Hey guys I've been running into some issues with my distillation potency, and I feel like it is happening at my winterization/filtration.
My distillate is coming out at ~75% D9THC and ~4% THCa, I have a UPLC and a background in analytical chemistry so I am confident that this is accurate. I run a spinning band instrument for my distillation and during my main body fraction I can visibly see striations in my oil. My mantle temp during the main body is ~200c, vacuum is at 0.01mmhg or 10micron, vapor temp at ~255c. The distillate smells great, tastes great, is almost transparent - if put into a vape pen it doesn't even look filled - but the potency is relatively low.
During distillation I don't collect the body fraction until it is well into the correct ranges for C-21 fractions, and usually end my fraction once the color begins to change or if my mantle/vapor temp delta starts to stray.
I have tested my winterized oil prior to the run and it came back at ~55% D9THC. I dilute my crude oil pretty significantly in ethanol, put it into a freezer at -20c for 24 horus, and preform the first filtration within the freezer. I filter through dual hochstrom filters using 1 micron pore filter paper at 300torr. After the initial filtration I allow the material to freeze for 24 hours. Before the second filtration I add carbon and filter through another 1 micron hochstrom at 200torr.
Admittedly I have not ran potency on my crude oil, but I am using a Co2 SFE and get a TON of fat. I generally extract ~10% potency trim.
I am absolutely dumb-founded as to why my potency on my distillate is so low. Other people utilizing the same distillation techniques are hitting 85%++. Any tips, tricks, or general discussion would be greatly appreciated.
