Using GC-TOF-MS, 571 peaks were extracted, of which 189 metabolites were tentatively identified. On the other hand, 364 and 277 metabolites were tentatively identified in the positive and negative ionization modes of the UHPLC-QTOF-MS/MS, respectively.

An application note from JSB studies the feasibility of coupling GCxGC with QTOF detection in MS/MS mode. GC-QTOF is a valuable technique for challenging applications that demand confident identification in highly complex matrices, such as, metabolomics and pesticides analysis. For 3 samples, the mass spectra were the same on GC-MS and on GC-QTOF with acetylation, but different without acetylation. Except the type of detection, the only difference in analytical conditions between the two methods was injection temperature: 280 °C for GC-MS and 260 °C for GC-QTOF.

History of LC-MS. The coupling of chromatography with MS is a well developed chemical analysis strategy dating back from the 1950s. Gas chromatography (GC)–MS was originally introduced in 1952, when A. T. James and A. J. P. Martin were trying to develop tandem separation - mass analysis techniques.
