Abstract. This paper
describes the design and development of an interactive, simulation-based
education software system for the exploration of key concepts in liquid
chromatography. Evaluation results of student use of the software will
be presented.
Software modules have been designed to supplement, but not replace, classroom
and laboratory learning about liquid chromatography, providing students
with theory, visual aids, and interactive simulations. Combined with animations
and narration, the modules complement the foundation on which chromatography
is taught in a general, analytical, or organic chemistry setting. Furthermore,
this software allows the student to interact with the illustrated chemistry
lessons, which is especially important in instances where the concepts
taught transcend typical classroom material.
This work serves to connect what one observes experimentally in a chromatography
experiment to changing parameters such as capacity factor, number of theoretical
plates, height equivalent of a theoretical plate, column length, resolution,
retention time, and selectivity factor. Simulated separations are portrayed
in an animated fashion as a chromatogram developing over time as a function
of one or more of these variables. Finally, the software has real sample,
mobile phase, column type, flow rate, and detection type options allowing
the selection and simulation of solving a realistic chromatography problem.
Hypothetical unknown mixtures can be separated and the sample components
identified after simulating the separation of known samples.
