Separation methods are crucial to chemistry and to the cognate fields that rely on chemistry to introduce their students to a range of analytical methods. Increasingly, separations are being taught in introductory chemistry courses, and a combination of hands-on and virtual approaches to the topic are a useful way to introduce both the general principles that are behind most separations methods and the specifics of particular techniques. Principles of Gel Permeation Chromatography is an interactive Flash animation designed to help your students learn the basic principles of gel permeation chromatography from the convenience of any computer with an Internet connection. The animation makes use of a mixture of the actual setup for a gel permeation separation and simulations of the physico-chemical processes that result in separation. Students can explore the software individually or in small groups, either in free exploration or as part of an assigned exercise. The software can also be used effectively as a visual aid for large group lectures and would also make a useful pre-laboratory exercise.
