Mathematical modeling of the peak in liquid chromatography

A program for the numerical solution of the transport differential equation describing the behaviour of a peak on a chromatographic column for an arbitrary shape of the equilibrium isotherm and an arbitrary amount injected for one- and two-component systems is presented. For one component, the influ...

Description
Summary:A program for the numerical solution of the transport differential equation describing the behaviour of a peak on a chromatographic column for an arbitrary shape of the equilibrium isotherm and an arbitrary amount injected for one- and two-component systems is presented. For one component, the influence of the axial dispersion coefficient, the separation coefficient, the curvature of the equilibrium isotherm and the apparatus function of the detector were examined. For a two-component system, the column overloading for pairs of components with various mutual influences was studied.
