Behavior of Micellar Solutions in Gel Permeation Chromatography. A Theory Based on a Simple Model

Abstract

Gel permeation chromatograms are interpreted in terms of V, the peak elution volume, which is characteristic for the size of the solute species. If solute association takes place, V may become extensively concentration dependent. To further the understanding of this effect a simple theory, which ignores axial diffusion, has been developed, the model for molecular association being a micellar surfactant in equilibrium with its monomer.
