To Replace the 9000 GC/MS Tail
This procedure is necessary if you are switching to a source that requires a
different 9000 GC/MS Tail, replacing a leaking gasket or a contaminated
9000 GC/MS Tail, or separating the 9000 GC from the MSD.
Materials needed
• Gloves, clean, lint-free
• Large (8650-0030)
• Small (8650-0029)
• Tweezers (8710-2460)
• 9000 GC/MS Tail, used with a standard source (G4590-60009)
• 9000 GC/MS Tail, used with a HES (G4590-60109)
• Intuvo gasket, polyimide 5/pk, for temperatures < 350 °C (5190-9072)
• Intuvo gasket, nickel 5/pk, for temperatures 350 °C to 450 °C (5190-9073)
• Intuvo torque driver stored on oven door (5190-9571)
• 7/16-inch open-end wrench
Procedure
1 Vent the MSD (See “To Vent the MSD” on page 136.) When prompted, set
the temperature for the ion source, quads, inlet, detector, column, Guard Chip,
9000 GC/MS Tail, and other components in the flow path heated zones to
< 40 °C.
2 If you are using hydrogen or other flammable gas as a carrier gas, close the
manual gas supply valve to the instrument before turning off the MSD power.
3 Wait until the GC reaches the ready state indicating the components are
cooled below 40 °C before continuing the steps in this procedure.
The inlet, detector, bus components, and column can be hot enough to cause
burns. Cool heated zones to a safe handling temperature before continuing.
Always wear clean gloves while handling any parts that are in the flow path
going to the analyzer or parts that are located inside the analyzer.
