I would like to switch to chillers for all cooling needs (cold traps, gas injection temperature, column jackets, condensing coil/heatexchangers/etc) . However that's a huge cost up front so I will upgrade slowly over time. Until then I want to get away from dry ice/alcohol mixtures, as that gets expensive over time. It seems to me that using liquid nitrogen or liquid CO2 would be the most cost effective method of cooling at this point.
Before I pick some up though I have a few questions:
Is the use of either of these liquids both effective and efficient for all cooling needs? Which do they work for and which do they not?
How can the temperature of the liquids be controlled? Liquid nitrogen boils at -321F. How would I use it to get my gas to around -30F?
