Changing Operational Configuration
Changing between ionization configurations requires swapping the source and/or
placing the transfer line into its proper position for that mode. In this section, the
major steps for each possible conversion are listed, followed by a series of
general descriptions for handling the key steps in the conversion process.
The following steps are required for any system reconfiguration:
•
Go to “Turning Off the Mass Spectrometer” on page 34.
•
Go to "Removing the Analyzer Assembly” on page 37.
Perform appropriate change procedure described below.
•
Go to “Reinstalling the Analyzer Assembly” on page 44.
•
Go to “Turning On the Mass Spectrometer” on page 46.
