Tubing (optional)
Sample and exhaust tubing calculations
This table shows the flow rate, tubing length, transport time, and maximum
pressure and vacuum at the inlet and exhaust points�
Tubing lengths vary among gases� If the pressure or vacuum on the inlet/exhaust
lines does not meet the recommended values, the detector may encounter flow
faults�
Description
Tubing length, m (ft)
Transport time (sec)
Flow rate (cc/min.)
Inlet
Tubing OD in mm (in.)
Tubing ID in mm (in.)
Tubing Length, m (ft)
Outlet Tubing OD, mm (in)
Tubing ID, mm (in)
The overall maximum load on the pump between the inlet and the exhaust should not exceed 10 inches H
NOTE
Use Teflon Fluorinated Ethylene Polymer (FEP) tubing to ensure proper sample
transport�
Optional external filters can be installed to reduce noise or to monitor for gas at
the location of the detector� To do this an inline filter is simply connected to the
gas inlet port� The area around the detector is then being monitored as opposed
to a sample being drawn from a remote location�
