4.15.8 Fitting the ion block support to the source
Required materials
• Chemical-resistant, powder-free gloves
• 3-mm hex wrench
• New seals and O-rings
To fit the PEEK ion block support to the source:
Warning:
To avoid personal contamination with biohazards, toxic materials, and corrosive
materials, wear chemical-resistant gloves when performing this procedure.
1. Ensure that the grooves for the PEEK ion block support O-rings are free from dirt and
debris.
Tip:
If contamination is present, use 1:1 methanol/water, applied to a lint-free cloth, to
carefully clean the grooves.
2. Fit the O-rings (new ones if you disposed of the old) to the PEEK ion block support.
Tip:
To fit an O-ring in its groove, start fitting the O-ring at the notch in the groove, and
then progressively work the ring into the groove, in either direction from the notch.
3. Fit the PEEK ion block support to the instrument’s housing.
4. Use the 3-mm Allen wrench to fit and tighten the four PEEK ion block support securing
screws.
5. Fit the ion block assembly to the PEEK ion block support (see Fitting the ion block
assembly to the source assembly ).
6. Fit the source enclosure to the instrument (see Fitting the source enclosure to the
instrument ).
