• Method parameters
• Column type
• Operating pressure
• Carrier gas
You might also be asked to provide the firmware versions of your GC instruments.
To check the firmware version on the 5890, 6890, 6890 Plus or the 6890N GC, power on
the instrument. The firmware version is displayed on the LCD.
To check the firmware version on the injector towers and controllers:
1. On the instrument keypad, press Options.
2. Scroll down to Instrument Status and press Enter.
3. Scroll down. The instruments are shown as follows:
• Smplr:model&firmware
• F inj:model&firmware
• B inj:model&firmware
4.1 Gas System Troubleshooting
A poorly functioning gas system can cause problems in your Empower GC system. Before
proceeding to Section 4.2, check these gas system components.
Regulators
To check the regulators, set the instrument for a constant pressure of 8 psi. Then use the
manifold pressure (on the regulator, not the tank) to adjust the pressure to a constant flow
at 8 psi.
Tanks
Ensure there is adequate pressure in the tanks. The lower the pressure in the tank, the
more erratic the pressure and flow readings. As a rule, the tank should be replaced when
its pressure falls below 100 psi. Follow your standard operating procedure for replacing the
tank.

If you are using a split/splitless inlet, consider using the 6890 Gas Saver option, which
reduces carrier gas consumption and allows you to reach pressures that may otherwise be
difficult to achieve.
