  • Molecular separation column and use thereof
    Patent number: 4512897
    Abstract: A molecular separation column for effecting the differential distribution, between two phases, of the components of a sample flowing therethrough. The column contains a substantially homogenous solid stationary phase which comprises a porous matrix of fiber having particulate immobilized therein, wherein at least one of said fiber or particulate is effective for molecular separation. The column is characterized by a reduced pressure drop, increased axial dispersion, more uniform peak shapes and better separations at high sample loading.
    Type: Grant
    Filed: April 20, 1983
    Date of Patent: April 23, 1985
    Assignee: AMF Incorporated
    Inventors: Alvin L. Crowder, III, Nils L. Dailey, Joseph V. Fiore, Kenneth C. Hou
  • Molecular separation column and use thereof
    Patent number: 4384957
    Abstract: A molecular separation chromotography column for effecting the differential distribution, between two phases, of the components of a sample flowing therethrough. The column contains a substantially homogeneous solid stationary phase which comprises a porous matrix of fiber having particulate immobilized therein, wherein at least one of said fiber or particulate is effective for molecular separation. The column is characterized by a reduced pressure drop, increased axial dispersion, more uniform peak shapes and better separations at high sample loading.
