Calibration Curves of Hydrophilic Polymers (1) (Sodium Poly(Styrene Sulfonate))

Since Asahipak GF-HQ series can be used with both aqueous and organic solvents, they are suited to the analysis of hydrophilic polymers such as sodium poly(styrene sulfonate) and sodium polyacrylate. Several kinds of pydrophilic polymer standard are commercially available. When analyzing a sample, a standard which resembles it in structure should be selected to obtain the calibration curve for the analysis.
