Static
electricity
Since static electricity can destroy electronic components, your
spectrometer was specially designed to meet the international
standard: IEC 801-2; electrostatic discharge immunity requirements
for industrial process, measurement and control equipment.
If
you
have trouble with static electricity in your laboratory, you can further
protect your spectrometer (especially when you are servicing or
..
handling components inside the spectrometer) by following these
·guidelines:
• Maintain the humidity in the range
of
20% to 80%
noncondensing.
• Use conducting carpet in the work space.

Ventilation
• A void plastic chairs that may build
up
large static potentials.
• Wear natural fiber clothing.
• Use a grounding strap.
There are no special ventilation requirements for an Avatar
spectrometer. The types
of
analysis you plan may require special
ventilation (for example,
if
you will be analyzing highly toxic
samples or dissolving your samples in solvents that interact with
infrared sources). Chlorinated solvents, perfluorochlorinated
solvents, and other solvents containing halogenated hydrocarbons
are often used
as
FT-IR solvents. The pyrolysis
of
these solvents by
an
infrared source may produce hydrochloric acid (HCl),
hydrofluoric acid (HF), or phosgene (COCb).
Hydrochloric acid and hydrofluoric acid are highly corrosive and
may cause accelerated corrosion
of
the metallic components in the
spectrometer
if
the seal on the optical compartment is not properly
maintained or the concentration level of corrosive gasses in the air is
excessively high due to improper sampling techniques.
