2-2 Preparing the Mass Spectrometer for Operation
Starting the mass spectrometer
The Waters Xevo G2 QTof is compatible with the ACQUITY UPLC and
nanoACQUITY UPLC systems. If you are not using either system, refer to the
documentation relevant to your LC system (see “Software and data system” on
page 1-6 ).
Requirement:
Power-on the instrument server or workstation PC first, to
ensure that it obtains the IP addresses of the system instruments.
See the mass spectrometer’s online Help for details.
To start the mass spectrometer:
1. On the rear panel, ensure the nitrogen supply is connected to the
instrument’s nitrogen inlet connection (see the figure on page B-2 ).
Requirement:
The nitrogen must be dry and oil-free, with a purity of at
least 95%. Regulate the supply at 600 to 690 kPa (6.0 to 6.9 bar, 90 to
100 psi).
2. Ensure that the collision gas supply is connected to the instrument’s
collision cell gas inlet.
Requirement:
The collision gas is argon; it must be dry and of high
purity (99.997%). Regulate the supply at 50 kPa (0.5 bar, 7 psi).
3. Power-on the instrument server or workstation PC.
4. Switch on the Xevo G2 QTof at the power outlet.
5. Press the power switches of the ACQUITY instruments.
Result:
Each system component runs a series of startup tests.
Caution:
Using incompatible solvents can cause severe damage to the
instrument. For more details, refer to the following sources:
•
Appendix C , “Materials of Construction and Compatible Solvents” ,
for mass spectrometer solvent information.
• Appendix C of the ACQUITY UPLC System Operator’s Guide for
solvent compatibility with ACQUITY devices.
Warning:
To avoid ignition of flammable solvents, never let the nitrogen
supply pressure fall below 690 kPa (6.9 bar, 100 psi).
