Four coal gasification wastewater samples were analyzed for nonvolatile and polar organics by liquid chromatography-mass spectrometry (LC/MS). Samples were separated on a reverse phase liquid chromatographic column using an aqueous solvent as the eluant. A special spray deposition device was constructed to spray the LC effluent as an aerosol on a Finnigan moving belt LC/MS interface. The evaporated solute on the belt was fed directly to an MS for spectral analysis. In addition to several common organics such as phenol, guaiacol, methyl and dimethyl phenols, seven polar compounds were found, and the mass spectrum of each of these was obtained. They could not be identified, however, using available literature or data bases. The LC aerosol deposition device constructed for the study shows good potential for introducing aqueous eluants on a moving belt LC/MS interface.
