THCO Full Panel Results

Hi everyone,

I recently sent out our THCO for full panel analytics. I have attached a picture of the results below. We failed the panel for 2,3 butanedione. Can anyone tell me how this molecule is being formed or even ending up in my distillate? All of my residual solvent is being pulled off at way higher temps. Acetic acid boils at 120C and this has a much lower boiling point. Any input is appreciated. Thanks!

Maybe some side reaction of acetic anhydride?

Or maybe just something that elutes with the same retention time (nvm I just saw it said GC/MS)
