Abstract
A simplified analysis of chromatographic-column dynamics based on a si milarity equation (found experimentally) for outlet chromatograms of s ize-exclusion columns is developed. A theoretical explanation of the s imilarity equations is developed in the case of a convection-diffusion model. A criterion for validating the similarity results is proposed. As a corollary of the above analysis, an integral method for evaluati ng the variance is proposed.
