Diagnostics and Troubleshooting
TSQ Quantum XLS and TSQ Quantum GC System Diagnostics
Thermo Scientific
The TSQ Quantum XLS and TSQ Quantum GC system diagnostics can test many
components of the TSQ Quantum XLS and TSQ Quantum GC mass spectrometers. If there
is a problem with the instrument electronics, the diagnostics can often locate the problem.
Replacing a faulty PCB or assembly can usually correct the problem. After the PCB or
assembly is replaced, the diagnostic tests are rerun to verify the instrument is functioning
properly.

The TSQ Quantum XLS and TSQ Quantum GC system diagnostics are used to test the
major electronic circuits within the instrument and indicate whether the circuits pass or fail
the tests. If there is a problem with the instrument electronics, the system diagnostics can
often locate the problem.
The system diagnostics do not diagnose problems that are not electrical in nature. For
example, they do not diagnose poor sensitivity due to misaligned or dirty components or to
improper tuning. Therefore, it is important that the person running the diagnostics be
familiar with system operation and basic hardware theory as well as the details of the
diagnostics.
IMPORTANT Typically, only a Thermo Fisher Scientific Field Service Engineer runs
diagnostic tests because certain tests can overwrite system parameters.
Before calling a Thermo Fisher Scientific Field Service Engineer to run diagnostics, consider
the following:
• Did the system fail when you were running samples?
