ABSTRACT:
A permselective assembly for the selective transport of a species of interest across a semipermeable ion, exchange barrier and a method of operating the same are disclosed. The assembly includes an inner tube of a permselective material disposed within the inner volume of an outer tube of a permselective material forming an annular channel therebetween. This annular dual tube arrangement decreased the hold up volume of the outer tube and increases efficiency of transport of the species of interest.
