Note that no optimisation was attempted using the Trap Current. Increasing the trap current
request can significantly improve source sensitivity. If the instrument trap current is to be
changed the instrument will require retuning as described above.
If instrument linearity cannot be achieved easily with the source parameters inside of the
acceptable limits other factors outside of instrument tuning must be considered. These other
factors include:
Leaks
Poor quality gas
Contamination in the ion source
Filament distance from the ion box (Bad filament position)
