Maintenance and Troubleshooting
60 Agilent 240/280 Series AA (including Zeeman)
and flame shield. If necessary, use a mild detergent to clean the cover. Do
NOT use an abrasive cleaner. When analyzing biological samples, wipe the
instrument with chlorhexidine in 95% ethanol.
Windows
Clean the sample compartment windows and the lamp compartment window with
a gentle stream of filtered air, or a puffer brush, like those used to clean camera
lenses.
If the windows are dirty, wipe them using an optical tissue held between tweezers
and dampened with a 50% ethanol/water solution.
Filters
Check the filter in the air compressor supply line and clean if necessary
(instructions are included with the filter.)
Gas cylinders
Change gas cylinders according to the instructions supplied by the manufacturer.
When changing gas cylinders:
Inspect all gas supply pipes and hoses. Replace any hose showing signs of
damage or deterioration.
Test all connections for leaks using a commercial leak testing solution, a mild
dish washing soap solution, or an electronic leak detector.
Test the operation of all regulators.
Ensure that shut off valves are correctly functioning.
Preventing flashbacks
Instrument and consumable maintenance is important to prevent flashbacks or
unexpected flame events. See the Safety section on Page 22 for detailed
information on how to prevent flashbacks and Page 24 for what to do in the event
of a flashback.
