2-2 Preparing the Mass Spectrometer for Operation
Starting the mass spectrometer
This instrument 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 the Xevo
TQ MS” on page 1-4 .
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 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 1-16 ).
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 (99.9%). 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:
•
Appendix B , “Materials of Construction and Compliant 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).
