4. Concluding remarks
The present research has shown the advantages of using amul-
tidimensional GC system whe nthe sample under investigation is
highly complex.The MDGC– qMS/FID method developed enabled
the high-resolution separation of the santalol fraction,which
characterizes sandalwoodoil.Theresolving-power limitation of
monodimensional GC was avoided,enabling reliable identifica-
tion and quantitation of target analytes.The quality of a series of commercial samples was assessed on the basis of the ranges
reported by the International and Australian Standards.One of
the samples under investigation demonstrated to be a “fake” oil,
despite the quality certificate reported on the label.It can be
affirmed that heart-cutting MDGC is the multidimensional method
of choice when a limited number of first-dimension chromatog-
raphy bands requires separation on a full-length conventional
capillary.
