What is HPLC?

HPLC is a laboratory technique used to separate, identify, and quantify compounds in a mixture. It works by passing a liquid sample through a column filled with a stationary phase under high pressure. The different components in the sample interact with the stationary phase and are separated based on their chemical properties.

In the cannabinoid industry, HPLC is used to isolate CBD and other cannabinoids with high accuracy. This process is essential for creating pure products, analyzing potency, and removing unwanted compounds like THC.

   The mobile phase is a liquid solvent that carries the sample through the system. In cannabinoid applications, common solvents include water, methanol, or acetonitrile.
2. Stationary Phase
   The stationary phase is a material inside the column that interacts with the sample. For cannabinoids, silica-based materials are commonly used.
3. Detector
   A detector measures the separated compounds as they exit the column. UV-Vis detectors and mass spectrometers are popular choices for cannabinoid analysis.

The sample is injected into the system, and as it moves through the column, each compound separates based on its interaction with the stationary phase. The detector then identifies and quantifies each component.
