A viable approach
for the determination of sources of essential oils based on automatic injection
solid-phase microextraction–chiral-gas chromatography–mass selective
detection is demonstrated. With no sample preparation, it is shown that the
source of essential oils such as peppermint, spearmint, and rosemary can be
easily distinguished. Short fiber exposure times of approximately 6 s to the
headspace above submicroliter quantities of the selected oils are all that is
required to obtain both the required sensitivity and resolution to afford analyses
with excellent reproducibilities (relative standard deviation values consistently
less than 5.0%).
