Process scale-up tends to be rather easy in adsorptive membrane chromatography, at least compared to the use of conventional beaded resins as the chromato-graphic support. It has been demonstrated that the diameter of a stack of disc membranes can be increased by up to one order of magnitude and more, with the dynamic capacity remaining constant. This allows for the processing of considerably larger sample volumes at higher flow rates. With radial flow membranes, when both the height and diameter of the cartridge were increased and the flow rate adjusted proportionally to the increased cartridige volume, the apparent specific capacity decreased only slightly.
