Exploring multiple-cumulative trapping solid-phase microextraction for olive oil aroma profiling

Headspace solid-phasemicroextraction is a solvent-free sample preparation technique
that is based on the equilibrium among a three-phase system, i.e., sample-headspacefiber.
A compromise between sensitivity and extraction time is usually needed to
optimize the sample throughput, especially when a large number of samples are analyzed,
as usually the case in cross-samples studies. This work explores the capability
of multiple-cumulative trapping solid-phase microextraction on the characterization
of the aroma profiling of olive oils, exploiting the automation capability of a novel
headspace autosampler. It was shown that multiple-cumulative solid-phase microextraction
has the potential to improve the overall sensitivity and burst the level of information
for cross-sample studies by using cumulative shorter extraction times.
