Quantifying Terpenes in Hydrodistilled Cannabis sativa Essential Oil with GC-MS
April 21st 2025A recent study conducted at the University of Georgia, (Athens, Georgia) presented a validated method for quantifying 18 terpenes in Cannabis sativa essential oil, extracted via hydrodistillation. The method, utilizing gas chromatography–mass spectrometry (GC–MS) with selected ion monitoring (SIM), includes using internal standards (n-tridecane and octadecane) for accurate analysis, with key validation parameters—such as specificity, accuracy, precision, and detection limits—thoroughly assessed. LCGC International spoke to Noelle Joy of the University of Georgia, corresponding author of this paper discussing the method, about its creation and benefits it offers the analytical community.
