a.
Rinse the components by immersing them separately in glass vessels containing
water and then placing the vessels 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:
To avoid recontaminating the components, wear clean, chemical-
resistant, 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:
If contamination is present, do as follows:
a.
Use the wash bottle containing 1:1 methanol/water to rinse the component over the
large beaker.
b.
Blow-dry the component using inert, oil-free gas.
Warning:
To avoid spreading contamination, dispose of all waste materials
according to local environmental regulations.
6.
Inspect each component for persisting contamination. If contamination is present, dispose
of the component, and obtain a new one before reassembly.
4.14.4 Assembling the source ion block assembly
Required materials
• Chemical-resistant, powder-free gloves
• Combined 2.5-mm hex wrench and cone extraction tool
• Isopropyl alcohol in small container
• HPLC-grade (or better) 1:1 methanol/water
• Lint-free cloth
To assemble the ion block assembly:
Note:
To avoid recontaminating the components, wear clean, chemical-resistant, powder-free
gloves for the rest of this procedure.
Notice:
To avoid damaging the heater cartridge assembly wires, do not bend or twist
them when removing the assembly and ceramic heater mounting block from the ion
block.
