CBD Separation

Cannabis extracts must be pre-treated before purification of CBD, as they contain many impurities from the plant itself, such as waxes or colors. As CBD is required in a highly purified form to maximize its pharmaceutical effect, all other cannabinoids (over 100) must then be removed from the final product. Due to strict acceptable limits set by countries around the world, removal of Tetrahydrocannabinol (THC) from the final CBD product is a key step in production.

When compared to silica-based alternatives, our Chromalite® chromatographic resins offer a simple, high performance and cost-efficient method to separate THC from CBD, thus maximizing the purity of your CBD extracts.
