Continuous affinity chromatography using a magnetically stabilized fluidized bed.

A new processing tool, the magnetically stabilized fluidized bed, offers opportunities for efficient fluid-solids contact.The bubbling and mixing normally seen in a fluidized bed are eliminated, and continuous countercurrent contact is possible. This technique is especially suitable for biochemical separations, where cellular debris would clog an ordinary fixed bed. Preliminary modeling and experimental work on such a system is discussed, along with details of a relatively simple experimental system.
