The nature of molecules with heteroatom functionality in the pyridine, extracts of the Argonne Premium Coal Samples is being explored using high resolution mass spectrometry (FIRMS), with desorption chemical ionization (DCI). Structural information is obtained from tandem MS experiments using high resolution to select the ions to fragment. The first DCIHRMS spectra of complex mixtures are shown. Molecular weight distribution determined by DO are similar to those determined by laser desorption and field ionization mass spectrometry with very little ion intensity observed at greater than 1000 Daltons. Results are correlated with other techniques such as NMR, XPS, and XANES.
