Selection of Column (3) (Poly(Sodium Methacrylate))

Calibration curves of Asahipak GF-7M HQ (packed with poly(vinyl alcohol)) and OHpak SB-806M HQ (packed with poly(hydroxy methacrylate)) are compared using a hydrophilic polymer standerd, poly(sodium methacrylate). The comparison shows that the calibration curve of Asahipak GF-7M HQ is more linear than that of OHpak SB-806M HQ.
