Hydrogen purity analyzer - lube oil re-refinery

[Covalence]

Any advice on the best way to measure hydrogen purity in a re-refinery? Customer wants to do this with an in-line device, whereas they are currently taking samples and bringing it into the lab. Thank you.

Thermal conductivity technology is used to monitor the purity of H2 used as cooling medium in electric generators.
