4.
Remove the 3 slotted screws securing the differential aperture to the ion guide housing
using the flat-blade screwdriver, and then remove the differential aperture (see

Recommendation:
Clean the differential aperture (see
) before disassembling the
ion guide housing. If cleaning the differential aperture fails to increase signal sensitivity,
continue with this procedure, and then clean the ion guide (see
).
