GromSil 300 SEC is a size exclusion chromatography (SEC) column from Dr. Maisch HPLC GmbH, based on high-purity, fully porous silica with a 300 Å pore size. This wide-pore design allows efficient separation of high-molecular-weight compounds based purely on molecular size, making it ideal for the characterization of proteins, monoclonal antibodies, glycoproteins, and large synthetic polymers.
With minimal secondary interactions and high mechanical stability, this phase ensures reproducible retention times and accurate molecular weight profiling in both aqueous and organic solvent systems.
Thanks to its wide-pore structure and minimized surface interactions, GromSil 300 SEC from Dr. Maisch HPLC GmbH is the reliable choice for accurate and robust size exclusion separations of large biomolecules.
