It is a specific branch of chromatography that does what it has to do in general very well – that is, separate a large number of molecules in a reasonable timeframe.

Chapter 3: Methods for essential oil analysis Chromatography, especially gas chromatography (GC) and mass spectroscopy (MS) have been the most applied analytical techniques for essential oil analysis4. Because of the complexity of essential oil compositions, there has been a high demand for sophisticated instruments to analyse them.

Capillary Gas chromatography-Mass spectrometry (GC-MS) proves to be an efficient and precise method for qualitative, as well as quantitative estimation, for almost all combinations of components in such mixtures down to minute traces.

The most commonly used capillary column for the analysis of essential oils is Polyethylene Glycol (PEG).File Size: KB. Bicchi, in Encyclopedia of Separation Science, Classical GC Analysis.

Essential oils are generally analysed by capillary GC. The most popular stationary phases used for essential oil analysis are methylpolysiloxanes (SE, OV-1, OV, DB-1, PS) and methylphenylpolysiloxanes (SE, SE, PS, DB-5) as apolar stationary phases; and polyethylene glycol (Carbowax 20M) as a.
