I am runing continuous flow system with a Carlo Erba EA, ConfloII, and
Delta S.
I am setting up a new tank of CO2 reference gas and am not clear on the
concept of, or need to worry about fractionation in a tank of CO2 at 800

psi. Should I reduce the pressure so that all the CO2 is in the gas
phase( what pressure would that be ). Or is combination gas/liquid phase

not a problem.
Thanks in advance for input.
