The effect of pH, salt concentration and temperature on molecular weight estimation of water-soluble ones is presented. In addition, novel utilizations of GPC with dual detectors are reviewed. Calibration methodologies in GPC, including various instrumental method and director calibration, as well as universal calibration are reviewed. With the combination of multi-detectors, the performance of one detector could be effectively checked against others and the estimated molecular weights of polymer tend to be reliable and precise. 查看全文查看/发表评论下载PDF阅读器 相关附件：附件1附件1附件2附件3版权转让声明书 -->
