A rapid, simple chromatographic procedure has been developed to fractionate coal-derived solids and liquids for subsequent analysis by mass spectrometry and other spectral methods. The sample is pre-adsorbed on neutral alumina (activity I), and eluted with hexane, toluene, chloroform (2 fractions) and 9:1 tetrahydrofuran-ethanol. The principal compound types eluted in each fraction, respectively, are: saturated hydrocarbons, aromatic hydrocarbons and benzofurans, ethers, nitrogen compounds, and hydroxyl compounds. Mass spectral analysis is enhanced because the toluene eluate contains only aromatic hydrocarbons and ethers, while the second chloroform fraction includes almost all of the nitrogen compounds in the sample.
