Development of chromatography — a review

Stationary phase SoUd sorbent Liquid sorbent 

When describing the chromatographic process in terms of mathematics it is necessary to define a suitable (sufficiently realistic and yet mathematically tractable) model of chromatography. From the point of view of theoretical considerations the following models are of interest [10], 

In this way four combined models of chromatography may be postulated A, ideal linear B, non-ideal linear C, ideal non-linear and D, non-ideal non-linear. Whereas the models B and D are real, the models A and C are apparently hypothetical. In spite of this even the latter two models are very useful from the theoretical point of view.
