Solid phase microextraction-comprehensive two-dimensional gas chromatography?time-of-flight mass spectrometry for the analysis of honey volatiles

Popis výsledku v původním jazyce

Head-space solid phase microextration (SPME), followed by comprehensive two-dimensional gas chromatography-time-of-flight mass spectrometry (GC x GC-TOFMS), has been implemented for the analysis of honey volatiles, with emphasis on the optimal selectionof SPME fibre and the first- and second-dimension GC capillaries. From seven SPME fibres investigated, a divinylbenzene/Carboxen/polydimethylsiloxane (DVB/CAR/PDMS) 50/30 mu m fibre provided the best sorption capacity and the broadest range of volatilesextracted from the headspace of a mixed honey sample. A combination of DB-5ms x SUPELCOWAX 10 columns enabled the best resolution of sample components compared to the other two tested column configurations. Employing this powerful analytical strategy ledto the identification of 164 volatile compounds present in a honey mixture during a 19-min GC run. Combination of this simple and inexpensive SPME-based sampling/concentration technique with the advanced separation/identification approac
