Volatile Analysis

Volatile analysis refers to the laboratory measurement and identification of aromatic compounds (terpenes, esters, and other volatile organic compounds) present in cannabis plant material. Breeders and researchers use gas chromatography (GC) and related analytical techniques to profile the chemical composition of different strains and phenotypes. This data helps document lineage characteristics, track consistency across generations, and understand how environmental factors influence terpene expression. Volatile profiling has become a standard tool in breeding programs working to stabilize or enhance specific aroma signatures. The results are often reported as relative percentages of major compounds rather than absolute concentrations, reflecting the complexity of cannabis biochemistry.

Breeders use volatile analysis to identify phenotypic markers, select parents for desired terpene profiles, and verify genetic stability across seed generations. Accurate profiling helps distinguish between closely related cultivars and document the biochemical expression of novel crosses.
