Volatile Analysis

Volatile analysis refers to the laboratory examination and identification of aromatic compounds in cannabis plant material, primarily terpenes and other small-molecule volatiles. This analytical approach uses gas chromatography, mass spectrometry, or similar techniques to quantify and classify the chemical profile that contributes to a strain's distinctive scent. Volatile profiling has become increasingly relevant in breeding programs seeking to stabilize or enhance specific aromatic characteristics across generations. Understanding volatile composition helps breeders make informed decisions about parent selection and trait inheritance. The volatility of these compounds—meaning their tendency to evaporate at room temperature—makes consistent testing and preservation methodology important considerations in seed storage and phenotype documentation.

Breeders use volatile analysis to objectively evaluate and compare aromatic phenotypes, reducing reliance on subjective smell descriptions. This data helps guide crosses aimed at specific terpene profiles and supports documentation of stable traits within breeding lines.
