CO2 in natural gas

[Jobrag]

Does any one know of a device that will measure the percentage of CO2 (about 5% and resolution down to 0.1%) in natural gas, in real time, the gas is at approx 40 bar and 30 Deg C.
Thank you

No, we have a gas chromatograph but the response is too slow, I'm trying to catch a rise in CO2 that is faster then the chromatograph will see.
