Preparing the mass spectrometer for
operation
This chapter describes how to start and shut down the mass spectrometer.

2.1 Preparing to start the mass spectrometer

This instrument is coupled to a GC oven via a heated transfer line.
Note:
For instructions on how to operate and maintain the GC oven, refer to the documentation
that accompanied it.
Note:
The gases you can use on the Xevo TQ-GC and the GC oven have very specific safety
requirements. To understand these requirements, see
Warning:
leak tightness and for consistent supply pressure. Avoid naked flames.
To prepare the mass spectrometer for startup:
1. In EI or CI mode, ensure that the collision gas supply is connected to the instrument's
collision cell gas inlet.
2. In EI or CI mode, ensure that the carrier gas supply is connected to the GC oven's gas inlet
connection. For instructions on connecting the supply to the oven, refer to the
documentation that accompanied the oven.
3. In CI mode only, ensure that the chemical ionization gas supply is connected to the
instrument's chemical ionization gas inlet.

2.2 Starting the mass spectrometer

Starting the mass spectrometer comprises powering-on the workstation, logging in, powering-on
the mass spectrometer and all other instruments, and starting the software.
