Chapters
Introduction
Contnend
Fuel Production Processes
Full absolute quantification of Diesel fuel by GCxGC-TOFMS
Mass spectrometric scripting
Quantification
Comparison to DIN EN 12916 (Aromatics by LC Method)
Comparison to DIN EN 14078 and 14103 (FAME, IR and GC)
Analysis of the aromatic composition of Heavy fuel Oil by GCxGC-HRTOFMS
Selectivity of GCxGC-TOFMS and GCxGC-HRTOFMS for the identification of compounds
Graphical/Visualization methods for the interpretation of GCxGC-TOFMS Data-unit resolution
The accessibility of accurate mass information allow additional types of structural visualization
Accurate mass information could be used to calculate elemental composition and Kendrick mass defect by the verified M+ peaks
Isomer number information from GCxGC seq. can be also directly integrated into Kendrick mass defect plot and ralted plots
Mass defect information could be also be integrated with the 2D chromatographic data in 3D representation
Investigation of Fischer-Tropsch syncrude oil by GCxGC-HRTOFMS
Fragments of many compounds class retain Kendrick mass defect
Excursion: GCxGC-VUV detection-> A good addition to GCxGC-HRMS
Temperature variations in FT
