New Technologies For The High-Speed Characterization and Analysis Of Essential Oils
By: Tincuta Veriotti, Megan McGuigan and Richard S…
Dramatic reductions in characterization and analysis times for essential oils were achieved using high speed gas chromatography (HSGC) and time-of-flight mass spectrometry (TOFMS). High-speed separations were achieved with relatively short capillary separation columns operated with high carrier-gas flow rates and fast temperature programming. Unique features of TOFMS include high spectral acquisition rates and spectral continuity (constant ion-abundance ratios across chromatographic peak profile).

This article will examine the uses of thujone and thujone containing materials in perfumery, and describe some synthetic materials — old and new— that are intended to provide this note.
