In the GPC analysis, the elution amount is determined using a known molecular weight marker, and a calibration curve is prepared by plotting the logarithm of the molecular weight on the vertical axis and the logarithm of the elution amount on the horizontal axis (holding time) before analyzing ...
In order to determine the molecular weight of a polymer by GPC in the low MW region, a secondary calibration method can be established when polymer standards of the analysed polymer are not available (1). The efficiency of this method has been checked for the system poly(methyl methacrylate)...

GPC研究结果表明随反应时间延长,聚合度增大,聚合物分子量趋于增大但分散性减小。 Instead, their test tube was filled with some "contaminant": Ahigh molecular weightpolymer they would soon identify as the first actin-binding protein, later called filamin A. ...
