Spectroscopy Methods

Spectroscopy methods represent analytical techniques used to identify and quantify volatile organic compounds (VOCs) in cannabis. Gas chromatography-mass spectrometry (GC-MS) and liquid chromatography remain standard laboratory approaches for mapping terpene profiles, cannabinoid concentrations, and other chemical constituents. These methods provide objective, reproducible data independent of human sensory perception. Spectroscopic analysis has become foundational to modern cannabis breeding, allowing cultivators and geneticists to document chemical consistency across generations and identify genetic markers linked to specific aromatic profiles. Understanding these analytical frameworks helps breeders make informed selection decisions based on measurable chemical traits rather than subjective evaluation alone.

Breeders employ spectroscopy data to track chemical stability across seed lines, verify strain authenticity, and identify parental plants with desirable volatile profiles for targeted crosses. This objective documentation supports lineage integrity and helps establish reproducible genetic standards within breeding programs.
