Terpene Analysis Methodology

Terpene analysis methodology encompasses the laboratory techniques used to identify and quantify volatile and semi-volatile compounds in cannabis plant material. Common analytical approaches include gas chromatography-mass spectrometry (GC-MS), liquid chromatography-mass spectrometry (LC-MS), and headspace analysis, each with different detection capabilities and accuracy thresholds. These methodologies vary in their ability to detect minor terpenes, thermal degradation products, and oxidized compounds, which can significantly affect reported terpene profiles. Standardization remains inconsistent across laboratories, leading to variation in how the same genetic sample may be reported. Understanding the methodology behind a terpene profile is critical for breeders evaluating genetic stability and for seed developers selecting for specific aromatic or volatile compound expressions.

Breeders rely on consistent terpene analysis to track aromatic trait inheritance across generations and to identify phenotypic variation within a genetic line. Selecting the same analytical methodology across breeding cycles helps establish reliable baseline data for targeted trait stabilization and parent selection.
