Right-clicking the Server icon opens the shortcut menu shown in
. This menu
allows you to do the following:
• Choose
Manual Tune
to open the Tune window, where you can optimize the
performance of your Surveyor MSQ Plus MS detector for a specific application.
• Choose
Instrument Tune and Calibration
to display the Instrument Tuning and
Calibration wizard.
• Choose
Vent
to turn off the turbomolecular pump and vent the vacuum. If the system is
not under vacuum, the menu contains the Pump command. Choose
Pump
to pump
down the system. The Edwards forepump is not turned off by venting the system. To turn
off the Edwards forepump without turning off the MS detector, set the On/Off switch on
the forepump to the Off position.
• Choose
Exit
to close the server. If Xcalibur is running, exiting the server is not allowed
and the error message shown in
Figure 28.

Tune Window
The Surveyor MSQ Plus Tune window allows you to optimize the MS detector parameters
(manually tune) for your analytes and acquire data to a raw file (.raw). When you finish
tuning your MS detector for a compound of interest, you save the current values of the tuning
parameters in a tune file (.tune). In ESI, you empirically determine the optimal probe
temperature, needle voltage, and cone voltage for each application. In APCI, you empirically
determine the optimal probe temperature, corona current, and cone voltage for each
application.
