I’m having some serious color issues with my remediated Distillate. We’re inputting golden or slightly reddish distillate and post rotovaping/solvent removal we’re getting a dark green color. We cryo extract using ethanol cooled that has been chilled in a dry ice/ethanol bath and winterize it again before running it through the chromatography. We used Interchim 520xs flash with their 128 mm C18 columns. We have not done color remediation as the product we’re light in color to begin with. We use an 80/20 Methanol/water ratio and rotovap at 50 C. When prepping solution we often observed a dark red color but some of the solution were golden in color. We have not adjusted the pH of the solutions at any point or tested the pH. My guess is it’s oxidation of some of the impurities the may be fixable by adjusting the pH. Any ideas? Color remediation? When should we CRC? I’m thinking post ethanol extraction as it’s already in solution to save money and steps of dissolving and and solvent evaporation. The prechromatography solution is too viscous to filter. Thank you for any advice.

Johnny, its likely chlorophyll. Run it on gc/ms.
Don’t run CRC on any remediated products the T5/T41 will cause some of your cbd to turn into THC.
The color is likely due to a concentration of chlorophyll when you perform your remediation (chlorophyll is pretty polar). I’d recommend doing CRC on the crude in order to remove the chlorophyll from your oil in the first place to avoid significant discoloration in your final, remediated product.
We’re running distillate and there is no Green color. I’m going to try short path again because I have that in the Lab ready to go. I’ll get back to everyone tomorrow when it’s finished. Thank you for the help!
did that green distillate pick up any odor?
@CO_Chromatography You can lead a horse to water 
Why do u think that? Unless youve had experiences with the powder coming through, i dont think it would, but idk
Because acid washed clays convert CBD to THC
Correct the ph and you’re fine
Don’t have a go in the lab and my precious coworker spent too much on analysis.
Thank you, had read that before but haven’t done any CRC to experience it myself and had forgotten it does that.
I figure it’s chlorophyll, interesting it turns red in solution or while under heat and the distillate is mostly clear to orangish. We sent back our chromatography instruments but I still have some samples prep to run. It’s red and dark.
I had a sample that was a light brownish color and it made this awesome peanut brittle crumble T-Free distillate.
Hello Demontrich, can you be more specific, what behavior are you referring to? If offering help with filtration issues is considered spam, please let me know. I truly wish to understand what it is your getting at. If you don’t like that fact that I have 39 years of filtration experience and that I’m bringing that experience to those you need it in this industry, then I guess I’m doing something wrong. But I will tell you we have fortunately been able to help dozens of customers off this site. Again, can you be specific? Or call me, lets go through this, 310-212-7777 Nothing to hide and we wish to be a part of this community. Thanks, Greg
