Using E-PAK technology to remove chlorophyll in a biomass sample

> back to Application Notes

The following study demonstrates the efficiency of E-PAK activated carbon cartridges to remove chlorophyll and other impurities from a biomass sample. Cannabis was herein chosen as the model sample.

The variables analyzed after a pre-purification step were:

• Recovery of cannabinoids (CBD);
• The signal level of the chlorophyll by UV-visible spectroscopy (qualitative test);
• The saturation of the E-PAK cartridge.
