Exhaust System
The plasma operates at a temperature of approximately 7,500 °C,
(13,500 °F) with up to 1,500 watts of RF energy. Sample
compartment exhaust fumes can be noxious or corrosive.
The Agilent ICP-OES must be located under a flue that is vented by
an exhaust fan and ducted to an external vent. The exhaust system
with flue, ducting and external vent must provide a minimum flow of
2.5 m
3
/min (88 ft
3
/min) at 2.4 m/s (7.7 ft/s) and a maximum flow of
6.0 m
3
/min (212 ft
3
/min) at 5.7 m/s (18.6 ft/s).
The exhaust system installation must comply with any rules and/or
regulations that may be imposed by the local authorities responsible
for control of facilities and fixtures in the work place.
The exhaust fan should be located at least 2 meters (6 ft, 6 in) away
from the top of the instrument chimney. The fan control switch and
running indicator lamp should be located in a position where the
instrument operator can view the indicator and access the control
switch.
Ducting must be corrosion-resistant, fire-proof and should be kept
clear of fire alarms, sprinkler heads and other heat sensitive devices.
The external vent must be fitted with a back draft damper and the
outlet location must be clear of doors, windows and heater or air-
conditioning units.
