4 Maintenance Procedures
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
Caution:
chemical-resistant, powder-free gloves during this procedure.
To fit the hexapole assembly and PEEK ion block support to the source:
Caution:
adaptor housing:
• avoid scratching the internal surfaces of the adaptor block.
• do not compress the hexapole rods.
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. 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.
If contamination is present, use 1:1 methanol/water, applied to a
Tip:
lint-free cloth, to carefully clean the grooves.
3. Fit the O-rings to the PEEK ion block support. Fit new O-rings if any of
the old O-rings were disposed of.
To fit an O-ring in its groove, start fitting the O-ring at the notch in
