Summary

A network model is proposed to describe the intraparticle porous structure of an SEC (size exclusion chromatography) column and solved using orthogonal collocation. Comparison of the retention and band broadening features with the conventional model of a parallel bundle of capillaries shows significant differences, which demonstrate the importance of including morphological characteristics into the model to account for the mass transfer restrictions.
