The complexity of the HPLC method allows on one side a wide variety of usage. On the other side it is also a source of possible errors. This book does not only list them, but illustrate them with concrete examples. The topics were presented in a clearly arranged style: a brief text with a corresponding figure. Chemists and laboratory assistants get here numerous hints how correct and reliable results could be transposed in daily laboratory work.

How can I use my HPLC/UHPLC equipment in an optimal way, where are the limitations of the technique? These questions are discussed in detail in the sequel of the successful "HPLC Expert" in twelve chapters written by experts in the respective fields. The topics encompass - complementary to the first volume - typical HPLC users' problems and questions such as gradient optimization and hyphenated techniques (LC-MS). An important key aspect of the book is UHPLC: For which analytical problem is it essential, what should be considered? Besides presentation of latest developments directly from the main manufacturers, also UHPLC users and independent service engineers impart their knowledge. Consistent with the target groups, the level is advanced, but the emphasis is on practical applications.

General Editor: A.D. Smith High Performance Liquid Chromatography in Neuroscience Research Edited by R. Bruce Holman, Alan J. Cross and Michael H. Joseph This volume in the Handbook Series begins with a succinct introduction to the principles of High Performance Liquid Chromatography (HPLC) and to the principles of methods development for neuroscience application. The primary emphasis of the book is on detailed and functional description of methods for a wide range of specific groups of neurochemicals, with particular emphasis on the analysis of neurotransmitters and related compounds. The final chapter reviews the application of HPLC to the analysis of central nervous system (CNS)-active drugs. Each chapter is written by experts in their fields. As well as providing a brief overview of the choice of methodologies, they focus on specific methods to provide the maximum amount of practical information based on personal experience, illustrated by material from the analysis of real biological samples.
