Abstract: 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 i s retained in a housing separate from any functional components of the conti nuous-flow system other than the prefilter element itself, the prefilter ele ment being separable from the other functional components to allow the prefi lter to be replaced without disturbing any other functional components.

Abstract translation: 如高性能液相色谱柱或柱所示的用于连续流动系统的预过滤器元件由在其厚度上具有平均孔径梯度的梯度过滤器构成，孔径在流动方向上减小。 该预滤器元件被保持在与预滤器元件本身不同的任何功能部件的外壳中，预滤器元件可与其他功能部件分离，以允许预滤器被替换而不干扰任何其他功能部件。
