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 calibated simultane-ously with narrow MWD polystyrene samples by coupling technique.
