you could potentially fractionate the terpenoids from the cannabinoids but it would be difficult. fractionating the individual cannabinoids with co2 is possible as well but requires special equipment and a lengthy development process. The technique (on a larger scale than just analysis equipment) would be SCF column chromatography. Would be a pain in the arse, what i think GW does and others have eluded to it here: they grow a strain which produces the desired cannabinoid ratio or they blend materials accordingly then extract directly from the material which had the correct ratio to begin with. This way they dont need to focus on the fractionation/ blending of individual cannabinoid fractions.
as far as i can tell they do extract equally as well ( cbd and thc) with co2
need to get going on some analysis hopefully in the new year.
Im running my vape at 375 f still has worked good so far.
runs best with a dollup of extract of course
