To Open the Front Analyzer Chamber
The front analyzer chamber should only be opened to clean or replace the ion
source, or to change a filament.
Materials needed
• Gloves, clean, lint-free (Large 8650-0030) (Small 8650-0029)
• Wrist strap, antistatic
• Small (9300-0969)
• Medium (9300-1257)
• Large (9300-0970)
Procedure
1 Vent the MS. (See “Venting the MS” on page 105.)
2 Open the left side panel. (See “To Open Left Side Panel for Access to the
Analyzer Chambers” on page 119.)
3 Loosen the front analyzer side plate thumbscrews if they are fastened. (See
Figure 47 on page 158.)
Electrostatic discharges to analyzer components are conducted to the quad
driver board, where they can damage sensitive components. Wear a grounded
antistatic wrist strap, and take other antistatic precautions before you open the
analyzer chamber. (See “Electrostatic discharge” on page 151.)
The analyzer, 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.
