Xtimate SEC column is based on porous silica particles matrix, with its surface protected by derivatization with diol functional ligands to prevent interactions with proteins. The dual-bonding mechanism minimizes nonspecific adsorption of water-soluble polymers, proteins, biomolecules, enzymes, and peptides. It is widely used for the separation and analysis of water-soluble polymers and biological macromolecules.
