New regulations in US require all hemp products to be free of THC. Any ideas for removing this from an ethanol extract of hemp? Meg Raj

IN SPE a mixture of Hexane /ethyl acetate and acetone 50:40:10 is used to elute THC from a silica surface. For any would be "pot heads" this would be quite toxic!

thanks for the quick response mkane. Some of my hemp products are for food and tonics so need to remove the THC without leaving toxic residues.
