The aim of this review is to summarize the difficulties likely to be encountered in the LC separation of basic solutes, which include the majority of pharmaceutical and also many biomedically important compounds. An answer to the problem of the separation of the cinchona alkaloids, fit for purpose, was obtained on the Hypersil column by adding the silanol blocking agent hexylamine to the mobile phase, which allowed the extra separation power of the smaller particle column to be exploited [3]. However, alternative solutions to the problem, which will be explored in this review, are more appropriate in particular circumstances there is no universal solution that is applicable in all cases. The present review will concentrate on the most recent developments in this subject for the past few years. Further background information can be found in earlier reviews by the present author [4,5] and by Snyder [6].

Each chapter in the Companion consists of an introduction. Learning Objectives, a Self-Test, Answers to Self-Test, Problems, Answers to Problems, and Expanded Solutions to Text Problems. The introduction sets the scene, places the chapter material in the context of what you have already learned, and reminds you of material you may need to review in order to understand what follows. The Learning Objectives are presented in the order that the information they encompass appears in Biochemistry. Key Words—important concepts or vocabulary—are italicized in the objectives. Self-Test questions, requiring primarily information recall, are followed by the answers to the questions. A Problems section, in which more complex skills are tested, is followed by answers to the problems. Finally, Expanded Solutions to end-of-chapter problems in the text are presented.

Try to work as many problems as you can. If you have trouble, two sources of help we suggest are your instructor and the Study Guide and Solutions Manual that accompanies this text. If you visit your instructors with your questions, you are likely to find that they are thrilled to be asked to help, and they may provide you with the insight you need to better understand a concept or problem. The study guide provides answers to the problems and explains how to solve them. It also provides you with review materials and additional problems that do not appear in the textbook. Problem solving is time-consuming, but it will pay off in an understanding of the subject...
