Exhaust venting is important for the following reasons:
It will protect laboratory personnel and the instrument from toxic vapors,
which may be produced by some samples.
It will minimize the effects of room drafts and the laboratory atmosphere on
flame stability.
It will remove heat produced by the flame.
We strongly recommend that you do not place the spectrometer in a chemical
hood. If a chemical hood must be used, make arrangements to prevent
contamination due to corrosive vapors and backdrafts from other hoods.
Do not perform sample preparation in the same hood as the spectrometer.
Space requirements for the spectrometer system
The illustrations on the following pages show the dimensions of the spectrometer
and the space that you require to accommodate the spectrometer, computer, and
ancillary equipment.
Computer and printer
Place the computer near to the spectrometer in a convenient position for working
with both instruments. A movable table, specially designed for a computer and
printer, may be most convenient.
The printer needs to be in a convenient place with enough room for the paper
supply to stand and feed smoothly into the printer.
Accessories
Make sure that there is sufficient room for any accessories near to the
spectrometer.
For example, we recommend that you place the (optional) FIAS flow injection
system on a movable table in front of the atomizer compartment to minimize the
length of the sample transfer tube. Make sure that the wheels of the table can be
securely locked.
