Chromatography Analysis

Chromatography analysis is a laboratory technique used to separate and identify volatile organic compounds (VOCs) in cannabis plant material. Gas chromatography (GC) and liquid chromatography (LC) methods isolate individual terpenes, cannabinoids, and other chemical constituents, providing quantitative data on aroma profiles. This analytical approach differs from sensory evaluation, offering reproducible, objective measurements of chemical composition. Breeders and researchers use chromatography results to document strain lineages, verify genetic stability, and map how cultivar crosses inherit specific terpene ratios. Understanding chromatography data helps distinguish between similar-smelling strains with different underlying chemistry.

Breeders employ chromatography data to select parent plants with target terpene profiles and to track how chemical composition segregates across generations. Detailed chromatographic fingerprints become part of a strain's documented lineage record, enabling reproducibility and informed crossing decisions.
