Tunable affinity-based separations

By increasing the membrane-solute affinity for one specific solute, this solute can be separated from other solutes, even though their size and molecular structure are very similar. This can be considered as the membrane version of chromatography, but with the advantage of continuous processing.

Examples: the separation of the wanted catalyst in a mixture of phosphine-ligands, the isolation of active pharmaceutical ingredients (API) in co-presence of nearly identical by-products of its synthesis, …
