The Elution Problem

Advances in Membrane Architecture and Flow Distribution

Membrane chromatography can run at flow rates packed-bed resins can't sustain, but early formats were used primarily for flow-through polishing, not bind-and-elute. A new technical article from Donaldson Life Sciences traces the two root causes behind inconsistent membrane performance, pore structure and device flow path, and details the new engineering changes designed to address them.

The article covers surface-localized functionalization, peak performance data for Purexa™ Process 50 MCP, and the device-level engineering behind even flow distribution across the membrane.
