Abstract:

In order to keep up with the trend of informationization in teaching, a gas chromatographic simulation model based on the stochastic diffusion theory was established and the corresponding computer simulation software Stochastic Diffusion-Chroma was developed in this study. The simulations of diffusion and separation of mixed particles in both packed column and capillary column were presented. The application of stochastic diffusion theory in chromatography theoretical teaching and experimental teaching were explored. The simulation teaching based on stochastic diffusion theory changes the traditional teaching mode. It transforms the abstruse chromatographic dynamics into dynamic and intuitive description, stimulating students' interest in learning and improving teaching quality.
