1.5.1 The inner source assembly
The inner source assembly comprises a handle and a shaft, onto which you can attach
interchangeable sources by using a bayonet connection. The entire inner source assembly
attaches to the outer source assembly by way of the mounting flange assembly on the
instrument.
Removing the inner source assembly enables you to do the following:
• Change the filament
• Clean the ionization chamber
• Clean the repeller
• Change between EI and CI operation
