THE MOLECULAR WEIGHT DEPENDENCE OF THE SPREADING FACTOR OF SEC COLUMNS AND THE SURFACE STRUCTURE OF THE PORE OF PACKINGS

CHENG Rongshi ,
BO Shuqin

Received Date: 19 August 1984

The molecular weight separation and column dispersion for a number of SEC columns packedwith various packing materials were calibrated simultaneously using narrow MWD polystyrene stan-dards as probe. The molecular weight dependence of the spreading factor is closely related to thesurface structure in the pore of packings.
