Maintenance 4
Agilent 7500 Series ICP-MS Hardware Manual 4-5
Checking Lab Conditions
You must maintain the environmental conditions required by the Agilent 7500
which were established during installation, because they can affect both safety
and instrument performance. For additional information, refer to the Chapter
2 and the Agilent 7500 Series ICP- MS Site Preparation Guide.
Maintenance Clocks
Use the MassHunter Workstation (or ChemStation) software to help determine
your maintenance schedule.
The Running time dialog box can display messages to notify you of the
maintenance schedule such as changing the rotary pump oil, cleaning the ion
lenses, etc. MassHunter Workstation (or ChemStation) generates messages
based on the total time of plasma ignition, vacuum operation and the lapse of
time.
Check the following items:
• Cumulative time for power ON
• Cumulative time for vacuum ON
• Cumulative time for plasma ON
• Cumulative ion count for the electron multiplier (EM)
• Cumulative operation time for rotary pump
• Cumulative operation time for turbo pump
• A lapse of time after maintenance and resetting the operation time
