    摘要： Petroleum or other hydrocarbon samples can be analyzed in parallel by 1) GC-field ionization Time of Flight Mass Spectrometer (GC-FI-TOF MS) and 2) two dimensional gas chromatography (2D-GC) equipped with a flame ionization detector (FID). The combined techniques allow for improved quantitative characterization of the compounds within a hydrocarbon sample. The techniques can be combined by correlating the 2D-GC FID data with the GC-FI-TOF MS data based on correlation of compound classes, correlation of retention windows within a compound class, correlation of individual compounds, such as paraffins, or a combination thereof.

    摘要： This invention is a data processing/visualization method which includes the software development and operation to apply to any multi-dimensional separation. The GC-MS analysis of diesel is an example to demonstrate this software development and operation. The steps of this method includes (1) displaying the total ion chromatogram obtained from a GC-MS experiment, (2) displaying each mass spectrum versus retention time, (3) selecting a normal paraffin family as the reference compound family for relative polarity display, (4) transforming every mass slice to line-up normal paraffin compound family in the same relative retention time (position), (5) rotating the axis to best display the two (multi) dimensional data.
