Spectral Quality and Reproducibility in Thermal Modulation Comprehensive GCxGC-MS Mass Spectrometer Using a Rapid Scanning Quadrupole

Invented by J. Phillips in 1989, comprehensive GCXGC has strong chromatographic resolving power; from its original petrochemical applications it has been extended to many others. However, coelutions with matrix peaks are often observed and a higher separation power is required.

The coupling of GC×GC to mass spectrometry (MS) providesan additional dimension for the identification of compounds concealedunder contour plot displays used in GC×GC.
