TSKgel SCX
The TSKgel SCX column is packed with porous polystyrene divinylbenzene polymer beads of which the surface has been modified with strong cation exchange groups that are surrounded by Na+ counterions. This column is optimized for the separation and analysis of organic acids, saccharides, and alcohols.
The TSKgel SCX column is also available in the H+ form for the separation of isomerized sugars, alcohols, and lower organic acids.
