Comprehensive 2D GC-QPMS with Differential Flow Modulation


Shellie, RA, Comprehensive 2D GC-QPMS with Differential Flow Modulation, LC GC Europe, 21, (11) pp. 572-579. ISSN 1471-6577 (2008) [Refereed Article]


Differential flow modulation is an inexpensive way to perform GCxGC separations which has been attracting growing attention recently. Differential flow modulation uses high carrier gas flow rates in the second dimension column so it is widely thought that this rules out direct coupling with mass spectrometry. However direct coupled GCxGC-QPMS using differential flow modulation is reported here for the first time using an unmodified mass spectrometer comprising a dual inlet turbomolecular pump and fast scanning quadrupole mass analyser. The suitability of the approach for characterization of essential oils is demonstrated.
