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 biologically hazardous, toxic, and corrosive materials, wear chemical-resistant, powder-free 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 hex 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).
