Recommendation:
Clean the differential aperture (see
Cleaning the differential aperture
) 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
Cleaning the ion guide assembly (Page 45)
6. Remove the differential aperture O-ring.
7. Disconnect the five electrical connectors from the ion guide, leaving them attached to the
pumping block.
