I can’t wait for us to figure out. The exact cause. Class action lawsuit Forsure. I wonder how many 10s of millions have been lost because of this.

Our lab is clean not dusty

Clean like grey rooms or even cleanrooms ? 
I’m not implying extreme dirt with my comment. I believe it could be barely noticeable, even hard to detect.

Well no noticeable dust. But without an actual clean room I would guess there some level of particulate in the air but I don’t notice it.

That’s how you read that? It’s like you’re trying to fuck up understanding,

Who is water washing cannabis they’re about to extract with butane? Your suggestion should have more bearing on what’s practical for extraction labs, Dr Moronnabis
No one.
No one is suggesting washing the cannabis biomass.
I take it you do not understand the “acid wash” step
in the preparation of THCA?

I haven’t been fast crashing long enough to say for sure that this wasn’t happening in the past, but if that’s the case then it’s definitely a different solvent mixed in there. It only happens when you crystallize around 50-65f. If you crystallize at higher temps, it won’t happen. That means it’s a co-solvent with a similar boiling point and by going hotter temps, you are pushing that solvent out or keeping it in the headspace. That’s why it makes sense that the 13x beads are cleaning the mystery solvent. If you do a Medusa crash, and move it into heat to try and salvage the big stone structures it created, you can see how it “frays” as it breaks down.

Reos we don’t do an acid step in bho extraction to thca. I believe you reference the acid step as that is what’s used to prep for hplc?

I know…but I’m not in charge down there!
however…the little CRC element you use at the end of the column
may suffice as a cation exchanger…I forget what you use.
No matter how you prepare your THCA when you redissolve in
the formic acid -acetonitrile mobile phase of the HPLC…
you are going to chromatograph the solute as THCA H form.
Because the mobile phase dissolves it and protonates the acid…
I will dM…you a paper to read…that exemplifies what I am talking about.

Even extracts made without CRC are doing this. Sorta puts the kibosh on that.

Once we got PCR working, it became impossible to NOT amplify some sequences in the pioneering labs.
The required DNA was literally EVERYWHERE.
So only so far fetched…

two different subjects…
if it is hydrogen peroxide (that is if and only if) a LLE type wash with water should solve the problem. Of course that is difficult for butane.
the second…“acid step” only assures protonation of the COOH group.
which is a different subject all together…but often in academic labs…
where you find chemists preparing cannabinoid acids to high purity
the process will include an acid wash step followed by water…to clean up. Followed by water purging step…sodium sulfate or magnesium sulfate (anhydrous)…assume you know what I’m talking about?

This would absolutely work with the timeframes…
we been doing this for YEARS, then this bullshit!
Which we’ve heard repeatedly.

I know what you mean about protonation but I don’t understand why you’re mentioning cation exchange in reference to… I think you mean peroxide formation?
Kinda seems like you’re trying to turn mole hill into a mountain when it seems like what you’re referring to may have already been ruled out.
I may also just be incorrectly interpreting your unusual text patterns.

Doubt it’s the case here, but lab contamination is an interesting thought

I’m not sure of your understanding of the “medussa stone”
problem? or “chalking”???
with reference to your understanding of the “protonation” of the carboxylic acid: yes you can do a LLE with like AcOH or HCl…
to ensure COOH form. But if you have an alkane solution You can also
pass it over a solid state cation exchanger like Dowex 50 in the H+
form…and the H+ of the resin will ensure protonation.
Now some CRC materials are acid washed …and end up acting like
ion exchange resins…my comment was something very specific to
what Johnbigoil has at the end of his extraction columns…so I was suggesting that such an exchange may be happening on his set up…
but I did not go into detail. This has nothing to do with hydrogen peroxide formation. Perhaps, you do not fully understand what I text.
To be clear: if you have hydrogen peroxide extracted from plant material
in your ALKANE solution, you should be able to remove it with a water
wash prior to your crystallization procedure.
The general properties of hydrocarbons are
- they contain only hydrogen and carbon and
- they are generally nonreactive except in the presence of chlorine and uv
This reaction uses chlorine based catalysts.
