These columns can reduce particle size from 5 μm to 2 μm to greatly improve the resolution between aggregates and monomers. Users can also reduce the column length from 300 mm to 150 mm using a 2 μm particle to achieve a 50 percent shorter run time while maintaining resolution.

Shim-pack Bio IEX Ion Exchange Columns are available in Q (quaternary ammonium) and SP (sulfopropyl) chemistries and are based on porous (Q and SP columns) and non-porous (Q-NP and SP-NP columns) hydrophilic polymers with low nonspecific adsorption. The porous particles offer excellent binding capacity with exceptionally high efficiency, and the non-porous particles offer high efficiency and exceptional resolution.
