1. Chromatography apparatus comprising, in combination,a chromatographic body formed as a substantially uniformly distributed multiplicity of rigid, solid, porous particles with chromatographically active surfaces, said particles having average diameters of greater than about 30 μ

  • m, the interstitial volume between said particles being not less than about 45% of the total volume of said column; and

    means for loading said surfaces with at least one solute that is reactive with said surfaces, by flowing a liquid mixture containing said solute through said body at a velocity sufficient to induce flow of said mixture within at least a substantial portion of said interstitial volume at a reduced velocity greater than about 5,000.
