Graded external prefilter element for continuous-flow systems

A prefilter element for continuous flow systems as illustrated by a high-performance liquid chromatography cartridge or column is constructed with a gradient filter that has a gradient in average pore size over its thickness, the pore size decreasing in the direction of flow. This prefilter element...

Summary:A prefilter element for continuous flow systems as illustrated by a high-performance liquid chromatography cartridge or column is constructed with a gradient filter that has a gradient in average pore size over its thickness, the pore size decreasing in the direction of flow. This prefilter element is retained in a housing separate from any functional components of the continuous-flow system other than the prefilter element itself, the prefilter element being separable from the other functional components to allow the prefilter to be replaced without disturbing any other functional components.
