4.21.5
Fitting the ion guide assembly to the source assembly
4.21.5.1
Required material
Clean, chemical-resistant, powder-free gloves
Warning:
Warning:
spreading contamination to uncontaminated surfaces, wear clean, chemical-resistant,
powder-free gloves when working with the source components.
Notice:
To avoid damaging the ion guide assembly when fitting it to the source assembly,
avoid pushing on the metal ion guide lens plates. Instead, handle the ion guide assembly
using the circuit boards on both sides of the assembly.
To fit the ion guide assembly onto the source assembly:
1.
Slide a short length of the ion guide assembly's differential aperture end into the adaptor
housing so that the arrows on the front circuit board carrier point upward.
2.
Carefully slide the assembly fully into place.
4.21.6
Fitting the ion block support to the source
4.21.6.1
Required materials
•
Chemical-resistant, powder-free gloves
•
3-mm Allen wrench
•
New seals and O-rings
Warning:
spreading contamination to uncontaminated surfaces, wear clean, chemical-resistant,
powder-free gloves when working with the source components.
To fit the PEEK ion block support onto the source:
1.
Ensure that the grooves for the PEEK ion block support O-rings are free of 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) onto 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 onto the instrument's housing.
4.
Use the 3-mm Allen wrench to fit and tighten the 4 screws securing the PEEK ion block
support.
5.
Fit the ion block assembly onto the PEEK ion block support (see
