Bianchi, Federica published the artcileComparison of comprehensive two-dimensional gas chromatography-time-of-flight mass spectrometry and gas chromatography-mass spectrometry for the qualitative characterisation of roasted barley by solid-phase microextraction, Name: 4,5-Dimethyloxazole, the publication is Journal of Separation Science (2007), 30(4), 527-533, database is CAplus and MEDLINE.
Volatile compounds of roasted barley used in the production of barley coffee, the most common coffee substitute, were analyzed by using solid-phase microextraction (SPME) followed by GC-MS and comprehensive GC × GC-TOF-MS, resp. The optimized SPME extraction conditions in terms of selection of the fiber coating, extraction time and extraction temperature allowed to obtain the highest GC response, thus enhancing the identification capabilities of the developed method. As for the SPME-GC × GC-TOF-MS anal., 64 compounds with similarity, reverse and probability values above 800, 900 and 6000, resp., were identified, by using a polar × apolar column set combination; in contrast, GC-MS was able to identify a lower number of compounds, i.e. 40 volatiles.
