This is exactly what I did to get a better idea of what was going on. Isolating 1 persons comments helped hone in on the actual process. Rather than everyone communicating back and forth about their individual process. Still tons of spoons in all different shapes and sizes littered throughout the entire thread…

B80 is getting packed down and prepped to be available for our distributors over the next 1-2 weeks. I’ll make sure the team posts it on IG. Should have some lenticular prototypes going out shortly but they all have a home for now.
Www.carbon-chemistry.com is the spot to find distributors and contact sales. I’ve been getting wrapped up in a beverage product dev and its eating my ability to respond to DMs

I don’t remember this being talked about earlier, I had some tests come back with 50-100 ppm acetone from not baking my powders(carbon chem) thoroughly enough, and had to repurge product which is annoying cause I’m not letting people smoke acetone. I doubt it’d leave enough to fail a test but really everyone should bake powders regardless, if you aren’t testing specifically for acetone then you definitely should bake them.
I dont have acetone in my facility and all the runs with fully baked powders were clean so I’m pretty sure it is the clays. Anyone else rsa test all their product and run into this before?

Wow, first time hearing about this! @Shadownaught , you got any insight?
@Griffin.Labs what solvents do you use to clean glassware and alike?

200 proof ethanol to clean all glassware and tools.

Do you recycle the etoh used for cleaning through distillation? I know that you said you don’t have acetone in the lab, but is there a chance there was any in the past? 50-100 ppm is noteable, it’s got to be comeing from somewhere. The source of contamination has me scratching my head, Do you know if acetone is used in the washing the powders at the manufacturer?
In my mind the source could be the stationary phase powders, recycled solvent, some fluke at the testing lab, or an “employee” that is unknowingly useing it or had brought it to your faclility.
I’ll be curious to see how this pans out…
Yeah my guess is it was the powder because of the samples it happened to, it was 4-5 that didnt get baked or only got baked for 3-4 hours. We use the ethanol and waste it ou andt we don’t extract with it or do any distilling at my lab. Theres nothing else I can think of, i distill my gas and its always extremely clean, never had acetone there, been running over a year.
That was my guess as to where the contamination came from too @Soxhlet The manufacturer washing the powders, hopefully shadow can chime in. it came back at zero ppm butane and propane so it could of been higher before the original purge too.

Acetone is not involved in any of the manufacturing process and we don’t use acetone in the warehouse filling department. Thats pretty interesting, did you see any similar results from dried powder runs?
Where do you get your ethanol from?

Thanks @Shadownaught, i guess that answers that question,That was the only time I’ve seen acetone pop up, all the other 100s of crc runs I havent seen it, but i always bake the powders. Ill look up the ethanol supplier but its labeled 200 proof anhydrous ethanol, I gotta dig deeper and see where other sources of contamination could be. i guess I Will update again if I figure anything out!.

Acetone can be an azeotrope with ethanol and in the right conditions can be made from dehydrogenated and oxidized ethanol.
“consistent with the generation of acetone from ethanol by ketonization of carboxylates which are obtained by dehydrogenation of this alcohol followed by oxidation.”
But that would normally require a catalyst. Kinda stumped man, never seen acetone results due to absorbents before 
If you find the source let me know.

Actetone is naturally present in cannabis.
I’ve had it pop up in tests for ages. Freaked out the first couple times and I never had it in my facility.
And far before I was using media

@Dred_pirate That makes me feel better, someone told me that one of the sprays they use can mix with butane and create acetone i thought it was bs but maybe its more of something like what you’re saying. I’ll keep looking for sources of contamination and the like and will update it i find anything. I test everything and have done 100s of crc runs so theres a really good chance its not the adsorbents, but that would have been nice to have it figured out.

Medcropper was the first one to let me know about it.
I used to be "mis"informed and thought terpenes degraded into acetone, but we’re just doing what our titles entail. Concentrating it, and it’s now at a detectable level

What’s up with the opaline silica are you guys getting any soon or no?
Trying this method First run did a small test ran 50g of each per # now getting darker not consistent color also noticing the silica is not changing color much I have tried stalling and soaking for l ok longer still darker results any help would be appreciated
Is it silica stacked directly on top the t5. No plates BTW?
T5 on bottom magnesol silica60 on top with retention ring three filter stacks with plates and rings on bottom of crc
I feel like I’m getting channeling because of not much color change to silica or magnesol I have tried very slowly filling crc even soaking or stalling in crc for periods of time
