Metal Seal Care - Agilent Technologies Helium User Manual

Instructions for Use
Remove O-rings carefully with your fingers. Do not use metal tools for this
CAUTION
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 spectrometer.
• 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.
