CHROMATOGRAPHIC COLUMN AND METHODS FOR CONTROLLING SORBENT DENSITY |
摘要 |
Disclosed herein are apparatus and methods for mitigating column bed compression over time. This invention provides for an improved column design and method of controlling bed density in a chromatographic column using a protruding portion of a filter assembly. The invention results in a higher sorbent bed density than can normally be achieved using a fixed length column of conventional design. The invention may be implemented as a unique filter assembly or as a column tailored for the application and a matching filter assembly.
