Chromatography-Primarily based Strategies (HPLC, GC)
Chromatography-based strategies are generally employed to investigate and quantify THC concentrations in numerous matrices. These methods contain separating and figuring out compounds primarily based on their bodily and chemical properties.
Excessive-Efficiency Liquid Chromatography (HPLC)
HPLC makes use of a liquid cell section to separate compounds in a pattern. The pattern is injected right into a column full of a stationary section that interacts with the analytes, inflicting them to elute at completely different charges. The elution of THC and different cannabinoids is detected utilizing a UV-Vis detector, which measures absorbance at particular wavelengths.
Fuel Chromatography (GC)
GC is a way that separates compounds primarily based on their volatility and affinity for a stationary section. The pattern is vaporized and injected right into a column full of a stationary section. Because the vaporized pattern passes by means of the column, the completely different parts are separated primarily based on their boiling factors. THC and different cannabinoids are detected utilizing a flame ionization detector (FID), which measures the ionization of the compounds as they elute from the column.
| Technique | Benefits | Disadvantages |
|---|---|---|
| HPLC | – Excessive decision and sensitivity – Appropriate for complicated samples – Can present quantitative and qualitative info |
– Requires specialised tools and experience – Could be time-consuming |
| GC | – Quick and environment friendly – Can analyze risky compounds – Comparatively cheap |

Spectroscopic Strategies (UV/Vis, FTIR)
Spectroscopic methods make use of the interplay of electromagnetic radiation with molecules to supply details about their construction and composition. Within the context of THC evaluation, two main spectroscopic methods are generally used:
UV/Vis Spectroscopy
UV/Vis spectroscopy measures the absorption of ultraviolet and visual mild by molecules. THC reveals absorption peaks at particular wavelengths, which can be utilized to quantify its focus. This system is comparatively easy and cheap, making it a typical selection for THC testing.
FTIR Spectroscopy
FTIR (Fourier rework infrared) spectroscopy analyzes the absorption of infrared radiation by molecules. Useful teams current in THC, such because the hydroxyl and carbonyl teams, produce attribute absorption bands. By measuring the depth of those bands, FTIR spectroscopy can present each qualitative and quantitative details about THC.
Widespread Absorption Bands for THC
The next desk lists widespread absorption bands related to THC and their corresponding practical teams:
