In this course, you will learn how to develop methods and implement CE for the separation of biomolecules. The course begins with an extensive review describing the factors that influence the electrophoretic migration of molecules in fluid solution. A phenomenological approach is employed that enables the student to take home a thorough understanding of electrophoretic processes. The course is designed for analytical chemists and analytical biochemists and those in related fields who wish to implement capillary electrophoresis in their laboratories. While appropriate for novice users, the course will especially benefit experienced users who wish to broaden their background.

About The Lecturer
Dr. Robert Weinberger
Since 1991, Dr. Weinberger has been a consultant specializing in the field of High Performance Capillary Electrophoresis and related technologies. He is President of CE Technologies, Inc., a consulting firm specializing in contract research in HPCE. He taught the American Chemical Society Short Course entitled "Capillary Electrophoresis of Biomolecules" for 25 years and is the author of the textbook “Practical Capillary Electrophoresis”.
He has written some 100 Magazine articles for American Laboratory and is the author of over 50 technical publications, book chapters and patents in the fields of electrophoresis and liquid chromatography. He served as an expert witness in capillary electrophoresis patent litigation and provided expert opinions concerning the purity of potentially contaminated heparin samples. Food and drug contamination, dietary supplements and glycoprotein separations are recent areas of investigation.
