Ethylene Maleic Anhydride Copolymer
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.
