TSKgel SCX (Na+)

TSKgel SCX (Na+) 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.
