Caustic agents

Volatile solvents

containing
halogenated
hydrocarbons
Thermo Fisher Scientific
Components may be degraded by exposure to caustic agents or their
vapors. To maintain the instrument in safe working condition, avoid
caustic agents. Damage caused by caustic agents is not covered by
warranty.
If you use volatile solvents regularly, purging the instrument with clean,
dried air or nitrogen is strongly recommended. Damage caused by
volatile solvents is not covered by warranty. Also, to avoid fire or
explosion:
•
Do not leave exposed solvents near, in, or on the instrument longer
than necessary.
•
Use sealed sample cells.
These measures help prolong the life of your instrument and can eliminate
spectral interference caused by volatile solvent vapors.
Danger Prevent fire and explosion. The infrared source inside the instrument is an
ignition source. If you are using volatile solvents, provide a fume hood or
other active venting system that is free of spark and other ignition sources
and prevents flammable vapors from collecting in the atmosphere
surrounding the instrument.
Solvents
Chlorinated solvents, perfluorochlorinated solvents, and other materials
containing halogenated hydrocarbons are often used as FT-NIR solvents.
The pyrolysis of these solvents by a near-infrared source may produce
hydrochloric acid (HCl), hydrofluoric acid (HF), or phosgene (COCl2).
Hydrochloric acid and hydrofluoric acid are highly corrosive and may cause
accelerated corrosion of the metallic components in the instrument 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.
Warning Hydrochloric acid, hydrofluoric acid and phosgene are highly toxic and
reactive . If you plan to regularly use solvents containing halogenated
hydrocarbons, be sure your work area is properly ventilated and maintain
appropriate safety practices.
Solvents containing halogenated hydrocarbons should not be left in or on
any of the sampling modules longer than necessary.
