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). WebIntroduction. As a fluid passes through a packed bed it experiences pressure loss due to factors such as friction. The relationships required to predict the pressure drop for a fluid flowing through a packed bed have been known for some time, with Darcy observing in 1896 that the laminar flow of water through a bed of sand was governed by the following …
