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 pressu re 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.
