Partial pressure of CO2 measurement

Partial pressure of CO2 measurement

(OP)
I need to run an experiment for CO2 corosion measurement and I need to do this with different values of partial pressure of CO2. therfore, I will appreciate any help about what the equations and the instruments that I need to use for this purpose.

RE: Partial pressure of CO2 measurement

Will there be any H2S involved? I presume not.

We would use a blended gas. Say if the highest fraction that we wanted was 20% CO2 in N2, we would buy a mix at 40%. Then it is just pressure regulators and gauges. If the test is not static (but with flowing gas) then you also need flow meters.
You could do it from pure gases but that is more difficult to get correct.

Thank you for your reply, actually I will used a pure gas with continous flow since it is available for me rather than the mixture. therefore, if that possible can you expalin steps and measurements involved in this situation.
