In the Classroom
Simulating Chromatographic Separations in the Classroom
Charles A. Smith and F. Warren Villaescusa
Department of Chemistry, Our Lady of the Lake University, San Antonio, TX 78207

Vol. 80 No. 9

Abstract
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.

Chemistry Teacher Connection

The "Chemistry Teacher Connection" (CTC) is especially for high school chemistry teachers. For only $40/year, it offers an online-only subscription to CLIC along with membership in the Division of Chemical Education, normally $65/year. CTC subscribers receive access to all articles and supplements from 1996 through the current issue.
