Abstract A fractionation procedure using Sephadex LH-20 gel provides a gentle, preparative scale (grams), chemical class separation for a shale-derived crude oil and a coal-derived oil. The procedure involves three steps using the gel in different modes: (1) lipophilic-hydrophilic partitioning using the gel swollen with methanol-water and eluted with hexane, (2) molecular size separation using the gel swollen with tetrahydrofuran (THF) and eluted with the same, and (3) aliphatic-aromatic separation using the gel swollen with isopropanol and eluted with the same. Large samples can be separated with essentially quantitative recovery for the first two steps and a reproducibility of the gravimetric yields of approximately 2 percent. This procedure is designed to produce large quantities of fractions for biological testing with minimal alteration of sample composition.
