  • Crescent plot columns and methods for preparing crescent plot columns
    Patent number: 10948465
    Abstract: A crescent PLOT column is disclosed, including a capillary column having an inlet, an outlet, a bore, and an inner surface surrounding the bore and extending between the inlet and the outlet. A layer of particles is localized on a radial portion of the inner surface. The layer of the particles includes a radial thickness decreasing from a center of the radial portion to a periphery of the radial portion, forming a crescent shape in a radial frame of reference. A method for preparing the crescent PLOT column is disclosed, including loading the capillary column with a fluid including a carrier and particles such that the fluid is contained within the capillary column. The capillary column and the fluid contained within the capillary column are subjected to a centrifugal force. The carrier is removed, and a layer of the particles is localized on the radial portion of the inner surface.
