AutoTune
MassLynx can automatically
tune the mass spectrometer in
both APcI and electrospray
ionisation modes. AutoTune
ramps the settings for the
tuning parameters until they
are optimised to give the best
intensity, resolution and peak
shape.
To run AutoTune:
Press on the tune
page to turn on the API
gas, and select
Operate .
Choose AutoTune from the tune
page Options menu.
Press Setup to define the
AutoTune setup parameters.
There are two levels of AutoTune:
•
A full AutoTune starts from a
default set of tuning parameters.
•
A maintenance AutoTune starts from the current tuning parameters set in the
tune page and can be quicker than a full AutoTune.
A maintenance AutoTune can only be performed if the instrument is already
reasonably well tuned. If the current tuning is too poor AutoTune gives an error
and request a full AutoTune.
The Tune Mass parameter sets the mass to be tuned on. When satisfied with the
AutoTune setup parameters:
Press OK to exit.
Press Start .
The AutoTune status bar is updated to show the progress of AutoTune.
