5. Close the source enclosure.
Cleaning the extraction cone
Clean the ion block and extraction cone if cleaning the sample cone and cone
gas nozzle fails to increase signal sensitivity. You must remove the ion block
assembly from the source assembly in order to clean the extraction cone.

2. Disconnect the power cords for the mass spectrometer and roughing
pump from the main power source.
