## 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.
A method for the calibration of size-exclusion chromatographic columns is proposed that takes into account the nonlinear dependence of the Stokes radius \(R_{\text {* }}\) upon the partition coefficient \(K_{\mathrm{p}}\). The method is based on the assumption that the pore size distribution of a mo
