Shim-pack Bio IEX Columns

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.
