Buckminsterfullerene C60 was used as a stationary phase for the microcolumn liquid chromatographic separation (LC) of various aromatic compounds. Carbonaceous material prepared by a general soot production process was extracted with toluene, purified using several chromatographic processes, and then packed into fused silica capillary columns for chromatographic evaluation. The performance and separation characteristics were examined. The results indicate that the C60 fullerene can be useful as an LC stationary phase and offers a unique shape selectivity for aromatic compounds as compared to conventional octadecylsilica phases.
