Normal-phase liquid chromatography has been used to separate nitrogen heterocyclics and aromatics with polar groups which are known to be present together in solvent refined coal. The identification of the separated components was accomplished by on-line coupling of the Fourier transform infrared spectrometer as a chromatographic detector. The separation of these model compounds was carried out using Li Chrosorb NH/sub 2/ and CN in series. Chloroform was used as mobile phase. All the compounds could be identified in spite of incomplete separation in some cases. A suitable interface adapted to the different methods of HPLC and FTIR allowed the detection of about 5 ..mu..g per injected compound.
