【摘要】 本文讨论了凝胶色谱仪-毛细管粘度计联用时,实验数据的处理,连接管道死体积、虹吸管的残留体积等对特性粘数及其淋出体积的关系,并给出了改正方法和数学公式。通过窄分布的聚苯乙烯试样的实验数据,利用实测关系[?](V)与单分散校准关系[?](V_R)间的理论联系,对凝胶色谱柱组的分离和扩展效应同时作出了校准。更多还原

【Abstract】 The procedure of treatment of data obtained by coupling GPC with capillary vi-scometer was discussed in detail. Methods and mathematical formulas for correcting the effect of the dead volume of the connecting tube and the residual volume of the syphone tube on the intrinsic viscosity and its correlation with elution volume were given. With the aid of the theoretical relationship between the experimental relation [η] (V) and the calibration function [η] (VR) for the monodisperse species, the separation and the column dispersion of the GPC columns used were calibrated simultaneously with narrow MWD polystyrene samples by coupling technique.更多还原
