An introductory site about chromatography designed for freshman course that does not go into great depth. However, the simulation of paper chromatography is worth exploring with students as it illustrates that the separation of compounds relies on the difference in the solutes affinities for the mobile phase relative to the stationary phase. Because of its apparent simplicity, this simulation has significant pedagogical potential and could be used in a variety of ways in class to explore the factors governing chromatographic separations.
