Cleaning the ion block assembly 4-51
6. Inspect each component for persisting contamination. If contamination
is present, dispose of the component, and obtain a new one before
reassembly.
Assembling the source ion block assembly
Required materials
• Chemical-resistant, powder-free gloves
• Combined 2.5-mm Allen wrench and cone extraction tool
• Needle-nose pliers
• Isopropyl alcohol in small container
To assemble the ion block assembly
1. Fit the extraction cone seal to the ion block.
2. Fit the extraction cone handle insulator to the extraction cone handle.
3. Fit the extraction cone to the ion block.
4. Fit the 2 PEEK extraction cone retainer clips to the ion block.
5. Use the combined 2.5-mm Allen wrench and cone extraction tool to
tighten the captive screw securing each extraction cone retainer clip to
the ion block.
Warning:
The components can be contaminated with
biohazardous and/or toxic materials. Dispose of them
according to local environmental regulations.
Caution:
• To avoid recontaminating the ion block assembly, wear clean
chemical-resistant, powder-free gloves during this procedure.
• The extraction cone is fragile. Never place it on its tip; always place
it on its flanged base.
Caution:
Take great care not to damage the extraction cone
aperture when fitting the extraction cone to the ion block.
