Gas chromatography with electron ionization and mass spectrometry (GC–EI-MS) detection is a workhorse among analytical techniques in metabolomics. A major challenge in the utilization of GC–EI-MS in metabolomics is the identification of unknowns.
The combination of GC with time-of-flight (TOF)-MS proves to be a successful approach for the challenging analysis of persistent organic pollutants in complex matrices such as sediment and fish samples.
