Maintaining the Ion Source Interface Assembly
The ion source interface assembly includes the ion sweep cone, ion transfer tube, capillary
heater assembly, S-lens or tube lens, and exit lens or skimmer. The ion transfer tube has a
finite lifetime. You must replace the ion transfer tube if the ion transfer tube bore becomes
corroded.
You can easily remove the ion sweep cone and ion transfer tube to clean or replace them
without venting the system. See “Maintaining the Ion Sweep Cone and Ion Transfer Tube” on
page 79.
To clean the ion source interface assembly components, other than the ion sweep cone and
ion transfer tube, follow these procedures:
1. Shutting Down and Venting the System
2. Removing the Ion Max or Ion Max-S Ion Source Housing
3. Removing the Ion Source Interface
4. Removing the S-Lens and Exit Lens (TSQ Vantage)
5. Cleaning the S-Lens and Exit Lens (TSQ Vantage)
6. Removing the Tube Lens and Skimmer (TSQ Quantum Access, TSQ Quantum Access
MAX, or TSQ Quantum Ultra)
7. Cleaning the Tube Lens and Skimmer (TSQ Quantum Access, TSQ Quantum Access
MAX, or TSQ Quantum Ultra)
8. Reinstalling the S-Lens and Exit Lens (TSQ Vantage)
9. Reinstalling the Tube Lens and Skimmer (TSQ Quantum Access, TSQ Quantum Access
MAX, or TSQ Quantum Ultra)
10. Reinstalling the Ion Source Interface Assembly
11. Reinstalling the Ion Max or Ion Max-S Ion Source Housing
12. Starting Up the System
Shutting Down and Venting the System
Shut down and vent the system. See “Shutting Down the System Completely” on page 52.
Removing the Ion Max or Ion Max-S Ion Source Housing
You must remove the Ion Max or Ion Max-S ion source housing to access the ion source
interface assembly. See “Removing the Ion Max or Ion Max-S Ion Source Housing” on
page 69.
