Abstract:
To chemically characterize complex samples such as fuels, with often isobaric species, detection techniques such as high-resolution accurate mass (HRAM) mass spectrometry can be used to help identify compounds. GC×GC is a technique that allows for separation of a samples chemical components by two different column phases, increasing the potential chromatographic resolving power by an order of magnitude. A key part of any GC×GC system is the modulator. To retain the separation achieved in the first column, the analytes must be introduced in narrow bands to the 2nd dimension column where they are further separated. The objective of this study was to evaluate the performance of GC-Orbitrap MS with flow modulated GCxGC by assessing key analytical parameters.
