Look at the product of reaction. This still produces elemental S.
This is the one that still further causes troubles here.

Oh, fellas…
2 things here. Paraffin and mole sieve beads

Not directly the copper, but rather the S bearing precipitate that you form on the surface.
You simply sort of regenarate a part of you reactant in situ, or an analogue.
At room temp it is not problem, but at higher temperature…
You still have solid S that will be dragged with the solvent cannabinoid mixture.
While it is the least mobile specie once in a vapor… but will still react.
The idea would be to heat the material, promote sulfure reduction and vaporization, trap it as close as possible from the emiting point. Then once it has gone from the flask (need an excess reageant), remove that trap before the vapors of interest goes through. Something like that.

Sixth wave type polymer tech would probably do the job with the proper polymer beads.

S is easier to remove then h2s IMO
H2S co distills because it messes with vacuum
I can seperate S out with copper flakes

Scanned this as well… https://res.mdpi.com/d_attachment/catalysts/catalysts-10-00521/article_deploy/catalysts-10-00521.pdf
Worth a dive into. I’ll dig deeper later. Have to help my son with 6th grade science.
Can’t get away from this shot even if I tried:rofl:

Elemental sulfur will solidify which means filtering is a good possibility.
I’m still going with copper flaked filter bed with AC and betonite and packing mol sieve beads held back with copper scrubbies in the head as an experiment.
Now… to find a place to test for left over sulfur🤔

@kcalabs can you guys test for sulfur and more specifically elemental sulfur?

Copper wool in solution at room temp for a couple days, rotovap, and redistill with copper wool packed head?

I’d rather go with flakes so I can perform a high stirring at room temp, then filter it out with a bed of AC and betonite.
I’ll throw everything I got at this b*tch to clean it up. Filtration, LLE, along with packed distillation heads.
10a -13a angstrom seems to be the sweet spot for elemental sulfur according to what I linked above.

It seems like wool suspended above the bottom of the vessel would work better than flakes on the bottom, but that’s just a guess🤷♂️
Edit:when it comes to stirring

Oh, agreed…
I mean the flakes in the reaction after it’s cooled down so you can whip it fast for surface area contact
Once the hydrogen sulfide is gassed out, anything left will be in the solution

Unfortunately, no. We can perform elemental analysis on the ICP-MS, but sulfur is part of CHNOS testing requiring different instrumentation than what we have in house.

Thank you for the reply, do you have a recommendation on a lab that can?

It looks like Galbraith has the capability.

Thanks so much for the suggestion, their range of service is great!

Come on…
Can’t ya just fire up a sample and pass it around and give your results on that alone?
That’s how Reddit does it🤷🏼♂️

Haha, we can put it on there and tell you if there is sulfur present, but no way to quantify.

So you can at least tell us a solid yes or no if there is sulfur present?
