Cleaning Ion Volumes
You do not need to vent the mass spectrometer to atmosphere to clean the ion volume.
Y To clean the ion volume
1. Remove the ion volume. See “Removing the Ion Volume” on page 73 .
2. Clean the ion volume. See “Cleaning Stainless Steel Parts” on page 113 . If you are
cleaning a CI ion volume, be sure to clean out the small electron entrance hole.
Aluminum oxide can get trapped in this hole, which can adversely affect sensitivity. Use a
dental pick or old syringe needle to clean the hole.
3. Reinstall the ion volume. See “Installing the Ion Volume” on page 80 .
Cleaning Lenses of the TSQ Quantum XLS Ion Source
If cleaning the ion volume does not restore system performance, clean the ion source lenses.
Y To clean the ion source lenses
1. Shut down and vent the system. See “Shutting Down the System Completely” on
page 53 .
2. Remove the ion source. See “Removing the TSQ Quantum XLS Ion Source” on page 89 .
3. Remove the ion source lens assemblies from the ion source and disassemble it. See
“Removing the L1, L2, L3 Lens Assembly and the Q00 Quadrupole Lens Assembly” on
page 91 .
4. Clean the lenses and the spacers. See “Cleaning Stainless Steel Parts” on page 113 and
“Cleaning Non-Stainless Steel or Hybrid Part” on page 115 , respectively.
5. Reassemble L1, L2, L3 lens assembly and install it and the Q00 quadrupole onto the ion
source. See “Reassembling the L1, L2, L3 Lens Assembly” on page 93 .
CAUTION Burn Hazard . The ion volume might be hot. Allow the ion volume to cool
to room temperature before touching it.
CAUTION Shock Hazard . Unplug the TSQ Quantum XLS mass spectrometer before
proceeding.
CAUTION Burn Hazard . The ion source might be hot. Allow the ion source to cool
