CHROMATOGRAPHY FILTER

A filter for a chromatography system includes a filter body having an exterior wall, a cavity, an interior wall surrounding the cavity and a channel extending between the exterior and interior walls. The channel passes a flow of a liquid from the cavity. The filter body is formed of a sintered metal oxide material and has a pore size that is less than a particle size to be filtered liquid. In some embodiments the filter body is formed of zirconium oxide or aluminum oxide. The filters reduce or eliminate the types of reactions that occur between conventional filter bodies and chromatographic solvents and samples. The filters can be used at different locations in a chromatography system to remove particles that may be present in sources of chromatographic solvents or introduced into the chromatographic system flow by chromatographic components, such as pumps, valves and other chromatographic system components.
