4-40 Maintenance Procedures
4. Carefully remove the extraction cone from the vessel, and blow-dry it
using inert, oil-free gas.
5. Inspect the extraction cone for persisting contamination. If
contamination is present, do as follows:
a. Use the wash bottle containing 1:1 methanol/water to rinse the
extraction cone over the large beaker.
b. Blow-dry the extraction cone with inert, oil-free gas.
6. Inspect the extraction cone for persisting contamination. If
contamination is present, dispose of the extraction cone, and obtain a
new one.
Fitting the extraction cone to the ion block
Required materials
• Chemical-resistant, powder-free gloves
• Combined 2.5-mm Allen wrench and cone extraction tool
To fit the extraction cone to the ion block
1. Fit the extraction cone handle insulator to the extraction cone handle.
2. Fit the extraction cone to the ion block.
Caution:
To avoid recontaminating the extraction cone, wear
clean, chemical-resistant, powder-free gloves for the rest of this
procedure.
Warning:
The extraction cone can be contaminated with
biohazardous and/or toxic materials. Dispose of it according
to local environmental regulations.
Warning:
The ion block can be contaminated with biohazardous
and/or toxic materials. Always wear chemical-resistant,
powder-free gloves while performing this procedure.
