Abstract:
In this work a thermal modulator GCxGC system was interfaced to a high-resolution time-of-flight mass spectrometer (HRTOFMS) in order to analyze petroleum samples by using electron ionization (EI), field ionization (FI), photoionization (PI), and chemical ionization (CI). Additionally, the GC-MS interface was modified to increase the temperature in this region so that higher boiling point compounds could be analyzed by the GCxGC-HRTOFMS system. A comparison among the different ionization techniques as well as the improvements in the results for the range of compounds measured will be presented.
