Investigating Sensitivity Issues
118 TSQ 9000 Hardware Manual
When you run Detector Check diagnostics on the TSQ 9000 system, the Xcalibur software
checks for noise on the electrometer, multiplier, dynode and RF board. Sensitivity issues are
usually the result of an air leak, dirty components, or contamination. Sometimes sensitivity
issues can be caused by simple to fix problems such as the carrier gas tank running out or a
sample not being injected into the GC. Before troubleshooting for sensitivity issues, look for
the simple problems. If the problem is more complex, then check for air leaks or dirty
components. You can prevent these types of problems by properly cleaning and maintaining
your GC/MS system. It is normal to see a decrease in sensitivity in the first few injections on a
clean system.
Before troubleshooting for sensitivity issues, look for simple solutions, such as fixing a clogged
autosampler syringe or raising the level of your sample. You can always prevent sensitivity
issues from occurring by keeping your GC/MS system clean and free of contamination.
WARNING
issue that requires removing a cover on the TSQ 9000 mass spectrometer,
you should power-off and vent the instrument to avoid harming yourself.
