Installing the GC 1
Agilent 7890B Installation 31
Install hydrogen sensor calibration gas
If available, install the hydrogen sensor calibration gas. The
hydrogen sensor ship kit includes a pressure regulator that
installs directly onto the calibration gas cylinder. Agilent also
provides sufficient copper tubing and hardware to connect the
pressure regulator to the hydrogen sensor assembly calibration
gas input fitting.
1 Set the gas cylinder stand upright on the lab bench near the
GC. (Do not place it behind the oven exhaust vent!)
2 Turn the pressure regulator completely off and set the
output pressure as low as possible (full CCW).
