Thermo Scientific Q-Exactive Orbitrap Gas Chromatography/Tandem Mass Spectrometer

The hybrid quadrupole-Orbitrap enables both targeted and non-targeted screening and characterization of volatile compounds. Sample components are separated by GC and ionized by electron-impact for in-source fragmentation, or chemical ionization for soft-ionization.

Our Group has used the GC-Orbitrap for many projects, including:

• Suspect screening of pesticides in soil and water samples.
• Profiling PAH emissions from various point-sources
