I need to analyze CO, CH4, and CO2 in a mixture but my technician says I can detect CH4 and CO2 in porapak and CO and CH4 in MolSieve but I want to detect all three simultaneously. Could anybody suggest a workable column for this need?

I used to run 3C Fixed Gases/ASTM1946 for Hydrogen/Helium, Oxygen, Nitrogen, CO, CH4, and CO2 on a GS-GasPro column. The temperature ramp was from -80C to 80C, with CO2 eluting around 7.5 minutes if memory serves.
