Decarb with a catalyst!
You can get some separation of C and T this way too!
(more so a heavier concentration of the T to the first fractions)
all of the oil will contain T but the second fraction is often below .3T if you dial the travel time and temp and solvent ratio right
so you have some compliant full spec crude to play with that has more of an intact terp profile Right off the bat
So running your ethanol or methanol diluted oil through a column of activated alumina, decarboxylates the oils at different rates- the T decarbs more rapidly than the C so it moves through the column faster and elutes first
This catalytic decarb also lowers the temp for decarb significantly, so there’s no reason not to just add the stuff to your decarb pot and apply less heat to your cannabinoids while also pulling water soluble junk and other alumina friendly unwanteds, the stuff is cheap as heck too
