Abstract
The present invention discloses methods for packing chromatography columns using dual-purpose valve assemblies. The key components of the dual-purpose valve comprise of the following; the inlet port (224) which sits on the first adaptor (212), the hollow nozzle (320) which passes through the first adaptor (212) cavity and is closed on the bottom end, and the internal movable plug (322). Different components of our de-vice work in way that the mobile phase and analyte(s) distribution is not blocked in the centre of the column, allowing for a uniform and homogeneous fluid distribution. This simple yet novel design offers uniform fluid distribution, stable packed bed, eliminates any void volume, and prevents bacterial contamination/growth. Ease of use, scalability, ease of cleaning, cost-efficiency and fine-tuning packing conditions such as pressure are key features of this invention.
