Lloyd R. Snyder Joseph J. Kirkland Joseph L. First published: Print ISBN: About this book This revision brings the reader completely up to date on the evolving methods associated with increasingly more complex sample types analyzed using high-performance liquid chromatography, or HPLC.

The book also incorporates updated discussions of many of the fundamental components of HPLC systems and practical issues associated with the use of this analytical method. This edition includes new or expanded treatments of sample preparation, computer assisted method development, as well as biochemical samples, and chiral separations.

Its goal, as summarized in the last chapter, is to enable the reader to develop a useful, practical, and working method of separation for a given sample, without at times even knowing its composition. The book is very readable.

The reader is led through the basic principles of separation development, basics of mobile phase effects on separation resolution vs. Throughout the book there are tables of steps for ensuring success in each of the components leading to a final, successful and reproducible separation.

For instance, there are tables of steps for ensuring good column lifetimes and performance, for a systematic approach to obtaining an HPLC separation, for preferred HPLC methods and columns for different samples, for additional separation variables to change band spacing in HPLC, for controlling band spacing in reversed-phase HPLC, etc. The tables and figures are clearly conceived and produced, and are designed to aid the reader in using all the various parts of an HPLC system to develop a suitable and practical separation method.

The central four chapters , dealing with approaches to systematic method development, difficult for a user with limited GC-MS experience to obtain a rapid review of GC-MS principles. As GC-MS instruments proliferate in use, this module will undoubtedly find a niche in many laboratories as a valuable training aid.

They contain most of the practical hints and steps for method development, and deal with virtually all the major components available to the chromatographer using HPLC.

Chapter eight deals with computer-assisted method development, and describes many of the more important and popular software programs available today for system HPLC optimization, resolution optimization, gradient development, peak capacity maximization, data analysis, instrument control, and so forth.

This chapter is clear, lucid, concise and describes how the software works, how it can be optimized, how it can be routinely employed, and what it cannot yet do. The authors have emphasized their own DRYLAB software, which is commercially available, and though there are clear efforts not to be prejudiced, some bias was probably unavoidable.

Other software programs are described, but they seem to me to get less emphasis. Simplex is discussed, but not more advanced forms of system optimization, such as multiplex or optiplex. The last chapter nine alone is worth the price of the book. It summarizes method development procedures in almost cookbook or roadmap fashion: These flow-charts are really practical, and together with the descriptions, are easy to follow to develop an optimized method in reversedor ion-pair phase, normal-phase, HPLC.

This chapter teaches the reader how to develop a particular separation, without even knowing the sample constituents. One problem I had with the book is that it does not really assume that the analyst knows his sample makeup or for which analyte s he is developing a method. It is assumed that the analyst just wishes to resolve all components in his particular sample, which may or may not be the case.

If we have a complex sample, but only need to analyze for one component, we obviously do not need to resolve all constituents to baseline. For one, the authors, perhaps expectedly, have referenced much of their own work. Indeed, in any given reference list for a specific chapter, usually half of the items are from one or more of the authors.

Granted that they have published a great deal in all areas of HPLC, especially in optimization, methods selection and development, packings, and so forth, but it would have been nice to see other work mentioned more often. The references are very up-todate, with very few before There is no discussion of method validation, nor how to determine when separation has been optimum reached, what criteria should be used and how reproducibility, accuracy, precision, and validation can be demonstrated.

Is it only baseline resolution of all components in the shortest time possible, minimum peak asymmetry numbers, maximum peak capacity, shortest gradient times, what else? Usually, we develop an overall method of identification and quantitation for an analyte in the sample, not just its best possible separation.

An HPLC separation is but a part of the final method, and ultimately it will be used along with analyte identification methods, quantitation, sample preparation and work-up, analyte extraction and pre-concentration, data acquisition and manipulation, etc.

How do we then validate that method, if at all? How do we validate the final, presumably optimized HPLC separation? Few of us develop separations alone, whereas this book really discusses HPLC separations development, not final analytical methods involving HPLC separations. Finally, the book assumes that virtually any mixture of compounds can be separated via normal-phase, reversed-phase, or ion-pairing techniques, columns, and mobile phases.

It seldom addresses the question of sample mixtures that contain mixed analytes, perhaps both charged and uncharged solutes, or those of widely differing molecular weights, or those with both anions and cations, etc. It treats sample mixtures as simple components of 16 polycyclic aromatic hydrocarbons, or 4 basic amine drugs, or odd synthetic organic compounds, or 8 peptides, or x-substituted aromatics unspecified structures , etc.

Reality is more complex.

What do we really have to know about the sample components if we wish to separate all of them from one another? Multidimensional chromatography is mentioned, all too briefly, given what it can do for very complex samples.

This book is to be recommended to all those who use or will use HPLC for methods development.
