Abstract
Chromatography devices contain chromatography media and methods of making and methods of using chromatography devices. Chromatography devices enable a more efficient, productive and/or environmentally friendly chromatographic operation due to one or more of the following advantages over conventional chromatographic operations: elimination of a device packing step by the user; elimination of clean-in-place (CIP) steps; elimination of clean-in-place (CIP) steps utilizing sodium hydroxide solution; elimination of any validation steps by the user; and use of a chromatography device comprising biodegradable material. The chromatography media includes porous inorganic particles having a functionalized surface and having a median pore size of at least about 300 Angstroms (A), or at least about 300 A up to about 3000 A. The inorganic particles may have a BET surface area of at least about 20 m2/g, or at least about 25 m2/g, or about 30 m2/g, up to about 2000 m2/g.
