Maintaining the API Stack
The API stack includes the spray shield, ion sweep cone, spray cone, ion

damaged. You also need to clean the spray shield, ion sweep cone, spray
cone, ion transfer capillary, tube lens, skimmer, and the other components of
the API stack on a periodic basis.
It is not necessary to vent the system in order to replace the ion transfer
capillary. To replace the ion transfer capillary, proceed as follows:
