To power-off the TSQ 9000 system:
Note If you are running samples, stop the acquisition before powering off the system.
1. Cool down the GC. If you do not plan to replace the column or perform maintenance on
the GC, you do not have to lower the injector temperature.
Note If you are using hydrogen as a carrier gas, you must cool down and shut off the
GC to prevent the buildup of hydrogen in the vacuum manifold.
2. Open the TSQ 9000 Dashboard and click the Shut Down button.
3. Click the Yes button to continue the shutdown process. The heaters and turbomolecular
pump power off. Once the turbomolecular pump reaches 50% rpm, the foreline pump
powers off, and you may vent the system.
4. When the TSQ 9000 system's temperatures and pumps are ready for shutdown, the
vacuum light on the front of the instrument will start blinking rapidly.
5. Reach over to the left side of the instrument and push down on the power switch to
power-off the TSQ 9000 mass spectrometer.
