SPE – Solid Phase Extraction for Cannabis Sample Prep

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.

CHROMABOND vacuum manifolds permit simultaneous preparation of 12, 16, or 24 samples. There are three different configurations to hold up to 12, 16, or 24 CHROMABOND columns or CHROMAFIX® cartridge.

The manifolds consist of a rectangular glass cabinet with a vacuum gauge and a polypropylene lid which hold the columns or cartridges.

With the control valve, the vacuum in the chamber can be adjusted and read from the gauge.

The replaceable valves/stop cocks on the lid allow individual vacuum control for each solid-phase extraction column if required.

The cabinet is fitted with a variable rack with exchangeable partitions, which accept a wide variety of vessels like test tubes, measuring flasks, scintillation vials, autosampler vials, plastic vials, and many more.
