REDUCTION IN BACK PRESSURE BUILDUP IN CHROMATOGRAPHY BY USE OF GRADED FILTER MEDIA

摘要

Cartridges for high performance liquid chromatography are designed for use with a large number of repeated injections without excessive buildup of back pressure by the inclusion of a filter medium consisting of sintered stainless steel fibers formed into a non-woven structure whose pore size decreases in the direction of flow down to a pore size of less than ten microns.
