We have a researcher who would like to replace carbon dioxide in a Supercritical Fluid Extractor with nitrous oxide. A google search found a warning from 1993 that there is history of problems with this:
Does anyone on the list have experience with whether this problem still exists with newer equipment for this process or other best practices for managing this concern?
Thanks for any help with this.
