This paper will explore the characterization of coal-derived materials by High Resolution Mass Spectroscopy (HRMS). Coals are very complex and heterogeneous on both a microscopic and molecular level. The microscopic heterogeneity can be reduced by working with macerals separated from the whole coal. Macerals are the microscopically identifiable plant remains which make up the organic portion of coals. The molecular make up of the various macerals can be traced back to the original biomolecules and biomacromolecules. The extent of alteration depends on both the rank of the coal and the type of maceral, some of which are more resistant than others. Data from the analysis of whole coals and separated coals will be discussed. 22 refs., 17 figs., 6 tabs.
