Diesel Fuel Classification Analysis Using GC x GC/FI and Kendrick Mass Defect Plots
Comprehensive two-dimensional gas chromatography (GC x GC) in combination with high-resolution mass spectrometry is a powerful tool for the analysis of complex mixtures.
In this work, we analyzed a diesel fuel sample by using GC x GC in combination with a new high-resolution time-of-flight mass spectrometer (HR-TOFMS) . Field ionization (FI) produced molecular ions for all components and exact mass measurements were used to obtain elemental compositions. A traditional Kendrick Mass Defect (KMD) plot was used to identify hydrocarbon groups in the diesel fuel sample.
A commercially available diesel fuel sample was analyzed with the JEOL AccuTOF™ GCx equipped with a Zoex ZX2 thermal modulator and experimental GC Image software (version 2.5.0a2).
