tool to tighten the retainer clip securing screws.
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. Open the source isolation valve (see “Operating the source isolation
valve” on page 4-11 ).
4. Close the source enclosure.
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, because the ESI probe tip is sharp.
Caution:
To avoid recontaminating the ion block assembly, wear clean
chemical-resistant, powder-free gloves during this procedure.
