13. For optimal performance, wait at least 30 minutes for the ion source to heat up to the
same temperature as the inside of the instrument. Otherwise, the masses or intensities
may be different
.
IMPORTANT When inserting a cold ion source cartridge such as after cleaning, the ion
source and lens stack will expand as the source cartridge heats, often pushing the ion
volume and lenses away from the rear of the instrument where they are firmly held by the
RF Lens spring contacts. Inserting the source with the gap shown in the tip above can help
prevent contact issues.
1. Click Shut Down on the TSQ Series Dashboard.
Note You must shut down and vent the mass spectrometer even if your instrument has a
vacuum interlock.
2. Click Yes to continue the shutdown process. The high voltages, heaters, and
turbomolecular pump power off. Once the turbomolecular pump reaches 50% speed, or
five minutes elapses, the foreline pump powers off and you may vent the system.
Note The amber vacuum light on the front of the instrument starts blinking rapidly,
indicating the mechanical pump has powered off after a five minute period with the
turbomolecular pump off (such as when the instrument is shut down), or due to a
sustained vacuum fault lasting five minutes. When the turbomolecular pump spins down
below 50% speed due to the shut down process, the vacuum light turns off.
3. Reach around the left side to the back of the instrument and push down on the power
switch to power-off the instrument.
4. Open the front door of the TSQ 9000 mass spectrometer.
