Abstract
A device and a method for producing the device for use in a chromatographic system wherein a component of a mixture is partitioned 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 is modified to control the shape of the fron t of the traversing component by introducing along the edge either a plurality of indentations or a chemical substance.
