O-ring Care
When removing, checking or replacing O-rings, keep in mind the following:
NOTE
Varian recommends replacing all O-rings during routine maintenance or during any
maintenance procedure requiring that O-rings be removed.
CAUTION
Remove O-rings carefully with your fingers. Do not use metal tools for this task; this
prevents scratching of any sealing surfaces.
• Wipe all O-rings clean with a lint-free cloth before installation to ensure that no
foreign matter is present to impair the seal.
• Do not use grease or any other substance on O-rings that will come in contact
with the vacuum surfaces.
• Do not use alcohol, methanol or other solvents on O-rings. Doing so causes
deterioration and reduces their ability to hold a vacuum.
• Varian does not recommend the use of vacuum grease. If applicable, apply a
small amount of Apiezon
®
L grease and wipe the O-rings shiny dry.
Metal Seal Care
CAUTION
Metal Seals must be replaced any time a spectrometer is opened. All fasteners must
be installed and torqued per assembly procedure specifications. Remove Metal
Seals carefully with your fingers or a soft tool. Metal tools scratch sealing surfaces.
• Metal Seals are supplied in pre-cleaned condition. No cleaning is required. If
necessary, Metal Seals can be cleaned using the recommended solvents. Wipe
Metal Seals clean with a lint-free cloth before installation to ensure that no for-
eign matter impairs the seal.
• Do not use grease or any other substance on Metal Seals that will come in con-
tact with the spectrometer.
Spectrometer
CAUTION
Store the Ion Source/Preamplifier sub-assembly in a cool, dry area in a tightly
sealed, ESD protected container. Wear non-powdered, ESD-safe Nitride or
equivalent gloves when handling the spectrometer. Wash hands thoroughly after
handling the spectrometer filaments and especially before smoking or eating.
The spectrometer and PCB’s are static sensitive devices. Wear a grounding strap
when performing any maintenance on these units and especially when performing
maintenance of static sensitive parts.
CAUTION
The spectrometer operates at a very high vacuum produced by the high vacuum
turbomolecular pump. Service of the spectrometer requires that this vacuum be
vented to the atmosphere.
