Abstract
A device is disclosed for use in a chromatographic system wherein a component of a mixture is paritioned between a liquid phase and an immobile phase. The device is comprised of a chromatographic material. In the chromatographic system the component traverses at least a portion of the chromatographic material. The device generally has at least one longitudinal edge substantially corresponding to the direction of traverse of the component. The longitudinal edge includes means for controlling the shape of the front of the traversing component.

4. A device for use in a chromatographic system wherein a component of a mixture is partitioned between a liquid phase and an immobile phase, said device being comprised of a chromatographic material having a longitudinal edge, wherein in said system said component traverses at least a portion of said chromatographic material and said longitudinal edge includes means comprising a chemical substance capable of reducing the rate of migration of said traversing component along said edge for controlling the shape of the front of the traversing component.
- 11. A device for use in a chromatographic system wherein a component of a mixture is partitioned between a liquid phase and an immobile phase, said device being comprised of a chromatographic material and having a plurality of indentations along a longitudinal edge, the number, dimensions, and configuration of said indentations being sufficient to render the front of said traversing component substantially flat or convex.
- 19. A device for for use in a chromatographic system wherein a component in a liquid medium traverses at least a portion of said device, said device comprising at least one strip of a porous material, said strip having two longitudinal edges, said longitudinal edges having a plurality of indentations, the number, configuration, and dimensions of said indentations being sufficient to render the configuration of the front of said traversing component substantially flat or convex.
