Large volume CIM® chromatographic monoliths – scalability and uniformity NEW!

To ensure the desired chromatographic characteristics of the CIM® monolithic column at large scales, monolith microstructure morphology, pore size distribution, porosity and surface ligand density should be uniform. To demonstrate the uniformity of large chromatographic monoliths we have developed new testing procedures. By fabricating smaller columns (disks) from different random  positions of larger monolith, non-cGMP compliant chromatographic testing can be applied on the same polymerization batch without affecting the cGMP compliance of large-scale chromatographic monolith. Each individual disk was thoroughly tested and the results were compared to the properties of the large monolith.
