Abstract
A chromatography column includes a tubular member with an inlet end and a slidable porous member that bounds a chromatography media. The porous member is spaced sufficiently from the inlet end to define a receiving region.
Claims18
A chromatography column for accepting a sample module comprising:
- a tubular member having an inlet end, an outlet end, and an inner surface;
- first and second porous members disposed within said tubular member;
- and
- a chromatography media disposed within said tubular member and bounded by said first and second porous members;
- wherein said first porous member abuts said chromatography media and said first porous member is also in downwardly slidable contact with said inner surface of said tubular member and is spaced sufficiently from said inlet end to define a module receiving region for receiving a sample module entirely within said tubular member.

A chromatography column for use with a sample module comprising:
- a tubular member having an inlet end, an inner surface, and a module receiving region, said module receiving region being bounded by said inlet end and by a porous member;
- a chromatography media inside said tubular member, said chromatography media being bounded by said porous member;
- wherein said porous member abuts said chromatography media and said first porous member is also in downwardly slidable contact with said inner surface of said tubular member and is spaced sufficiently from said inlet end so that said module receiving region is deep enough to permit a sample module to be inserted completely into said receiving region.
A chromatography column for accepting a sample module comprising:
- a tubular member having an inlet end, an outlet end, and an inner surface said tubular member having a chamfered region near said inlet end;
- first and second porous members disposed within said tubular member;
- and
- a chromatography media disposed within said tubular member and between said first and second porous members;
- wherein said first porous member is slidably fitted within said tubular member and is spaced sufficiently from said inlet end to define a module receiving region for receiving a sample module entirely within said tubular member.
