This is the first book that comprehensively and systematically describes the new technology of hydrophilic interaction liquid chromatography (HILIC). Hydrophilic interaction chromatography is a separation technique suitable for polar and hydrophilic compounds and orthogonal to reversed phase liquid chromatography. From small organic molecules to proteins, the text explores the many applications of HILIC in the analytical field. Winner of the President's Award for Excellence, the author explains how HILIC can significantly improve analytical throughput by shortening sample preparation procedure, which is one of the bottlenecks for drug discovery and development in the pharmaceutical industry.

The Comprehensive Guide to HILIC: Hydrophilic Interaction Chromatography, a 72-page book, illustrates how HILIC works and how separation scientists can improve their success in separating and quantifying polar compounds in a variety of sample matrices.

Discover how to use HILIC to analyze and better understand polar compounds An increasingly popular analytical method, hydrophilic interaction chromatography (HILIC) has the ability to retain and separate polar compounds that are often difficult to analyze by reversed-phase high-performance liquid chromatography (HPLC) or other analytical methods. Offering a comprehensive review, this book enables readers to develop a fundamental understanding of how HILIC works and then apply that knowledge to develop and implement a variety of practical applications. Hydrophilic Interaction Chromatography begins with discussions of HILIC retention mechanisms, stationary phases, and general method development. This sets the foundation for the book's extensive coverage of applications. The authors address unique separation challenges for bioanalytical, environmental, pharmaceutical, and biochemical applications. Moreover, there is a thorough discussion of HILIC in two-dimensional chromatography. With contributions from leading analytical scientists who have extensive experience in HILIC as well as HPLC, Hydrophilic Interaction Chromatography serves as a practical guide for researchers, featuring: Detailed examples of HILIC methods and development approaches Thorough explanations of retention mechanisms and the impact of stationary phase and mobile phase properties on separations Step-by-step guidance for developing efficient, sensitive, and robust HILIC methods References to the primary literature at the end of each chapter Hydrophilic Interaction Chromatography is written for scientists who use or develop analytical methods for the separation of polar compounds. In particular, these researchers will discover how HILIC can be used to analyze and better understand the composition of pharmaceutical, bioanalytical, biochemical, chemical, food, and environmental samples.

Hydrophilic interaction liquid chromatography (HILIC) has become in the last years a leading technique for the separation of small and large polar molecules. This chapter begins with a discussion about the most relevant characteristics of HILIC mode that makes it a complementary and, in some cases, alternative technique to the more traditional reversed- and normal-phase modes. Subsequently, the fundamentals of retention mechanisms in HILIC are revised in light of the most recent findings in the field. The chapter ends with an overview of the materials used as stationary and mobile phases in HILIC and of the applications of this analytical technique in different branches of science.
