2-2 Preparing for Operation
Starting the mass spectrometer
The Waters Xevo TQD is compatible with the ACQUITY UPLC system; if you
are not using an ACQUITY UPLC system, refer to the documentation relevant
to the system you are using (see “Non-ACQUITY devices for use with Xevo
TQD” on page 1-7).
Starting the mass spectrometer entails powering-on the ACQUITY
workstation, logging into the workstation, powering-on the mass spectrometer
and all other ACQUITY instruments, and starting the MassLynx software.
Requirement: You must power-on and log in to the ACQUITY UPLC
workstation first to ensure that it obtains the IP addresses of the system
instruments.
See the mass spectrometer’s online Help for details on MassLynx and
IntelliStart applications.
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 1-21).
Requirement: The nitrogen must be dry and oil-free, with a purity of at
least 95% or, for APGC use, at least 99.999%. Regulate the supply at 600
to 690 kPa (6.0 to 6.9 bar, 90 to 100 psi).
For more information on connections, see the figure on page 1-21.
2. Ensure that the collision gas supply is connected to the instrument’s
collison 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).
Caution: Using incompatible solvents can cause severe damage to the
instrument. For more details, refer to the following sources:
•See page C-1 for solvent information.
• Appendix C of the ACQUITY UPLC System Operator’s Guide for
solvent compatibility with ACQUITY™ devices.
Warning: To avoid igniting flammable solvents, never let the nitrogen
supply pressure fall below 400 kPa (4.0 bar, 58 psi).
