Performing Routine Maintenance
2 ISQ 7000 Hardware Manual Thermo Scientific
There are only a few components of your ISQ 7000 instrument that require routine
maintenance, depending on the quantity and types of samples you are running. A frequently
used instrument requires, of course, more maintenance than an instrument that is rarely used.
• Column —You may need to replace the column when your performance degrades and
troubleshooting indicates that the column needs maintenance. That may mean that the
end of the column needs to be trimmed or the column needs to be replaced.
• Ion source cartridge —The ion volume and lenses need to be cleaned when they become
dirty.
• Filaments —The filaments need to be replaced when both of them wear out from use.
• Calibration gas reservoir —The calibration gas reservoir needs to be refilled when it gets
empty. Typically, it will need to be refilled every year or two.
• Electron multiplier —The electron multiplier needs to be replaced when the detector
tune (or sensitivity tune on a clean instrument) sets the electron multiplier to a voltage
higher that approaches 3000 V. This component can not be cleaned.
• Foreline pump —The foreline (rough) pump needs an oil change periodically, as
indicated in the pump’s documentation. If you are using a lot of corrosive gases
(ammonia, etc.), you may need to change the oil more often. The foreline pump must be
replaced if it seizes up.
There are many more components of the ISQ 7000 instrument that do not require routine
maintenance, but may need to be replaced in the event that there is a problem with the
instrument. To replace any other component not listed in this chapter, refer to
Chapter 3:
Advanced Troubleshooting.
ATTENTION Si vous utilisez de l’hydrogène comme gaz vecteur, lisez attentivement toutes
les procédures d’entretien avant de les entamer. Tenez compte de tous les avertissements lors
de chaque procédure
Tip You can set up Xcalibur to remind you when some of these components need to be
serviced. See the ISQ 7000 User Manual for information.
