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 calibration curve with PS is almost as same as that with PEG and PEO.
Sample :
PEG Poly(ethylene glycol),
