What it is / How it shows up:
HPLC, or High-Performance Liquid Chromatography, is a common technique found in cannabis Certificates of Analysis and lab reports. It helps in determining the concentration of various cannabinoids, such as THC and CBD, ensuring that products meet quality standards. This method involves separating components through a liquid medium, which moves through a column filled with a solid adsorbent material. As different components travel at different speeds, they are detected and quantified, providing accurate data on the chemical makeup of the cannabis product. Consumers may see HPLC results as part of a product’s lab testing to ensure safety and compliance.
How it’s measured or identified:
- Uses a liquid solvent as the mobile phase.
- Involves a column with a solid adsorbent material.
- Retention time helps identify different components.
- UV detectors are often used for detecting compounds.
Use in context:
- HPLC results indicated a high concentration of CBD in the tested sample.
- Lab reports often mention HPLC for cannabinoid profiling.
- Producers rely on HPLC to ensure consistency in product potency.
Safety & compliance in Canada:
- HPLC testing is critical for regulatory compliance and consumer safety.
- Licensed producers must ensure accurate HPLC testing for product labelling.
- Compliance with Health Canada standards requires validated HPLC methods.
