Who is your LN2 supplier?

Breh, I just saw your gas on Instagram not in a positive light… the post was reported too lol

You should be able to specify what grade of LN2 you want. Other option would be to get a nitrogen generator but you’d have the upfront cost and you’d prolly need a dedicated oil-less air compressor, drier and filter.
About $20-25k new all in
we have 2 huge rotary screw compressors so this might be a viable option. We do specify grade we just have hard time getting matching coa’s to the lot numbers of tanks. We see coa’s all the time altho most of them look less official then me writing myself a check for a billion dollars. We just want to work with a company that’s focus is chain of custody and providing what they say. Altho going forward we will be checking for ourselves regularly.

Do you have in-house analytics?
A setup can be had for not too much (I think) to sample gases—beyond my previous experience but obviously it exists.
Just a thought—I have also had a ton of weird, seemingly bullshit CoAs for gases and solvents

they sell tanks look at the web page.
they advertise 24lb and 120lb cylinders.
honestly the shit I am seeing in this thread the risk is too high.
as phil said bullshit coa’s exist its spoken about all the time here.
id be putting the cost on top and again advertising that your
using it.
then I would be sueing every fucker that gave me anything
that had unacceptable impurities.
this stuff should all be food grade.
and then the comment on how to distill the funk out of your
solvent when its new just gives me nightmares thinking about it.
your add for your own carts on line could go like this.
is made with pure ingredients.
is it made with puretane.
but for sure they sell in volume.
plus you can plug im using the only usa made gas and our
product (well oil anyway) is made with 100% us ingredients
and then you could sit on your mountain and shit on everyone
else explaining whats going on in this thread and showing
the lovely pics that are here.
its a legal nightmare and an advertises dream.
Why do you think I tell ppl to always distill? I’ve dealt with dirty gas myself before and adopted best practices for a reason. Our stuff isn’t testing hot for benzene and we source our gas from HPG currently. And I know the person who posted it personally and have no reason to report the post lol.

Same issue here, for about a month, all started when we introduced a fresh can, after a month of thinking it was every other problem and spending countless hours researching (sprays, vacuum oil, crc, you name it) we, like you - didn’t think it was in the cylinder… as you said it’s not our job to expect the gas supplier to be failing us…
bummer- can’t get that time back; getting paid by what we produce has left us digging into savings just to get by.
**Does anyone have a solution for remediating shatter effected by this?
Or a sop to cleaning contamination in system?
a cheap way to get some eyes on your solvent
raman spectra for common solvents.
raman is easier and cheaper than other forms of spectrography.
just point the thing at the solvent and shoot in some cases depending on the
device you use.
I still think if you find you have crud in your food grade solvent that its a matter for the
courts to fix and no distilling at all should be done on the solvent.
I would even go as far to say even with my past that if its going to be sold for human
consumption anyone who finds solvent like this and then distills and does not get
a food grade cert on there solvent before using it should also be a case for the courts
to solve.
really ?
In house distilling of bad products is as bad as going to the chemical recycler
and reusing industrial waist.
its good or its not.
I know we all get it tested blah blah.
the gas guy above put it perfectly.
profits vs giving a …
people smoke a lot of this stuff and that makes it even the more worse as there is no
liver or kidney to filter.
this may not work so well for checking non branched alkanes against each other
though to some extent it would.
raman works on the generation of light frequencies due to the electrons
in a functional group letting out light when excited with a single frequency.
each different functional group gives its own areas on the spectrum
so the benzene would have been piss easy to tell from 3 methyl heptane.
and 3 methyl heptane would be easy to tell from heptane.
but heptane and hexane not so easy as they are both alkanes with the same functional
groups.
there would be a little difference but I would not want to try and read it if there was a mixture of straight chain alkanes.
raman for sure will tell metallic/ionic impurities from solvent/covalent too.

Maybe I missed it, but has any company posted a coa?
Scroll up to post #98 in this thread. This is probably the most important conversation on butane extraction ever had and we are seeing a lot of members defending dangerous and unethical supply standards on this thread right now.
This is a very important conversation. Let’s stop sweeping toxic “mystery” oil contamination under the rug and PREVENT IT with good practices.
A low purity supplier called us out for lying about our purity standards and we immediately posted recent COA’s and COD’s above. We then challenged the above low purity supplier to post their COA and we got crickets.
We are the only supplier in the industry with signed and sealed COD’s to trace our 3 Phase Cylinder Decontamination performed on every cylinder, before every refill to prevent toxic mystery oil accumulations.
These COD’s match the DOT serial numbers on our COA’s so you can prove a clean chain of custody and not waste time and money distilling toxic oils and contaminates out of your gas.
Further, extractors defending the use of low purity gas and toxic mystery oils are up above getting keyboard tough with claims cylinder cleaning is unnecessary despite precedent in FDA CFR 211.8-211.94.
Would you eat “clean” food off dirty dishes in a restaraunt if the coa said the food was clean?
We would love to test your cylinders and work with you to improve your process. We have a great relationship with Amspec and Eurofins.
We also have clients that are required to independently verify purity standards of all active ingredients before running and these are our go to testing labs.
Call us.
Post the coffee cup again!

Sorry for caring. Is this better…?

I was definitely told there’s no need to distill when I asked about their decontamination process in the past. I still have the email.

I will post the email if they request me to do so, or if they try to deny it in any way. I’ve been biting my tongue on this one as I didn’t want this to become another SD hate thread, but it’s annoying to say the least when they start talking about sweeping shit under the rug.
