I like this one:
@SidViscous is correct, as run, most are not doing chromatography. But chromatography tells you in its very name that it is about separating out color…and used correctly we can separate cannabinoids using chromatography. So working up chromatography in our extraction solvent IS a valid route to pursue imo.
You can’t let the CO2 guys have all the fun
