NOTICE
The fifth code in the model string of the 370XA engraved on the metal band of the
dome (refer image) indicates the carrier gas to be used. The letter code HE
indicates helium, and H2 indicates hydrogen.
To ensure the continuous operation of the analyzer, install two high
pressure carrier gas cylinders and connect them to the GC through a
manifold arrangement that permits the replacement of empty
cylinders without disrupting the operation of the analyzer.
The manifold arrangement can be a manual valve arrangement or a
commercially available "auto switch-over" dual regulator assembly.
