Abstract

Methods and devices are disclosed for a separation device. A separation device includes a plurality stacked modules and a distribution network including an inter-module LEVEL-1 distributor an intermediate LEVEL-2 distributor and a planar LEVEL-3 distributor. The distribution network enables streamline lengths which are approximately equal and induces uniform velocity fluid flow. These features provide a narrow residence time distribution providing improved chromatographic performance.
