5-44 Maintenance Procedures
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.
Requirement:
If contamination is present, repeat the cleaning
procedure. If contamination is still 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.
3. Rotate the 2 PEEK extraction cone retainer clips to secure the extraction
cone, and then use the combined 2.5-mm Allen wrench and cone
extraction tool to tighten the retainer clip securing screws.
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.
