Investigating Filament and Lens Control Issues

Filament has burned out.

Table 12. Possible Remedies when Filament is Burned Out
Run a Filament Check diagnostic to narrow down the source of the problem. Then replace the filament, as described in
Filament.
Make sure the filament wires are still connected to the source interface board. See
Make sure the lens driver board is connected to its bracket. See

Filament does not last long.

Table 13. Possible Remedies to Prolong Filament Life
Run a Leak Check diagnostic to check the system for air leaks and then address them. Use the Tetrafluoethane gas to find the leak.
Reduce the emission current in Xcalibur.
Increase the time for your first scan until after the solvent peak has passed.

Diagnostics indicate there is a problem with lens voltages.

Table 14. Possible Remedies for Problems with Lens Voltages
Make sure the lens driver board is attached to the bracket. If the board isn't fully connected to the 20-pin feedthrough, you may get odd
results. See Lens Driver Board
Make sure the lenses are properly aligned in the ion cartridge sleeve.
Ensure that lens wires are not resting on metal surfaces.
Check the source interface board to make sure the filament wires are fully connected. See
details.

Filament Check diagnostics can test the filament and lenses of the TSQ 9000 mass
spectrometer. Handle the lenses with care. Damaged lenses may cause short circuits, which
may damage the lens drivers.
WARNING
issue that requires removing a cover on the TSQ 9000 mass spectrometer,
you should power-off and vent the instrument to avoid harming yourself.
