To Remove the 7010 Series CI Source
Materials needed
• Gloves, clean, lint-free (Large 8650-0030) (Small 8650-0029)
• Tweezers (8710-2460)
Procedure
1 Vent the MS. (See “To Vent the MS” on page 124.)
2 Open the analyzer chamber. (See “To Open the Front Analyzer Chamber” on
page 156.)
3 Disconnect the wires from the ion source. (See“To Connect or Disconnect
7010 Series CI Source Wiring” on page 217.)
4 Remove the two large thumbscrews that hold the ion source in place.
5 Pull the ion source out of the source radiator, and place it in its storage
container.
The analyzers, GC/MS interface, and other components in the analyzer
chamber operate at very high temperatures. Do not touch any part until you
are sure it is cool.
Always wear clean gloves to prevent contamination when working in the
analyzer chamber.
Use an antistatic wrist strap, and take other antistatic precautions before
touching analyzer components.
When disconnecting leads, pull on the connectors, not on the wires.
