Spectrometer maintenance procedures
Procedures described
Cleaning the windows.
Changing the air filters.
Resetting the circuit breaker and changing the fuses.
Replacing the deuterium lamp.
Cleaning the windows of the optical system
Caution
Risk of damage to optical components
Never touch or clean the surfaces of the grating or mirrors.
If mirror surfaces are scratched they must be resurfaced.
Do not allow cleaning fluids to come into contact with any of the reflecting
surfaces.
Most of the optical components are under the main cover of the spectrometer and
are protected by the black optics covers.
Usually these components require no maintenance, provided the laboratory fume
ventilation system is working correctly and the environmental conditions are as
described in Chapter 6, Laboratory Requirements.
The only optical parts that are exposed are:
The atomizer compartment windows.
The windows of the lamps.
The furnace windows. Cleaning the furnace windows is described under
System Maintenance in the Graphite Furnace User's Guide.
These windows are important parts of the whole optical system. Handle them
carefully, as you would any sensitive optical component. Do not directly touch the
windows.
If mirror surfaces need cleaning, this must be done by a PerkinElmer service
engineer or a similarly authorized and trained person who knows the special
techniques required.
