Peculiarities in gel permeation chromatography of flexible-chain polymers on macroporous swelling sorbents.
In gel permeation chromatography on macroporous swelling sorbents, deviations from the Benoit principle of universal calibration were observed. It is suggested that these are caused by different degrees of thermodynamic compatibility of the eluted polymers with the sorbent matrix.
