  • Hybrid ligand and liquid chromatography stationary phase including hybrid ligand
    Patent number: 11786842
    Abstract: A composition includes a hybrid ligand. The hybrid ligand includes an amine group, an amide group or a sulfonamide group, and hydroxyl groups. A first method includes providing a solution containing a first polar analyte and a second polar analyte, applying the solution to a stationary phase including an immobilized hybrid ligand, applying an elution solvent to the stationary phase such that the first polar analyte and the second polar analyte pass through the stationary phase with different elution times, and collecting the first polar analyte at a first elution time and collecting the second polar analyte at a second elution time after the first elution time. A device of a packed column, a cartridge, a tube, a well plate, a membrane, or a planar thin-layer chromatography plate includes a solid support and a hybrid ligand coupled to the solid support. A second method forms an immobilized hybrid ligand.
    Type: Grant
