Cleaning the ion block assembly
Clean the ion block assembly if cleaning the sample cone and cone gas nozzle fails to
increase signal sensitivity.
Removing the ion block assembly from the source assembly
Required materials
• Chemical-resistant, powder-free gloves
• Combined 2.5-mm Allen wrench and cone extraction tool
To remove the ion block assembly:
1. Vent and shut down the mass spectrometer (see the mass spectrometer’s online Help
for details).
2. Disconnect the power cords for the mass spectrometer and both roughing pumps
from the main power source.
3. Remove the source enclosure (see page 98).
Rationale: Removing the source enclosure aids access to the ion block assembly.
4. Close the source isolation valve (see page 104).
Warning: The source components can be contaminated with biohazardous
and/or toxic materials. Always wear chemical-resistant, powder-free gloves
while performing this procedure.
Warning: To avoid personal injury, as well as damage to the roughing
pumps and mass spectrometer, disconnect the power cords for the mass
spectrometer and roughing pumps from the main power source.
Warning: The source can be hot. To avoid burn injuries, allow it to cool for
at least 30 minutes before proceeding.
Warning: To avoid puncture wounds, take great care while working with
the source enclosure open if one or both of these conditions apply:
• An ESI probe is fitted (the probe tip is sharp).
• A corona pin is fitted (the pin tip is sharp).
