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.
