Removing the differential aperture from the ion guide
Required material
Small, flat-blade screwdriver
To remove the ion guide differential aperture:
1. Use the small, flat-blade screwdriver to remove the 3 slotted screws that
secure the differential aperture to the 3 supporting rods.
2. Remove the differential aperture from the ion guide.
Notice:
To avoid a reduction in sensitivity, remove and clean the
differential aperture only when cleaning the ion guide assembly
fails to remove all visible contamination from the differential
aperture. Sensitivity can diminish if the differential aperture fails
to correctly align with the ion guide during refitting.
