To clean the extraction cone:
1.
Immerse the extraction cone in the glass vessel containing 1:1 methanol/water.
Tip:
If the extraction cone is obviously contaminated, use 45:45:10 methanol/water/formic
acid.
2.
Place the vessel in the ultrasonic bath for 30 minutes.
3.
If you used formic acid in the cleaning solution, do as follows:
a.
Rinse the extraction cone by immersing it in a glass vessel containing water and then
placing the vessel in the ultrasonic bath for 20 minutes.
b.
Dry the components by immersing them in separate glass vessels containing methanol
and then placing the vessels in the ultrasonic bath for 10 minutes.
Notice:
chemical-resistant, powder-free gloves for the rest of this procedure.
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.
Warning:
and to avoid spreading contamination, dispose of the extraction cone in accordance with
local environmental regulations.
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
4.19.4.1
Required materials
•
Chemical-resistant, powder-free gloves
•
Combined 2.5-mm Allen wrench and cone extraction tool
Warning:
To avoid personal contamination with biohazards or toxic materials, and to avoid
spreading contamination to uncontaminated surfaces, wear clean, chemical-resistant, powder-free
gloves when working with the ion block.
To fit the extraction cone onto the ion block:
1.
Fit the extraction cone handle insulator onto the extraction cone handle.
To avoid recontaminating the extraction cone, wear clean,
To avoid personal contamination with biologically hazardous, or toxic materials,
