Chromatographic Testing

Chromatographic testing refers to laboratory analytical methods used to separate and identify volatile organic compounds (VOCs) in cannabis plant material. Gas chromatography (GC) and liquid chromatography (LC) are common techniques that break down aromatic profiles into measurable component peaks, revealing terpene concentrations and presence of residual solvents or contaminants. These methods produce quantitative data rather than subjective aroma descriptors, making them reproducible across different testing facilities. Breeders and researchers use chromatographic profiles to fingerprint strain genetics and verify consistency across harvests. Results typically display terpene percentages and compound identity, providing objective chemical records distinct from sensory evaluation alone.

Breeders working in controlled genetics programs use chromatographic profiles to select parent plants with desired terpene ratios and verify that crosses maintain target aromatic signatures across generations. Detailed chromatographic data helps distinguish between phenotypic expressions of the same genotype and confirms whether breeding goals for specific aromatic compounds have been achieved.
