5. Inspect each component for persisting contamination.
Requirement:
If contamination is present, dispose of the component, and
obtain a new one before reassembling the ion block.
Assembling the source ion block assembly
Required materials
• Clean, chemical-resistant, powder-free gloves
• Combined 2.5-mm Allen wrench and cone extraction tool
• Needle-nose pliers
• Isopropyl alcohol in a small container
To assemble the ion block assembly:
1. Fit the extraction cone seal to the ion block.
2. Fit the extraction cone handle’s insulator onto the extraction cone
handle.
3. Fit the extraction cone onto the ion block.
4. Fit the 2 PEEK extraction cone retainer clips onto the ion block.
Warning:
To avoid spreading contamination, dispose of the
components in accordance with local environmental
regulations.
Notice:
• To avoid recontaminating the ion block assembly, wear clean
chemical-resistant, powder-free gloves during this procedure.
• To avoid damaging the fragile extraction cone, do not place it on its
tip; instead, place it on its flanged base.
Notice:
To avoid damaging the extraction cone aperture, take
great care when fitting the extraction cone to the ion block.
