## Abstract Simultaneous use of large standard molecules and small particles of the product examined gives rise to errors in pore size determination by size exclusion chromatography. This error is calculated for packings of spherical particles, thus making corrections possible.
## Abstract The object of this study is to develop multidetector sizeβexclusion chromatography (SEC) methods to determine the number of arms per molecule across the molecular size distribution of starβbranched polymers. An empirical fit between the intrinsic viscosity molecular contraction factor _
