✦ Synopsis

Gel chromatography is fractionally used in the fields of po!ymer chemistry and biological chemistry. Recent developments of column-packing materials have made the method applicable to compounds of iow molecular weight (mol_ wt_ several hundreds).

Most of the gel chromatographic

experiments reported in the literature involved the use of only a few kinds of solvent as eluents, in contrast to the variety of eluents being used in adsorption and partition chromatography. This fact suggests that little attention has been paid to solvent dependence in gel chromatography.

A few papers have dealt with this problem, using Sephadex LH-201>', polystyrene gels3*' or isodecylmethacrylate-divinylbenzene ge15. We have systematically investigated solvent dependence in the gel chromatographic behaviour of n-alkanes or metal fi-diketonato complexes with a poIy(viny1 acetate) gelclo.

This paper describes the gel chromatographic elution data for low-molecularweight n-alkanes on a polystyrene gel with different organic solvents.
