General
YMC-BioPro series ion exchange columns are available in QA and SP chemistries and are based on 5 micron porous (QA or SP columns) or nonporous (QA-F and SP-F columns) hydrophilic polymer beads. The porous materials offer excellent binding capacity with unusually high efficiency, and low operating pressure when packed in 50 x 4.6 mm columns. The non porous particles offer high efficiency, exceptional resolution, and low operating pressures in 30 x 4.6 mm and 100 x 4.6 mm columns.
