Agilent 55B AA Spectrometer User's Guide
The standard plastic laboratory tubing supplied with your instrument is not
suitable for draining organic solvents or venting organic vapors.
If organic or toxic solutions are being used in the spray chamber, vent tubing
must be connected to the vapor vent on the liquid trap and led to an active
exhaust system. Do not lead the vapor tube to the waste vessel.
If you are not using toxic or hazardous liquids in the spray chamber, leave the
vapor vent uncovered.
Use small, wide-necked waste vessels and empty them frequently—do not
accumulate large volumes of flammable solvent.
Do not use glass waste vessels—use vessels made of a material that will not
shatter in the event of a flashback. Metal vessels will corrode and are difficult
to determine the level of liquid in them.
Ensure that your waste vessel is below the instrument and located in an open,
well-ventilated position where you can see it. Never locate the vessel in a
confined space. When your analytical program has been completed, or at the
end of the working day, always empty the waste vessel.
When your analytical program has been completed, or at the end of the
working day, always empty and clean the liquid trap.
Do not mix nitric or perchloric acid residues with organic solvent residues.
Keep the burner slot, spray chamber and liquid trap clean.
Always use the internal igniter to light the flame as its operation indicates that
all the safety interlocks are satisfied. Do not attempt to bypass these safety
interlocks.
