ResumoThe application of capillary column suprciritcal fluid chromatography (SFC) and supercritical fluid chromatography—mass spectrometry (SFC—MS) to the analysis of the polycyclic aromatic hydrocarbon fraction of selected marine diesel fuel samples is described. The chromatographic separation methods utilized pressure or density programming techniques and small diameter (50 μm) capillary columns. This work demonstrates the feasibility of achieving hihg-resolution separations of medium polarity compounds using nonpolar carbon dioxide as the mobile phase in SFC and the successful coupling of SFC to MS to obtain mass chromatograms and reliable chemical ionization mass spectra. High resolution separations of the polycyclic aromatic hydrocarbon fractions of marine diesel fuel samples were combined with isobutane chemical ionization MS. Analysis of the more polar components will require a more polar supercritical fluid mobile phase.
