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 29 ).
Starting the mass spectrometer entails powering-on the workstation, logging
in, powering-on the mass spectrometer and all other instruments, and then
starting the MassLynx or UNIFI software.
Requirement:
You must power-on and log in to the 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, IntelliStart,
and UNIFI software.
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 44 ).
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 44 .
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).
Notice:
To avoid causing severe damage to the instrument, use
compatible solvents only. For more details, refer to the following
sources:
• See
page 243 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).
