Investigating Sensitivity Issues

The most common and anticipated causes of loss of sensitivity that cause tuning to fail are 
contamination leading to necessary ion source cleaning and loss of calibration gas intensity 
due to depletion of the calibration gas. Sensitivity issues are usually the result of an air leak, 
dirty components, or contamination. Sometimes sensitivity issues can be caused by simple 
problems to fix such as running out of carrier gas or a sample failing to inject 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 should also check the calibration 
gas vial. Calibration gas needs to be replaced about every two years. You can always prevent 
sensitivity issues from occurring by keeping your GC/MS system clean and free of 
contamination.

WARNING  ELECTRICAL SHOCK HAZARD: 

 When troubleshooting any issue that requires 

removing a cover on the ISQ 7000 mass spectrometer, you should power-off and vent the 
instrument to avoid harming yourself.

AVERTISSEMENT RISQUE D’ÉLECTROCUTION

:  lorsque vous cherchez à résoudre un 

problème nécessitant d’enlever le couvercle du spectromètre de masse ISQ 7000, mettez 
hors tension et ventilez l’instrument pour éviter de vous blesser.
