Chromatography

aroma_ess

Gas phase chromatography uses sophisticated apparatus which enable each of the aromatic components of an EO- of which there are a large number- to be identified (up to 450 aromatic molecules)

A gas chromatography chart always shows a series of peaks, each one representing a very specific aromatic molecule that have been identified by powerful chromatography software.

Operating conditions

Mass spectrometry

Mass spectrometry reveals the quantity (%) of each one of the molecules identified. (Quantitative composition)
