Flow rates for the Xevo G2 QTof system
The Xevo G2 QTof system can run at high flow rates. To optimize desolvation,
and thus sensitivity, run the system at appropriate gas flows and desolvation
temperatures.
Preparing the IntelliStart Fluidics system
For additional information, see “Connecting the liquid waste line” on
page B-15 .
Installing the reservoir bottles
Use standard reservoir bottles (30-mL) for instrument setup and calibration.
Use the Low-volume Adaptor Kit (included) to infuse smaller volumes. The
low-volume vials have a volume of 1.5 mL.
Required materials
Chemical-resistant, powder-free gloves

Warning:
To avoid injuries from broken glass, falling objects, or
exposure to toxic substances, never place containers on top of the
instrument or on its front covers.
