1.2.4 Metal Seal Care

CAUTION
Manual 699910005, Hot Ion Source Replacement
Agilent recommends replacing all O-rings during routine maintenance or
during any maintenance procedure requiring that O-rings be removed.
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.
Agilent 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 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 foreign matter impairs
the seal.
Do not use grease or any other substance on Metal Seals that
•
will come in contact with the spectrometer.
