they are “still waiting on the standard” (multiple labs) 
man, I hope they figure this shit out…
Waitwat?
How are they testing if they don’t have a standard?
Demand MS verification if false positives persist.

yeah this is a red flag large enough that i would never send a sample to this lab again. you cannot quantify anything without a standard. the fact that someone said 90 ppm and also said they don’t have a standard is inexcusably problematic

@EverettMarm I think it’s because vitamin e acetate testing isn’t required by the state until October technically, so they are kinda just doing this test on the side for “practice/prep” for lack of a better word.
They didn’t fail us, or even put it on the COA. Just told us on the side that there were high levels of vitamin e acetate and that it would fail if the test was required. They are saying once they get the standard they will be able to better identify exactly what it is. It’s definitely concerning though, especially given the past issues we have seen.
So they just looked up the elution time from a similar sop and are definitively assigning peaks according to elution time alone without a standard.
That is beyond shady bullshit.
Is there even baseline resolution on the peak?
The fact that they issue a CoA that makes your product unsellable seems like actionable lawsuit material. Especially since there is zero actual proof in the form of a certified standard.
Run from this lab and never trust anything they do.

They aren’t making it unsellable. It’s basically an R&D test just for knowledge. It isn’t even on the COA. they just called us and told us they saw a peak in the same window vitamin e acetate should be, and come October, this stuff would fail.
Sounds like the aren’t equipped to be definitively saying it’s vitamin e acetate, like you said, but they will supposedly have their standard by the time the test is required.
I sure fucking hope so.

To which you responded; “if you dumb motherfuckers fail me for vitamin e acetate based solely on published retention times, there will be consequences!”?
Or; “it appears you need my help figuring out how you’re wrong on this…call me when you’re actually equipped to perform that analysis…”?

Our chemist does most of the talking with the labs, as his knowledge of analytics is far better than mine. But yes, I know his response was something of that nature lol.
They assured him that they will be able to verify results once they get their standard. Fingers crossed I guess.

it’s a degradation product of chlorophyll iirc
I don’t think so
It does look like plant reuse the phytol for synthesis though…
phytol might’ve been what I was thinking about

Might have been.
…but this is cannabis.
A web search that included vitamin e was made from degraded chlorophyll could absolutely have gotten to
vitamin e acetate was (only) made from degraded chlorophyll during distillation
with ease on Reddit or Facebook.

curious what lab this was? We’ve just gotten some wonky lab results back as well. Feel free to DM me, if you care to disclose who it was?
Understood.
We aren’t even taking about coelution at this point without a standard much less a validated sop.
They can’t even say ‘in the same window’ without a standard. At best it is ‘in the expected window’. Which could mean, what +- a few seconds? But they don’t know exactly because THEY DONT HAVE A FUCKING STANDARD YET.
They will need to validate their SOP once they have the standard, and then they can definitively say it is or is not in the window.
Again, if you did the extraction, distillation, etc and know it should be clean always ask for an MS verification of the molecular ion and/or fragmentation pattern.

I’ll be sure to make sure we are asking for this any time we see questionable results… which is pretty damn often. thanks man!

I’m not saying you’ll be able to get it, depending on your lab, but a professional lab can easily do that for you if they are inclined.

I would confirm that is actually the limit, 0.5% makes a whole lot more sense.
you can use store/amazon bought vitamin e acetate thatll give you a RT
a standard is more necessary for actually quantifying

It’s all good until something in the matrix alters your retention time.
sure, but the same could happen with any CRM once you start screening various matrix types
The lab is just trying to get ahead of the game.
No excuse to make a customer worry for no reason, tocopherol standards are not hard to source and overnight shipping aint new lol
