Comparison of Calibration Curves for KD-800 Series and SB-800 HQ Series (DMF Eluent)

Calibration curves for GPC KD-800 series and OHpak SB-800 HQseries are shown. Compared with the KD-800 columns, the SB-800 HQ columns perform better over a low molecular weight range.


Sample :
PEO, Poly(ethylene oxide)
