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 98 . 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 the Lenses of the 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 51 .
2. Remove the ion source. See “Removing the Ion Source” on page 88 .
3. Remove the ion source lens assemblies from the ion source and disassemble it. See
“Removing the L1, L2, L3 Lens Assembly and the Heated Q0 Quadrupole Assembly” on
page 90 .
4. Clean the lenses and the spacers. See “Cleaning Stainless Steel Parts” on page 98 and
“Cleaning Non-Stainless Steel or Hybrid Parts” on page 100 , respectively.
5. Reassemble L1, L2, L3 lens assembly and install it and the heated Q0 quadrupole onto
the ion source. See “Reassembling the L1, L2, L3 Lens Assembly” on page 92 .
