Flashthunder, I appreciate your comments. I need to point out I had an incomplete thought in the above post... I didn't end my search at 120F, 1000psi. I actually now use 70F, 1000psi. only because I haven't hooked up a chiller to take the extraction vessel down past ambient. I haven't done any research down passed 1000psi yet. I need to do more research myself about the different polarity and how it effects extraction. Can you share your insight with everyone? Or maybe help point in the direction of good reseach - I have read some articles awhile back from Greywolf, I will refresh my memory... Question: If you run your extraction vessel at 120F / 2000psi, what do you set your collection vessel(s) too?

My quality is clear enough to shatter.
I would love to hear what temp your running at.I'm not really interested in max solubility. I want the best quality and I've found that occurs slightly below 2000psi.
I often pull chlorophyll past 2500.

Waters sells a phase monitor for supercritical solubility measurements; I am just starting to learn how to use it. Pretty much you load a pure component (THC) for example, pressurize it with CO2 and heat it to see when it goes into solution. It's pretty cool, can't wait to play with it more for extraction/fractionation method development.H. Perrotin-Brunel, P. Cabeza Perez, M.J.E. van Roosmalen, J. van Spronsen, G.J Witkamp, C.J.

Mark V, what temperatures and pressures are your collectors at?[
Hey Flashthunder, i have been running some co2 extractions and i have been getting some oil carryover, any suggestions?
