ABSTRACT:
A simulated moving bed apparatus and methods are described for continuously separating a target molecule from a liquid mixture, using a simulated moving bed system. The simulated moving bed system includes a plurality of filter cartridge modules in serial fluid communication. Each filter cartridge module includes a volume of stationary phase particulates adjacent a porous substrate layer. Each filter cartridge module also includes recirculation piping in fluid connection with a filter cartridge outlet and a filter cartridge inlet.
