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 curve with PS is almost as same as that with PEG and PEO.
Please refer to Polystyrene Standards (9) (KD-802).
