This article introduces the characterization of lavender oil using Agilent J&W DB-1ms Ultra Inert capillary GC columns. Gas phase analytical techniques including GC/MS, GC x GC, and GC/TOF were used to analyze the main components in lavender oil samples from several suppliers. The well-resolved components were then identified using a single quad GC/MS versus NIST Library 5.01, and the identified peaks served as the fingerprint for analysis. The same separation using GC-FID could be used to evaluate subsequent samples quickly and cost effectively. The well-resolved, sharp peaks observed on the Agilent J&W DB-1ms Ultra Inert column made this approach possible.
This document describes an application using Agilent J&W DB-1ms Ultra Inert capillary GC columns to characterize lavender oil samples from different suppliers. The study utilizes gas chromatography coupled with mass spectrometry (GC-MS) and flame ionization detection (GC-FID) to identify and quantify major components in the essential oil.
