✦ Synopsis
In this work a comprehensive two-dimensional system (GC6GC) was coupled to a time-of-flight mass spectrometer (TOF/MS) for the analysis of oil samples. Group-types like the alkanes and saturated cyclic compounds (naphthenes), which are present in oil, are shown separately by selecting their unique masses. On selecting appropriate ion fragments, this method also permits the determination of sulfurand oxygen-containing species in oil. Former results obtained by FID detection could be confirmed. After proper selection of unique ions in GC6GC-TOF both selectivity and sensitivity increase.
