Flow Rates For The Xevo G2 Qtof System - Waters Xevo G2 QTof Operator's, Overview And Maintenance Manual

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.
Flow rate versus temperature and gas flow:
Flow rate
(mL/min)
0.000 to 0.020
0.020 to 0.100
0.101 to 0.300
0.301 to 0.500
>0.500

Warning:
exposure to toxic substances, never place containers on top of the
instrument or on its front covers.
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
