Calibration Curves of Hydrophilic Polymers (3) (Poly(Sodium Methacrylate))
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.
