Hydrocarbon analysis by mass spectrometry in the past few decades was performed on beam type instruments such as magnetic sector or quadrupole mass spectrometers. Only recently have a few works of hydrocarbon analysis utilizing a quadrupole ion trap devices been reported. However, until recently, commercial ion trap mass spectrometers were operated conventionally, where the ion trap device was simultaneously used as ion source and mass analyzer. The present work was conducted on the GCQ, which decouples the ion source from the ion trap device as mass analyzer. This external ionization technique offers the leverage of temperature controlling of the ion source independently from the ion trap manifold. The ions generated in the ion source are injected into the ion trap via a lens system and controlled by radio frequency (RF) using the waveforms technique. The ion population is controlled by instrument software.
