No experience with this, but whenever a researcher wants to modify a process using commercial equipment I go back to equipment mfg for their recommendations/guidance. Of course, if this is in-house equipment that approach won't work..but I have received very helpful info with incubators, heating apparatus, gas-mixing devices and the like...
Good luck..

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.
