Hi, I want to do the lithiation rnx and add CO₂ to quench the reaction to make the carboxylic acid. I have dry ice which is contaminant with some water and don't know how to transfer CO₂ to the system? Can anyone give me suggestion? Thank you very much!

Bit of an off the wall suggestion but you could buy canisters of CO2 gas and use a needle through the septum. You can buy them really cheap in bike shops (cycling). Like 3 euro for 3 or so. Can't think of anything else if your institution doesn't have bottled CO2.

If what you have is dry ice only, then pass the stream of sublimate through a drying tower which leads to your reaction.
