Abstract

The usual concepts of the dynamics of an overloaded solute band fail to explain several phenomena such as the typical β€œleading‐tail” shape and retention deviations exhibited by overloaded peaks, and why these defects are more commonly observed in short columns. These and other related deviations from theory can be rationalized by a non‐classical approach to the overloading phenomenon.

The elution profiles observed with overloaded capillary columns are well described by a four-parameter theoretical model derived from the basic mass balance equations which relies on an expansion of the partition isotherm to the second term and takes the sorption effect into account. The reliability
