To clean the ion block components
1.
Immerse the ion block and isolation valve in separate glass vessels
containing 1:1 methanol/water.
If the components are obviously contaminated, use 45:45:10
Tip:
methanol/water/formic acid.
2.
Place the vessels in the ultrasonic bath for 30 minutes.
Requirement:
follows:
•
Rinse the components by immersing them separately in glass
vessels containing water and then placing the vessels in the
ultrasonic bath for 20 minutes.
•
Remove any residual water from the components by immersing
them in separate glass vessels containing methanol and then
placing the vessels in the ultrasonic bath for 10 minutes.
3.
Carefully remove the components from the vessels, and blow-dry them
using inert, oil-free gas.
4.
Inspect each component for persisting contamination.
Requirement:
a.
Using the wash bottle containing 1:1 methanol/water, rinse the
component over the large beaker.
b.
Blow-dry the component with inert, oil-free gas.

Maintenance Procedures
The ion block components can be contaminated with
Warning:
biohazardous and/or toxic materials. Always wear
chemical-resistant, powder-free gloves while performing this
procedure.
Formic acid is extremely corrosive and toxic. Work with
Warning:
extreme care, use a fume hood and suitable protective equipment.
If you used formic acid in the cleaning solution, do as
To avoid recontaminating the components, wear clean,
Caution:
chemical-resistant, powder-free gloves for the rest of this
procedure.
If contamination is present, do as follows:
