Reassembling the L1, L2, L3 Lens Assembly
Ensure that the lenses are clean and dry before you reassemble the lens assembly.
Y To reassemble the L1, L2, L3 lens assembly
1. Wearing clean, lint- and powder- free gloves, reinstall the lenses and spacers in the lens
holder in the order and orientation shown in Figure 53 on page 91 , starting with lens L3.
2. Reinstall the lens clip by pinching the ends with your fingers or a pair of tweezers and
seating it in the lens holder.
3. Insert the lens alignment tool (in the TSQ Quantum XLS Accessory Kit) into the lens
assembly and align the lenses.
Reinstalling the Ion Source Lens Assemblies
Y To reinstall the ion source lens assemblies onto the ion source
1. Wearing clean, lint- and powder- free gloves, insert the three heater cartridges of the ion
source through their corresponding holes in the L1, L2, L3 lens assembly. See Figure 52
on page 90 .
2. Insert the three heater cartridges of the ion source through their corresponding holes in
the heated Q0 quadrupole assembly. Verify the correct orientation of the guide pin hole
and the retainer clip groove on the heated Q0 quadrupole assembly.
3. Use the retainer clip and threaded standoff to secure the lens assemblies to the ion source.
Reinstalling the Ion Source
For the location of the ion source components, see Figure 50 on page 86 .
Y To reinstall the ion source into the vacuum manifold
1. Wearing clean, lint- and powder- free gloves, place the ion source onto the magnet yoke.
2. Position the ion source in the vacuum manifold and ensure the following:
• The transfer line is seated in the sample inlet aperture in the ion source.
• The guide pin on the Q0 quadrupole mount inserts into the guide pin groove on the
heated Q0 lens assembly.
• The two thumbscrews are aligned with the screw holes in the Q0 quadrupole mount.
3. Secure the ion source to the Q0 quadrupole mount by alternately tightening each
thumbscrew one-half turn at a time. Make sure there is no play in the ion source.
IMPORTANT For accurate temperature readings of the heater block, fully screw the
threaded standoff into the ion source to ensure contact between the temperature
sensor and the heater block.
