Self-paced courses on chromatography have been designed to stimulate a higher level of student attentivity and comprehension by requiring their interaction with the animations. A combination of mathematical programming with graphic output is used to explain relatively complex concepts in HPLC and GC. Chromatographic simulators show the results of changes on the chromatogram when instrumental parameters such as flow rate, particle size and gradient slope are varied. A non-linear tree structure is employed in the creation of simple question-and-answer “expert systems” to highlight a problem-solving approach to some practical chromatographic issues.
This presentation will be illustrated with examples of interactive animations and simulations, both numeric and graphic, as well as Q&A systems, selected from a series of GC and HPLC training programs.
