than a comparable length of flexible ducting. When smooth stainless-steel is used,
elbows must be used to turn corners. These elbows should turn at a center line radius
of 150 mm with a maximum bend angle of 45 degrees to reduce friction losses, and
the number of elbows should be minimized.
Additional recommendations on the venting system include:
•
Make sure duct casing is installed using fireproof construction. Route ducts
away from sprinkler heads.
•
Locate the blower as close to the discharge outlet as possible. All joints on the
discharge side should be airtight, especially if toxic vapors are being carried.
•
Equip the outlet end of the system with a back draft damper and take the
necessary precautions to keep the exhaust outlet away from open windows or
inlet vents and to extend it above the roof of the building for proper dispersal of
the exhaust.
•
Equip the exhaust end of the system with an exhaust stack to improve the overall
efficiency of the system.
•
Make sure the length of the duct that enters into the blower is a straight length at
least ten times the duct diameter. An elbow entrance into the blower inlet causes
a loss in efficiency.
•
Provide make-up air in the same quantity as is exhausted by the system. An
"airtight" lab will cause an efficiency loss in the exhaust system.
•
Ensure that the system is drawing properly by using an air flow meter.
•
Equip the blower with a pilot light located near the instrument to indicate to the
operator when the blower is on.
The venting system for the ICP torch should be positioned over the Torch
Compartment Chimney located on top of the sample compartment. For proper
instrument venting, order PerkinElmer Venting Kit (Part No. 03030447 Kit for 115
V or Part No. 03030448 Kit for 230 V) by contacting your PerkinElmer sales
representative. The minimum distance from the top of the instrument’s Torch
Compartment Chimney to the bottom of the extraction vent should be 7.5-12.5 cm.
(3-5 in.). Gas, water, and air lines of 6 m (20 ft.) are also provided. Figure 2-1 shows
the location of the ICP torch exhaust vent.
