The present invention comprises an axial flow chromatography column 201 and methods for separating one or more analytes in a liquid by the use of such columns, and systems employing such columns. The column comprises opposed, axially spaced first and second end units 212, 213, comprising first and second ports respectively 233, 240; wherein the first port and said second port are at essentially the same level or elevation above the level of the bed space on the chromatography column. This is achieved using a passageway 242 extending between second end unit and the second port at the same height as the first port. |
