“…Furthermore, the chromatographic peaks are compressed into highly focused pulses, as a result of zone compression occurring at the modulator, enhancing peak detectability. Overall, GC×GC is a particularly valuable technique for separating complex mixtures and has been applied in many fields where conventional 1D separations are used, such as food and flavour [27,28], environmental studies [29], metabolomics [30], petroleum products [31][32][33], and forensic science [34,35], including decomposition odour profiling [4,17,18,[20][21][22][23][24][25].…”

following data processing. Future GC-qMS results could be improved by implementing some of these softwareassociated procedures, potentially reducing the magnitude of variation observed between GC-qMS and GC×GC-TOFMS studies. One-dimensional GC analysis may also benefit substantially from coupling with TOFMS detection to provide an indirect increase in peak capacity using deconvolution. However, the wealth of information gained by using GC×GC-TOFMS in decomposition odour profiling is undoubtedly an asset in this field of research.

“…The structured elution order greatly improved the certainty in compound identification, holding promise for the detailed elucidation of the chemical alteration of anthocyanins during wine aging. In all applications the choice of RP-LC separations in the 2 D analysis lies in the compatibility with MS detection and the possibility to attain very fast separations Tranchida et al, 2013), although HILIC was also employed for fast 2 D analysis prior to MS detection (Fu et al, 2012).…”

“…Summarizing, the identification process was based on (1) comparison of unknown mass spectra and their retention indices with those listed in a dedicated database (FAMEs library, 2011); (2) observation of groups located in the GC × GC chromatogram; (3) comparison of present findings with those derived from previous research on the same topic [14,15]. Thanks to the GC × GC-MS analysis, it was possible to confirm the identity of many fatty acids determined by conventional GC with some level of uncertainty.…”

Fish oil made from menhaden (Brevoortia tyrannus) can be used as a dietary supplement for the presence of high levels of the long-chained omega-3 fatty acids, viz. epentaenoic and docosahexanoic. In this work, for the first time, two different multidimensional approaches were developed and compared, in terms of peak capacity, for triacylglycerol characterization. In particular, silver ion chromatography with a silver-ion column and non-aqueous reverse-phase liquid chromatography with a C18 column were tested in both comprehensive (stop-flow) and off-line modes. The use of mass spectra attained by atmospheric pressure chemical ionization for both LC approaches, and the fatty acids methyl esters profile of menhaden oil obtained by gas chromatography analysis, greatly supported the elucidation of the triacylglycerol content in menhaden oil. The off-line approach afforded a better separation and, thus, higher peak capacity to allow identifying and semiquantifying more than 250 triacylglycerols. Such a huge number has never been reported for a menhaden oil sample.The main disadvantage of such an approach over the stop-flow one was the longer analysis time, mainly attributable to solvent exchange between the two dimensions.
