Abstract: There is disclosed a method of producing etched non-porous particles. The method includes, in some examples, coating a non-porous particle with a hydrophilic polymer and treating the coated particle with acid or base. Also provided is etched non-porous particles capable of separating a variety of analytes, including biomolecules.

Abstract: A column including particles having an average particle size ranging from about 1 μm to about 5 μm; the particles have an average pore size ranging from about 450 Å to about 3000 Å; and the particles have an average pore volume ranging from about 0.1 cm3/g to about 5 cm3/g is disclosed. The column can be a size exclusion chromatography column. The column can be used in a method to separate monomers from viral analytes, which is also disclosed.
