Instrument Cooling Air Supply
The Agilent ICP-OES instrument requires clean, dry, non-corrosive
air for cooling purposes. This is supplied to the instrument through
an air supply vent located at the top, front of the instrument. The
vent is fitted with a dust filter, to filter out particulate matter from
the surrounding environment.
The air supply is used to cool the RF generator and the electronics of
the instrument. Several of these assemblies contain parts prone to
corrosion. The introduction of cooling air contaminated with high
levels of acid vapor or other corrosive substances may cause damage
to the instrument.
Due to the corrosive nature of some analytical work, it is
recommended that in applications demanding high usage of corrosive
materials, an external cooling air supply system be provided. It is
strongly recommended that the cooling air be supplied from an
environmentally controlled area that is away from the instrument
exhaust and any other area where corrosive materials are stored or
used. Do not duct humid, warm air into an instrument in a cooled
laboratory environment.
The external cooling air system with flue, fan, and ducting must
provide a minimum positive flow of 4 m
3
/minute (141 ft
3
/min) to the
instrument when using the External Inlet Duct Adaptor Kit (G8010-
68002). The ducting should be corrosion resistant and fire-proof.
NOTE
If an external cooling air supply system is required, an air inlet duct attachment
must be ordered with the instrument.
After the instrument cooling air supply requirements have been met, check the
checklist box: Cooling air system is set up.
