Cleaning the extraction cone 5-45
Fitting the ion block assembly to the source assembly
Required materials
• Chemical-resistant, powder-free gloves
• Combined 2.5-mm Allen wrench and cone extraction tool
To fit the ion block assembly to the source assembly:
1. Fit the ion block assembly to the PEEK ion block support.
2. Use the combined 2.5-mm Allen wrench and cone extraction tool to fit
and then slowly tighten the 4 ion block assembly securing screws
sequentially and in small increments.
3. Ensure that the source isolation valve is closed (see page 5-14 ).
4. Fit the source enclosure (see page 5-10 ).
5. Connect the power cords for the mass spectrometer and roughing pump
to the main power source.
Warning:
The source components can be contaminated with
biohazardous and/or toxic materials. Always wear
chemical-resistant, powder-free gloves while performing this
procedure.
Warning:
To avoid puncture wounds, take great care while working with
the source enclosure open if one or both of these conditions apply:
• An ESI probe is fitted (the probe tip is sharp).
• A corona pin is fitted (the pin tip is sharp).
Caution:
To avoid recontaminating the ion block assembly, wear clean
chemical-resistant, powder-free gloves during this procedure.
