WebExpanded bed chromatography is a mode which allows the direct processing of crude suspensions. (Roy et al., 2005; Sonnenfeld and Thömmes, 2007). It uses a fluidized bed but the hydrodynamic properties of the chromatography medium are such that it behaves like a packed bed (i.e. there is no back mixing of the beads). WebFull Article.
