I just cannot rap my head around the idea these have the same retention time on every column. Their structures are quite different, so we ought to be able to make a gradient/column combo that fully resolves then.

Does anyone think it would be ok to skip the filtering on silica if everything is filtered thru a 1 micron filter? As in the carbon t5 alumina ect. My plan is to warm scrub everything 60-90c 30 min ac t5 alumina. Either in a 5:1 etho mix or just in the oil after etho distilled then add etho to it 5:1 to filter. I heard etho and the bleaching agents don’t work as well and it’s better to use in just he oil or in a 1:1 heptane mix any help much appreciated. I imploded my sintered disc in my media filter so I’m think on taking this approach instead
How can one get the carbon filters? Interested…
It depends on the filter. I’ve got some 1 micron diesel style pp bags that has no luck. But 1 micron glass fiber air quality sampling filters will remove the fines. However, for some reason, carbon does not work well unless layered with t5. It’s a huge difference in ability to remove pigments

Has anyone ever experienced an issue with their oil/solvent turning a deep red after filtration? Or a horrible rancid smell?
Long story short, I tried two recent runs with filtration, partly because one of the extractions I ran had to sit in buckets somewhat open to atmosphere all weekend (long story) and I had a feeling it may have pulled in a lot of water solubles. I filtered this becuase it was dark black, and green as well. The oil was slightly warm after I pulled it from the rotovap and sent~140g of oil plus a liter or so of alcohol thru this T5/AC cake, and the solution turned bright red! It stayed this way thru the rest of the entire process…I assume some sort of acidification?
Now, yesterday I filtered some byproduct. This byproduct is basically kiefed plant material that I catch in a 25um screen, and I just rinse it thru a whatman filter until it runs clear to remove the cannabinoids stuck inside. It was deep green. I ran it thru a T5 cake that was maybe 50g in a buchner, no problems…threw on a ~15g AC slurry and when I filtered this, the color was great but I notice a weird bubbling type reaction when the liquid falls thru the filter for 10-15 seconds and my alcohol tincture smells rancid!
Huh ? Strangest thing pesticides ?
It’s very weird. It almost smells like when I use the AC scrub it pulls in water soluble thru the filter process. I did another T5 only afterwards and the smell is nearly gone but wow it stank horribly. Our facility has been using pesticides but as to what kind, I am not sure to be honest. May be something I need to look into.
The color on the new one is great and looks like someone peed in the jar. Is it important to use scrubbing materials like T5 or AC with post winterized material or is that not important?
It makes your crude cleaner before spd whatever you get out now helps
When pis colored you are already fearly clean so might not be necessary

Yes definitely. Our crude is normally amberish colored in thin layers but black as night when its in quantity. I certainly need to figure out where that rancid smell comes from after introducing AC to the filtration process though…
Layers in a sock filter work ya think? They don’t work mixed together in the oil after it’s cooked down?

So, filtering I’m doing right now. 152g bento, 92g silica and 52g t41 in the funnel. Did you try just cracking the valve, cause it makes all the difference to me seemingly. 25 min for 4.5 gal.

Please try it. Not sure how’d you’d do it. When the powder layers were disturbed and poorly separated in my buchner, I seemed to lose performance but didn’t repeat.
There’s been some discussion somewhere on here about reds getting ‘fixed’ after heating. Filtration works best if we do it before we use any heat that would promote degradation seems to be the general consensus.
I had a pretty rough odor that carried into my product after recovery, like a burnt rubber, or sulphur maybe, that could have either been the presence of actual sulphur or, as it was suggested by a fellow member, I might have ‘burnt’ my Terps by recovering at too high of a temperature for an extended period of time.
Just some food for thought.

For hexane extracts I am sure recovery temps matter
In my experience sulfur smells are only caused by sulfur, and are not remediable by any process of distillation or purging. While burnt terps have a quite different odor (more of a burnt/spoiled fish), and are reduced over long purge times or additional distillation passes.
I get rid of sulfur by placing copper s rubies in the head

Yeah, copper for sulphur to produce blue copper sulphate, I didn’t mean to imply we could remediate sulphur with powders.
I’m going to keep that difference in odor in mind when I do this next batch. I’m not really a good smell identifier so I definitely could’ve gotten what I was smelling exactly wrong.

Remediating sulfur by dwelling long on the temp smells came from the vac pump on IG

I don’t know, all I can say is I tried that and it did not work for me. I certainly pulled sulfur and it stunk up the whole room, but the original product wasn’t any more passable.
