Waters Xevo TQD - Running the Instrument at Different Flow Rates

Starting the mass spectrometer 2-5
Running the instrument at different flow rates
The ACQUITY UPLC system runs at high flow rates. To optimize desolvation,
and thus sensitivity, run the ACQUITY Xevo TQD system at appropriate gas
flows and desolvation temperatures. IntelliStart software automatically sets
these parameters when you enter a flow rate, according to the following table.
If you are using an APCI interface, IntelliStart software automatically sets
the parameters according to the following table:
