Liquid Chromatography Mass Spectrometry Lc Ms

Liquid Chromatography Mass Spectrometry (LC-MS) is an analytical technique used to identify and quantify cannabinoids, terpenes, and other plant compounds in cannabis samples. The method separates chemical components through liquid chromatography, then ionizes and measures them by mass spectrometry, providing precise molecular weight and structural data. LC-MS is widely adopted in cannabis testing labs and breeding research to verify cannabinoid ratios, detect contaminants, and confirm strain authenticity. Unlike simpler chromatography methods, LC-MS offers high sensitivity and specificity, making it the reference standard for many regulatory compliance programs. Breeders and researchers use LC-MS data to document genetic stability and chemical consistency across generations.

Breeders rely on LC-MS results to validate claimed cannabinoid profiles, track terpene expression across crosses, and ensure seed-to-plant chemical consistency. This data is essential for documenting strain lineage and establishing breeding standards within cultivar families.
