Abstract: Aim An imitative system of adsorption chromatography was established and applied.Methods A multi-compartment desorption theory model in adsorption-chromatography was put for-ward, some formulae were deduced and a computer program was compiled. Results The model could imitate the best curve of adsorption-chromatography according to the experimental re-quirement and reveal the relationship between the time and the concentration of a certain com-partment. Conclusion The system could bring about a better isolation effect than the tradi-tional method of two-compartment linear desorption.
