A classroom activity has been developed that allows students to perform chromatographic separations in the classroom through active participation. Using this classroom simulation, students develop a set of rules used to investigate the effect of flow rate, column dimension, particle size, and mobile/stationary phase affinity on chromatographic separations. While performing the simulation, the concepts of longitudinal and eddy diffusion are dramatically illustrated. Students are not only active participants throughout the entire separation; they also directly observe an evolving separation. The simulation allows students to set initial parameters, watch, and directly participate in isocratic and gradient separations occurring in real time.
