide residues, bittering and phenolic compounds, organic bases, N-nitroso compounds, polynuclear aromatic hydrocarbons, and anions and cations). Although the chapters do not follow a fixed outline, each author typically reviews the chemistry of the analyte class, discusses the relationship of HPLC to other analytical techniques, describes the general methodology (columns, mobile phases, detection methods), and then describes specific HPLC methods. It would be impossible to describe each published method in detail; thus, many methods are summarized in tabular form. The critically important sample preparation aspect of food analysis has not been neglected, although individual authors have taken different approaches to the topic. In some chapters, sample preparation is broken out as a separate topic; in others, sample preparation methods are grouped with descriptions of chromatographic methods. The subject receives little attention in only a few chapters. A primary function of this type of work is to provide the reader with entry points into the literature. The book is commendably up to date in this regard. References are complete through the 1980s, and several references are from 1990 and 1991. Although there is a subject index, there is no author index. The apparent quick time to press does have a down side. The reader will find occasional editorial lapses: typographical errors, a structure drawing with pentavalent carbons, and one instance of a reference to a topic in a previous chapter that is not found in that location.

BOOKS RECEIVED Advances in Chemical Diagnosis and Treatment of Metabolic Disorders, Vol.1 Isamu Matsumoto, Ed. John Wiley & Sons 605 Third Ave. New York, NY 10016 1992, 165 pp., $60
This book contains the updated proceedings of the first two "Symposia on Clinical Diagnosis of Metabolic Disorders," held in Kanazawa, Japan, in 1989 and 1990. It is divided into five sections on lactic acidemia, organic acidemias, urea cycle disorder, drug-induced metabolic defects, and analytical techniques. Hyphenated techniques such as GC/MS and LC/MS as well as tandem MS and HPLC are used to determine specific metabolic disorders in the case studies presented. References are included through 1991, and the book contains subject and author indexes. Quality Assurance for Analytical Laboratories M. Parkany, Ed.

Analytical Chemistry, Vol. 66, No. 1, January 1, 1994
This text is Volume 55 in the Journal of Chromatography Library series and has been "completely revised." Chapter topics include an introduction to bioaffinity chromatography; the choice of affinity ligands; affinity ligand-sorbent bonding with consideration of steric accessibility and microenvironment effects of the matrix; solid matrix supports; ligand coupling procedures; characterization of supports and immobilized ligands; and sorption, elution, and nonspecific binding. The largest table in the book, at 188 pages, is contained in Chapter 9, and lists substances isolated by bioaffinity chromatography with the ligands and supports used for each and with appropriate references. References are current through 1990. Physical Methods of Chemistry, 2nd éd., Vol. 9B Bryant W. Rossiter and Roger C. Baetzold, Eds.
