6. Reconnect the electrical connector inside the vacuum manifold
follows:
a. Using your fingers, align the connector's holes with the feedthrough, and then slowly
push the connector into the feedthrough.
b. Route the connector wire below the outer cage, away from the path of the inner cage.
7. Reinstall the ion source interface (see
8. Start up the system as described in
page 37.
Chemicals accumulating on the surfaces of the MP0 and MP1 ion guides form an insulating
layer that can modify the electrical fields controlling ion transmission. Clean ion guide
components are essential to properly operate the mass spectrometer. The cleaning frequency
depends on the type and quantity of the compounds that you analyze.
To clean or replace the MP0 and MP1 ion guide components, follow these procedures:
1. Removing the Top Cover of the Mass Spectrometer
2. Removing the Vacuum Manifold's Top Cover
3. Removing the MP0 and MP1 Ion
4. Cleaning the MP0 and MP1 Ion Guides, Lens L1, and the Split Gate
5. Reinstalling the MP0 and MP1 Ion
6. Reinstalling the Top Cover of the Mass
