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.

Abstract: A device for dispensing liquid material is disclosed having an ampoule with at least four storage lumens, a mixing tip coupled to a distal end of the storage lumens, and an outlet lumen in fluid communication with storage lumens via the mixing tip. The at least four storage lumens extend axially along the length of an ampoule body, and the mixing tip has at least four gasket seats formed therein, each gasket seat corresponding to one of the storage lumens. The device also includes a first fluid provided in one of the storage lumens and a second fluid having a characteristic different from the first fluid provided in another of the storage lumens. Each of the storage lumens has a proximal gasket sealing the fluids from a proximal end of the ampoule and a distal gasket sealing the fluids from a distal end of the ampoule.
