LIQUID CHROMATOGRAPHY COLUMN

摘要

The invention relates to a chromatography column comprised of a column tube having liquid flow inlet and outlet means at substantially opposite ends, wherein the column tube comprises a chromatography matrix and wherein the column has distributor means located adjacent to said inlet and outlet means. Further, the column comprises a chromatography matrix of porous substantially non-magnetic particles having a size distribution of 45-165 µm, wherein the particle surfaces present immobilised ni-trilotriacetic acid (NTA) ligands; and adjacent to the outlet distributor means is a deep filter unit having a pore distribution of 20-130 µm
