Instrument Maintenance Checklist
CAUTION
Flame should be turned off while performing the instrument
maintenance checklist.
To properly maintain the spectrometer instrument, do the following as required:
•
Clean the exterior of the instrument.
•
Inspect and clean any fans and filters.
•
Monitor tank pressures
•
Inspect the burner assembly (see checklist later in this chapter).
•
Inspect the drain system.
•
Optical: Check the window surfaces in the sample compartment for fingerprints, dirt, lint, etc.
Clean the windows with a tuft of cotton moistened with a dilute solution of isopropanol followed
by several rinsing with deionized water.
•
If the energy of the primary source lamp is too low, refer to the lamp troubleshooting information
in the Troubleshooting chapter of this manual. The lamp may need to be realigned, or replaced if
it is old.
•
If the intensity of the deuterium arc background corrector source is too low, refer to the
troubleshooting information in the Troubleshooting chapter of this manual. The background
corrector source lamp may need to be realigned or replaced.
•
Normally, the spectrometer optics will require little or no maintenance. However, low energy
lamp readings, or noisy or erratic results may indicate that the optics require cleaning or
alignment. This should only be done by a PerkinElmer service engineer.
•
A service technician may clean the mirrors by careful use of a clean cotton cloth moistened with a
clean solvent such as alcohol. Quick drying of the surfaces is important. Do not rub optical
surfaces.
CAUTION
If mirror surfaces become dirty (e.g., from exposure to
laboratory vapors), cleaning should be done only by a
PerkinElmer service engineer.
If a service engineer is not available,
a skilled technician may clean the surfaces as described above.
Special care must be taken to avoid scratches which would require
replacement of the mirrors.
