Maintaining the Vacuum System
Periodic maintenance
Some maintenance tasks for the vacuum system must be performed
periodically. (See
on page 148.) These include:
•
Checking the foreline pump fluid (every week)
•
Checking the calibration vial(s) (every 6 months)
•
Replacing the foreline pump oil (every 6 months or as needed)
•
Tightening the foreline pump oil box screws (first oil change after installation)
•
Replacing the foreline pump (typically, every 3 years)
•
Replacing the tip seals in the optional dry scroll pump (every year)
•
Checking the system for leaks (On a monthly basis for safety, or as needed
depending upon the type of gases being used in the lab.)
Failure to perform these tasks as scheduled can result in decreased instrument
performance. It can also result in damage to your instrument.
Other procedures
Tasks such as replacing an ion vacuum gauge should be performed only when
needed. Refer the
Agilent 7000/7010 Series Triple Quad GC/MS Troubleshooting
and Maintenance Manual
and the online help in the MassHunter WorkStation
software for symptoms that indicate this type of maintenance is required.
