Removal of Particulates from Samples for HPLC

One area is analytical separations by inorganic membranes as part of sample cleanup. For example, it is imperative that a high performance liquid chromatography (HPLC) 

Molecularly bonded silver membranes have also been used to purify aggressive HPLC solvents [Minneci and Paulson, 1988]. Similar to the anodic alumina membranes, silver membranes are preferred for this application due to the following reasons high chemical and thermal stabilities leading to no or negligible amount of dissolved or leached membrane constituents in the solvents.
