SPE – Solid Phase Extraction for Cannabis Sample Prep

Remove fatty matrix interferences before analytical analysis

The oily nature of cannabis plant extracts makes it more difficult to test for contaminants and compounds such as THC, CBD, and other cannabinoids. The use of SPE sample prep permits the removal of interfering matrices that would otherwise compromise results or damage downstream analytical instruments.

SPE can effectively remove most of the fatty matrix interferences and some of the darker pigment colors that affect UV transparency. Solid-phase extraction is also automation-friendly and can facilitate the automation of sample cleanup for filtrates in Cannabis.
