NUCLEOGEL®

Sulfonated spherical PS/DVB resins in different ionic forms: mean particle size 10 µm, pore size 100 Å. Separation mechanism includes steric exclusion, ligand exchange and partition effects, ligand exchange being the predominant force, since the hydrated metal ions form strong interactions with the hydroxyl groups of the sample molecules. The intensity of these interactions decreases in the sequence Pb, Ca, Na.
