Spectrometer Maintenance Checklists
Maintenance checklists for the spectrometer system are presented below.
General preventative maintenance procedures
Instrument and
work area For safety reasons, and to avoid contaminating new samples, you should make
sure that the instrument and the work area are always absolutely clean. This is
especially important when you are working with toxic substances and when you
are measuring trace amounts of any elements. Wipe up spills immediately
before they can cause further contamination or damage. Before you leave the
instrument standing idle for any period of time, make sure that all the
components are clean.
Fume
ventilation Make sure that the main exhaust ventilation system functions correctly. Always
switch it on when you are using the instrument.
Environmental
conditions Make sure that the environmental conditions are as described in Chapter 2.
Spectrometer, maintenance checklist
External
Surfaces Wipe over the surfaces with a lint-free cloth moistened with a dilute solution of
laboratory detergent. The surfaces are resistant to dilute acids and alkalis, and to
a lesser extent to strong acids and alkalis and organic solvents.
Atomizer
compartment
windows, lamp
end windows These windows do not normally require cleaning but if they become marked,
e.g. with fingerprints, you can clean them with a tuft of cotton moistened with a
dilute solution of isopropanol.
Air filters Replace filter yearly or more often in a dusty environment.
