DISPERSION IN CHROMATOGRAPHY - A VISUAL R EPRESENTATION AT THE MOLECULAR-LEVEL

Processes occurring as a result of numerous random molecular events su ch as molecular diffusion and chemical reactions or equilibrium ms are well simulated using molecular automata. Neither differential nor sta tistical equations ave required: the macroscopic characteristics of a set of molecules are recreated from the microscopic behaviour of these molecules. Such a method has been applied to elution chromatography i ncluding diffusion and adsorption-desorption kinetics. The basics of z one spending in chromatography have been illustrated in a dynamic and intuitive approach, prior to the use of phenomenological equations.
