Tip:
If the components are obviously contaminated, use 45:45:10 methanol/water/formic
acid.
2.
Place the vessels in the ultrasonic bath for 30 minutes.
3.
If you used formic acid in the cleaning solution, do as follows:
a.
Rinse the components by immersing them separately in glass vessels containing water
and then place the vessels in the ultrasonic bath for 20 minutes.
b.
Dry the components by immersing them in separate glass vessels containing
methanol, and then place the vessels in the ultrasonic bath for 10 minutes.
Notice:
powder-free gloves for the rest of this procedure.
4.
Carefully remove the components from the vessels, and blow-dry them using inert, oil-free
gas.
5.
Inspect each component for persisting contamination.
Requirement:
a.
Use the 1:1 methanol/water to rinse the component over the large beaker.
b.
Blow-dry the component with inert, oil-free gas.
Warning:
and to avoid spreading contamination, dispose of the components in accordance with local
environmental regulations.
6.
Inspect each component for persisting contamination.
Requirement:
before reassembling the ion block.

Assembling the source ion block assembly
4.20.3.1
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
Notice:
•
•
To avoid recontaminating the components, wear clean, chemical-resistant,
If contamination is present, do as follows:
To avoid personal contamination with biologically hazardous, or toxic materials,
If contamination is present, dispose of the component, and obtain a new one
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.
