Ethylene Maleic Anhydride Copolymer (Comparison of KD-800 and SB-800 HQ)

Polymers, whose polarity is higher than that of DMF, are adsorbed by the packing materials of the OHpak SB-800 HQ columns. For such polymers, the use of the GPC KD-800 columns is recommended. On the other hand, for polymers having a lower polarity than that of DMF, the use of the SB-800 HQ columns is recommended.
