| Comparison of Calibration Curves for KD-802.5 and SB-802.5 HQ (DMF Eluent: PEG, PEO and PS) | 
For the calibration curve for GPC KD-802.5 , PEG and PEO 
should be used as the standards. The calibration curve with PS is far different 
from that with PEG and PEO. For the calibration curve for OHpak SB-802.5 
HQ, both PEG, PEO and PS can be used as the standards. The calibataion cuve 
with PS is almost as same as that with PEG and PEO.
