For Yokogawa’s chromatography systems, the hydrogen carrier gas currently used is 99.999% pure. We plan to install a PSA system for hydrogen production to obtain gas with 99.99% purity – can this be used as a carrier gas for chromatography?

It is recommended to consult the manufacturer’s technical staff

Insufficient purity is not acceptable; if the concentration of the component being measured is high, for example on a % level, it can still be used, but if it’s at the ppm level it will affect accuracy
