How to clean instruments with a fixed
connector interface
You should only clean instruments with a fixed connector interface when it
is absolutely necessary. This is because it is difficult to remove any used
alcohol or filaments from the input of the optical block.
It is important, therefore, to keep dust caps on the equipment at all times,
except when your optical device is in use.
If you do discover filaments or particles, the only way to clean a fixed
connector interface and the input of the optical block is to use compressed
air.
If there are fluids or fat in the connector, please refer the instrument to the
skilled personnel of Agilent’s service team.
How to clean instruments with an optical
glass plate
Some instruments, for example, the optical heads from Agilent
Technologies have an optical glass plate to protect the sensor. Clean this
glass plate in the same way as optical lenses (see “How to clean lenses”
on page 99).
Only use clean, dry compressed air. Make sure that the air is free of
dust, water, and oil. If the air that you use is not clean and dry, this
can lead to filmy deposits or scratches on the surface of your
connector interface. This will degrade the performance of your
transmission system.
Never try to open the instrument and clean the optical block by
yourself, because it is easy to scratch optical components, and
cause them to become misaligned.
