3. GETTING STARTED
3.1. Unpacking and Initial Setup
CAUTION
The M9110EH weighs about 17 kg (40 pounds) without options installed. To avoid
personal injury, we recommend to use two persons to lift and carry the analyzer.
Inspect the received packages for external shipping damage. If damaged, please advise the
shipper first, then TAI.
Included with your analyzer is a printed record (Form number 04490) of the final performance characterization performed on your instrument at the factory. This record is an
important quality assurance and calibration record for this instrument. It should be placed
in the quality records file for this instrument.
• Carefully remove the top cover of the analyzer and check for internal shipping
damage.
• Remove the set screw located in the top, center of the rear panel.
• Remove the screws fastening the top cover to the unit (four per side).
• Lift the cover straight up.
CAUTION
Printed Circuit Assemblies (PCA) are static sensitive. Electrostatic discharges, too
small to be felt by humans, are large enough to destroy sensitive circuits.
Before touching a PCA, fasten a properly installed grounding strap to your wrist or
touch a bare metal part of the chassis to discharge any electrostatic potentials.
Never disconnect electronic circuit boards, wiring harnesses or electronic
subassemblies while the unit is under power.
Do not position the equipment so that it is difficult to operate the disconnecting
device.
• Inspect the interior of the instrument to make sure all circuit boards and other
components are in good shape and properly seated.
• Check the connectors of the various internal wiring harnesses and pneumatic hoses
to make sure they are firmly and properly seated.
• Verify that all of the optional hardware ordered with the unit has been installed.
These are checked on the paperwork (Form 04490) accompanying the analyzer.
• Once you have determined that no shipping damage exists and the unit includes all
expected hardware options, remove three, red colored shipping screws from the
bottom of the chassis, shown in Figure 3-1.

3.3. Pneumatic Connections
Sample and calibration gases should only come into contact with PTFE (Teflon), FEP, glass
or stainless steel materials. Figure 3-5 and Figure 3-6 illustrate the most common
configurations for gas supply and exhaust lines to the Model 9110EH Analyzer. Appendix D
contains more detailed pneumatic flow diagrams for the analyzer and its various
(pneumatically related) options.
CAUTION
To prevent dust from getting into the analyzer, it was shipped with small plugs
inserted into each of the pneumatic fittings on the rear panel. Make sure that all
dust plugs are removed before attaching exhaust and supply gas lines.
Please refer to Figure 3-3 for pneumatic connections at the rear panel and Table 3-1 for
nomenclature.
Table 3-1: Inlet / Outlet Connector Nomenclature
Rear Panel Label Function
Sample
Exhaust Connects the exhaust of the analyzer with the external vacuum pump.
Span
Zero Air
Connects the sample gas to the analyzer. When operating the analyzer
without zero span option, this is also the inlet for any calibration gases.
On Units with zero/span valve or IZS option installed, this port
connects the external calibration gas to the analyzer.
On Units with zero/span valve or IZS option installed, this port
connects the zero air gas or the zero air cartridge to the analyzer.
• Attach a sample inlet line to the sample inlet port. Ideally, the pressure of the
sample gas should be equal to ambient atmospheric pressure.
• In applications where the sample gas is received from a pressurized manifold, a vent
must be provided to equalize the sample gas with ambient atmospheric pressure
before it enters the analyzer. The vented gas needs to be routed outside the immediate area or shelter surrounding the instrument.
CAUTION
Maximum pressure of any gas at the sample inlet should not exceed 1.5 in-Hg
above ambient pressure and ideally should equal ambient atmospheric pressure.
CAUTION
The exhaust from the external pump needs to be vented outside the
immediate area or shelter surrounding the instrument using a
maximum of 10 meters of 1/4” PTFE tubing.

• Attach the 1/4" exhaust line to the exhaust port of the analyzer and to the inlet port
of the pump.
• Attach zero air and span gas supply lines as appropriate (Figure 3-5 and Figure 3-6)
to the rear panel (Figure 3-3). For this type of analyzer, zero air and span gas are
defined as follows.
3.3.1. Span Gas Defined
Span gas is defined as a gas specifically mixed to match the chemical composition of the
type of gas being measured at near full scale of the desired measurement range. To

Model 9110EH Instruction Manual Getting Started
For example, if the measurement is NOX in ambient air between 0 and 500 ppb, an
appropriate span gas would be NO in air at 400 ppb NO concentration (80% of maximum
range). Even though NO gas in nitrogen could be used as a span gas, the matrix of the
balance gas is different and may cause interference problems or yield incorrect calibrations.
The same applies to gases that contain high concentrations of other compounds (for
example, CO
or H2O). The span gas should match all concentrations of all gases of the
2
measured medium as closely as possible.
Cylinders of calibrated NO gas traceable to NIST-standard reference materials specifications
(also referred to as EPA protocol calibration gases) are commercially available.
Some applications, such as EPA monitoring, require a multipoint calibration where span
gases of different concentrations are needed. We recommend using an NO gas of higher
concentration combined with a gas dilution calibrator such as a T-API Model 700. This type
of calibrator mixes a high concentration gas with zero air (both supplied externally) to
accurately produce span gas of the desired concentration. Linearity profiles can be
automated with this model and run unattended overnight. The dynamic range of the M700
is about 0.1 to 0.001 times the original span concentration.
If a dynamic dilution system such as the TAI model 700 is used to dilute high concentration gas standards to low, ambient concentrations, ensure that the NO concentration of the
reference gas matches the dilution range of the calibrator. Choose the NO gas concentration
such that the dynamic dilution system operates in its mid-range and not at the extremes of
its dilution capabilities. For example, a dilution calibrator with 10-10000 dilution ratio will
not be able to accurately dilute a 5000 ppm NO gas to a final concentration of 500 ppb, as
this would operate at the very extreme dilution setting. A 100 ppm NO gas in nitrogen is
much more suitable to calibrate the M9110EH analyzer (dilution ratio of 222, in the mid-range
of the system’s capabilities).
3.3.2. Zero Gas Defined
Zero air or zero calibration gas is defined as a gas that is similar in chemical composition to
the measured medium but without the gas to be measured by the analyzer, in this case NO
and NO
capable of creating zero air from ambient air. However, if your application is not a
measurement in ambient air, the zero calibration gas should be matched to the matrix of
the measured medium. Pure nitrogen could be used as a zero gas for applications where
NO
For analyzers without zero air options, a zero air generator such as the TAI Model 701 can
be used. Please visit the company website for more information.
If your analyzer is equiped with either the zero/span valve option (Option 50) or the
internal zero/span option (Option 51), the pneumatic connections should be made as shown
in Figure 3-6 (see also Appendix D for detailed diagram).

Once the appropriate pneumatic connections have been made, check all pneumatic fittings
for leaks using the procedures defined in Section 11.5.
WARNING
Gas flow must be maintained at all times for units with IZS Options installed. The
IZS option includes a permeation tube which emits NO2. Insufficient gas flow can
build up NO2 to levels that will damage the instrument. Remove the permeation
device when taking the analyzer out of operation.
