SPD for THC remediation vs. chromatography?

Hello All,

We are looking into THC remediation and have mainly been reading about chromatography systems. However we have seen a couple people using short-paths for this, and I’m wondering what the pros/cons are of it versus chromatography.

Thanks!

Lol nope, if you can figure out how to fractionate THC from CBD in distillation you will revolutionize the industry

“Spinning band distillation systems are great for fractionation of cannabinoids. The technique uses the same methodology as classic glass Short Path Distillation units, which is how many of the technicians in the hemp industry started out or are currently running their laboratories. Individual cannabinoids can be separated by temperature, reducing the use of solvent, resins, additional instrumentation (as standard distillations can be carried out on these instruments as well), and 3rd party interactions for toll THC removal services.”

Yeah it doesn’t work well in completely separating, it’s for partial fractioning not full remediation.

Doubtful. The spinning band manufacturers BR will tell you they can’t do it.

Has anyone tried using a vacuum controller to maximize the temp difference between the cannabinoids boiling point? Normally we try to achieve the lowest ultimate vacuum when distilling but since the boiling points of thc and cbd get closer the deeper the vacuum gets has anyone tried using a vacuum controller to keep the vacuum level at like 350 microns through heads and the first 10% of mains, then switch flasks and let the vacuum drop as low as you can get it for the remainder of the mains? You’d have to slowly ramp temp through the first part of mains before you try to pull ultimate vacuum. I’m short some equipment to try this as I don’t have a vacuum controller or much time to experiment but it’s a thought I’ve been mulling over for a while.

Makes me wonder if anyone’s distilled at ambient pressure before and if they got any distillate out of it.

Have you ever taken a dab and collected the reclaim throughout the rig?

@MagisterChemist Yes it’s called hitting a dab. All that reclaim? Practically distillate.

I know @downtheterphole and I talked about modding a volcano vaporizer to distill cannabinpids

The problem is severe degredation of the resulting atmospheric distillate. Have you ever taken a hit of that stuff? Shit fucks you up in all sorts of ways

Google “pressure swing distillation”

It’s used to break azeotropes- I’ve played with manipulating compression in a still through adding multiple short condensers in between collection flask swing arms and gotten some neat results through pressure swings.

No I usually make edibles with it or put it in my crude lol

What if the entire atmosphere of the “room” or just a small little distillation workplace was filled with inert gas :thinking:

I guess this could be achieved in a cls

I bet the Egyptians had some fire cbn

Ok lol yes. Of course you can distill it (vaporizers do the same thing). I meant more like, has anyone ran a standard distillation SOP (slow ramp, collecting fractions) at ambient pressure.

You could probably manage the degradation of the compounds and distill at a higher vac level if you could set up a nitrogen backfill during distillation that worked in coordination with your vacuum controller. Basically start the distillation under a nitrogen sweep? :man_shrugging:t2:

Presence of oxygen is not the only factor in degradation tho

And you’d have to heat the nitrogen otherwise you’re just strugglefucking that oil to death

Seems doable with a heat exchanger on the nitrogen infeed.
