Cleaning the source hexapole assembly 5-61
7. Inspect the hexapole assembly for persisting contamination,
Requirement:
If contamination is present, do as follows:
a. Use the wash bottle containing methanol to rinse the source
hexapole assembly over the large beaker.
b. Blow dry the hexapole assembly with inert, oil-free gas.
8. Use the small flat-blade screwdriver to ensure that the hexapole
assembly screws are tight.
Fitting the hexapole assembly, PEEK ion block support, and ion
block assembly to the source assembly
Required materials
• Chemical-resistant, powder-free gloves
• 3-mm Allen wrench
• Lint-free cloth
• HPLC-grade (or better) 1:1 methanol/water
• New seals and O-rings
To fit the hexapole assembly and PEEK ion block support to the source:
1. Carefully fit the source hexapole assembly into the adaptor housing,
aligning the notches in the differential aperture at its rear with the two
bottom support rails on the analyzer assembly, and then carefully slide
the assembly fully into place.
2. Ensure that the grooves for the PEEK ion block support O-rings are free
from dirt and debris.
Caution:
To avoid recontaminating the source, wear clean,
chemical-resistant, powder-free gloves during this procedure.
Caution:
To avoid damage when fitting the hexapole assembly into the
adaptor housing:
• Avoid scratching the internal surfaces of the adaptor block.
• Do not compress the hexapole rods.
