Classification of the botanical origin of cinnamon by solid-phase microextraction and gas chromatography.

Solid-phase microextraction, or SPME, is a sample preparation technique used both in the laboratory and on-site.

Isolation of the compound remained elusive, until solid-phase microextraction was used to extract the volatile compounds, which were then analyzed using gas chromatography-mass spectrometry.

When this is done with small quantities of solid sorbents it is referred to as solid-phase microextraction (SPME).

Solid-phase microextraction (SPME) - This is based on adsorption of analytes onto a polymer-coated fibre or cartridge.

An adsorption extraction can be accomplished by passive headspace adsorption, passive headspace adsorption using Solid-phase microextraction (SPME) or dynamic headspace adsorption.
