If anyone wants to know about hydrocarbons, please email/text/call me. 99.999% pure n-butane is a pipe dream. It doesn’t exist period. Anyone who claims it does doesn’t know what they are talking/posting about.
How did you like that reality?

THC - you wrote about sourcing crude. Was just trying to help by providing the standard for first run butane.
Man, this thread is a ride…
Just adding my 2-cents. Since Cortland is the only company within arms reach, and easily accessible to this region (certainly a problem).
Every time I distill I notice some faint/foul odor, and it drives me f***ing bonkers, and requires me to go through most of the components the gas from the tank comes into contact with. I have even re-distilled solvents and still picked up a minor odor. Now I ain’t no fancy pants big city chemist, but butane and propane usually have to have odors added so people can detect smells more easily…
So this has me scratching my head, because I have noticed an influx of articles on the forum regarding foul smelling/tasting concentrates, and yeah, starting material has a lot to do with things, and I have no doubt that CRC does alter profiles… but wouldn’t unscrupulous gas be more suspect? Its a variable that would make it a consistent issue for everybody effected… meanwhile, everyone plays with variability elsewhere CRC packing, input material, etc…
(Not pointing fingers, this is a good discussion on the efficacy of solvents. This isn’t a bad discussion)
The only reason this conversation sucks is because it is serious in nature and the responsible conversation to have, like talking to your parents about sex. We need a better description than… ya know… 
So now I wanna do a better control experiment…
I may order some gas from elsewhere, my inner scientist says to experiment, I also have to redistill gas soon, so if I find anything that makes me scratch my skull, will report back here.

So after distillation of this last batch…
Not nearly the notable smells I have gotten in the past.
Seems pretty mute over all, nothing that really “keys” me off to much haberdashery, but still a 
moment…
But a nose is only so good at detecting things, and only so scientific.
The tank.
Filter paper I ran solvent through.
And the honey pot after distillation (note, it is possible that some of the remnants are leftover oils from processing yesterday.) I cleaned with alcohol, and let evaporate, and there is definitely an odor there I can’t place my finger on.
The short and skinny… definitely had a smell to the contents of the honey pot, however not nearly as odorous as I have dealt with in the past from Cortland. I also didn’t distill a 20-30lbs like my norm, this run I added 16lbs to my solvent tank.
The rag I used is def a little stinky afterwards, and warrants some worry.
Just my 2 cents.

@Tech1145 I appreciate your semantic breakdown of this thread. At very least it lays bare the fact that @thc_gas isn’t doing themselves favors by having such an inexperienced individual (gender regardless) as their PR go-to. Digressing into ad hominem rhetoric or collapsing into victim mode or emotional appeal is definitely uncalled for.
I can only speak from personal experience and the empirically compiled datasets garnered from repeat purchase scenarios. Neither the 70/30 we got 1600# nor the Ntane we’ve gotten 3000# of from THC has been bad at all. I agree with @TheGooMan that there are numerous other variables with each individual run to be considered as potential contaminants in the equation.
In the name of science and further investigation, I’m gonna buy 200# from Oxarc on Tuesday, take samples from their tanks as well as our existing Cortland stock and send to a qualified third party lab to be tested on my dime. Then we’ll have more than one COA to reference, which is how statistics and unbiased research should work.
White Knight or Witch Hunt, choose your own adventure and hope you’ve got comprehensive awareness of all the nuanced variables in context. If there’s a difference in quantifiable quality between the two gas companies, that’s all that matters. Otherwise you’re just superficial brand-loyal at the end of the day. Cheers.

@YourMomGoesToCollege absolutely! We need quantifiable results! I know a smelly rag is qualitative, and I will be very curious to see your results!

I also think it is important that extractors question what it is they’re using. I wanna know whether or not the people are trying for the efficacy standards that I want to hold myself to as well.
If I am not doing my job right because of some extrinsic factors on the quality of necessary materials, then I am not doing my job right… and that, is a problem…
So, this discussion is great to know… because if I am not sourcing the best possible materials I can, then that’s a problem to me, and will adjust the variables as needed.
Now, on a softer note… look at the happy little turtle. ,=,e

Thank you for this.
Oxarc/Apis and other trusted suppliers provide hydrocarbons that have been MANUFACTURED!!! for the extraction market. Not cheap, unprocessed gas directly from feedstock full of terrible shit. These products are for human consumption, so the butane/propane/iso has been processed and quality checked to a pharma level. I know. As a buyer you must demand to know the source of your supplier’s gas.

99.99% n-butane and 99.999% propane exist, but not 99.999% n-butane.

If your supplier is not cleaning the cylinder before every refill there is no possible way for them to verify the purity of its contents. The variability of the potential contaminates is frightening and this practice of topping off tanks is going to be banned very soon. We have trucks running 24/7 in Samoa and would love to help you out.
We certify our 3 phase cylinder decontamination before every refill with COD’s that are necessary to prove purity combined with COA’s. By cleaning every cylinder before every refill, you can rest assured there will be no variable contaminates, toxic benzene accumulations or dangerous pressures resulting from chlorine contamination.
As the highest volume supplier in the extraction industry our 2021 pricing is more competitive than other suppliers selling cylinders that are just topped off and never cleaned. Even better, this month we are paying $100 per LP239 cylinder sold for every new customer referral brought to us by anyone!
Shoot our supply team a call or text anytime at 1-833-Pure-Gas or 1-833-787-3427 to get set up:pray:

Did you get results? We are doing a white paper on cylinder contamination if “clean” gas. Would love to collaborate.
You should do a white paper on why your own gas causes instant crashes. Spend 20k a month w u and get no answers? You should be putting your considerable profits into making sure your actually selling what u say you are. Who cares if u clean the cylinders if you don’t know what’s in them. Perfect time for a new gas supplier to come up.
Anyone know if airgas sources gas through air liquide or GI?
