Figure 3-18: Gas Line Connections from Bottled Span Gas – Basic 9110T Configuration
For the 9110T nitrogen oxides analyzer in its basic configuration, attach the following pneumatic lines:
SAMPLE GAS SOURCE
Connect a sample gas line to the SAMPLE inlet
 Use PTFE tubing; minimum OD ¼”
 Sample Gas pressure must equal ambient atmospheric pressure (1.0 psig)
 In applications where the sample gas is received from a pressurized manifold and the analyzer is
not equipped with one of the 9110T’s pressurized span options, a vent must be placed on the
sample gas line. This vent line must be:
 No more than 10 meters long.
 Vented outside the shelter or immediate area surrounding the instrument.
CALIBRATION GAS SOURCES
 CAL GAS & ZERO AIR SOURCES: The source of calibration gas is also attached to the SAMPLE
inlet, but only when a calibration operation is actually being performed.
 Use PTFE tubing; minimum OD ¼”.
