2.
Fit the extraction cone onto the ion block.
3.
Rotate the 2 PEEK extraction cone retainer clips to secure the extraction cone, then use the
combined 2.5-mm Allen wrench and cone extraction tool to tighten the retainer clip securing
screws.

gloves when working with the source components.
Warning:
enclosure open; the ESI probe tip is sharp.
Notice:
To avoid recontaminating the ion block assembly, wear clean chemical-resistant,
powder-free gloves during this procedure.
To fit the ion block assembly to the source assembly:
1.
Fit the ion block assembly onto 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
4.
Close the source enclosure.
4.20 Cleaning the ion block assembly
Clean the ion block assembly when cleaning the sample cone, cone gas nozzle, and extraction
cone fails to increase signal sensitivity.
