CO analyser for hydrogen stream (PSA)

[sfacchin]

Please,
can someone indicates a CO analyzer for a high purity hydrogen stream (product of a PSA unit)?
The resolution needed is in the ppm level.
Thanks

Perhaps our good friends at air liquide can help you? Or the vendor of you PSA in general?

Maybe simple gas photometry (infrared) could be used. You can easily get something between 1 to 5ppm resolution.

Be careful, as some of the methods for CO have a STRONG cross-sensitivity to hydrogen. Lots of people do this measurement though- just get good references before you buy anything.

Try Servomex. I am not sure about this combination but they build some very good gas analyzers.

I vote for the infrared absorption type. I'm pretty sure GE Sensing has one. No cross-sensitivity issues.

Good on ya,
