CO2 reading below 100ppm on samples of ambient air. CO reading accurately.
Hi plisk01 ,
Were you able to resolve your issues? Do you have any updates that may help the Agilent Community with more information?

Based on the original question, it sounds like you're doing dissolved gas analysis. Is this correct? How does the peak shape of CO2 look? It could be that some of it is being cut due to a valve switch and not reaching the methanizer. An example chromatogram, method settings, and plumbing diagram will be helpful in troubleshooting.
Hi all, thank you very much for your responses and sorry for the delay in replying. It was in fact a valve switching issue. Our catalsyst had become poisoned and the part needed repaired. As a result of this rework the timings had to be adjusted. Unfortunately our gc expert left the company and we were resolving the issues relatively blind to the process. But got there in the end. Thanks again for the help.
I will mark this as assumed answered due to its age, feel free to update us with what you found or post again if this is still an issue.
