  • Patent number: 5028696
    Abstract: A method of separating charged molecules having different numbers of charges thereon includes the step of passing the molecules to be separated through ion-exchange material such as an ion-exchange chromatograpy column in normal manner so that molecules to be separated bind to the ion-exchange material. Displacer molecules are then passed through the ion-exchange column to selectively release certain of the molecules to be separated from the ion-exchange material, while others of the molecules to be separated remain bound to the material.
