Calibration curves for Asahipak GF-HQ series using sodium poly(styrene sulfonate) are shown. Since Asahipak GF-HQ series can be used with both aqueous and organic solvents as the eluent, it is suitable for the analysis of hydrophilic polymers such as sodium poly(styrene sulfonate) or sodium polyacrylate. Several types of hydrophilic polymer standard are commercially available. It is recommended to use standard polymers similar to the analyte for the calibration curve.
