  • Title: Application of the stoichiometric displacement model of retention to anion-exchange chromatography of nucleic acids.
    Author: Drager RR, Regnier FE.
    Journal: J Chromatogr; 1986 May 30; 359():147-55. PubMed ID: 3637180.
    Abstract:
    The stoichiometric displacement model has been refined in its application to anion-exchange chromatography. The revised stoichiometric displacement model has been shown to be valid for anion-exchange chromatography with respect to all particulars of the model tested. It has been shown that the use of displacing agent activity is not a necessary condition for valid application of the stoichiometric displacement model to anion-exchange chromatography. While the cation of the displacing salt can influence anion-exchange chromatography, the data indicate that the displacing anion is of primary importance. It has been shown that solutes with three-dimensional structure have Zn value to solute charge ratios less than unity, and that the stoichiometric displacement model may be useful as a probe of solute three-dimensional structure.
