1 Installing the GC
34 Installation and First Startup
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.
The gas cylinder is pressurized. Do not place the cylinder on its side or behind the oven
exhaust vent!
2 Turn the pressure regulator completely off and set the output pressure as low as possible
(full CCW).
3 Install the pressure regulator onto the calibration gas cylinder (it screws on).
