1.0 M201A AMMONIA ANALYZER  
This manual is to be used in conjunction with the M200A NOx Analyzer manual p/n  
02246 supplied with this instrument.  
The M201A Ammonia Analyzer consists of a modified M200A Nitrogen Oxides Analyzer  
and M501NH Ammonia Converter:  
A functional block diagram of the system is shown in Figure 1.  
The instrument comes in three pneumatic configurations:  
The basic system is shown in Figure 3;  
The M201A with Z/S valves is shown in Figure 4;  
The M201A with External Calibrator Option (ECO) is shown in Figure 5.  
Figure 2 can be used to connect the M201A system for installation. Please note that for a  
M201A with either a Zero/Span or ECO option, you must connect the umbilical cord,  
02255, between the analyzer and the converter assembly.  
1.1 Principle of Operation  
The Teledyne API Model 201A Analyzer measures ammonia by converting NH3 to nitric  
oxide by the following reaction:  
4NH3 + 5O2 4NO + 6H2O  
The resulting NO is then measured by the chemiluminescent reaction of NO with ozone.  
Consult Section 4.1 in the M200A manual (provided with this instrument) for more  
details on NO measurement.  
A molybdenum converter is continuously in the pneumatic pathway, providing the TN  
channel signal. The M501NH ammonia converter is periodically switched so both  
converters are in series, creating the TNx signal.  
The ammonia concentration is computed by the difference between the TNx and TN  
channels, as shown in the following equation:  
NH3 TNx - TN  
See the pneumatic diagram in Figure 1.  
The actual formula for computation of ammonia concentration is more complicated than  
the above equation, as it includes converter efficiencies, plus sample temperature and  
pressure. The difficulty in ammonia measurement is that the molybdenum converter  
6

Teledyne API Model 201A NH3 Analyzer Instruction Manual, 04689, Rev. B1  
converts some of the ammonia to NO, thus the TN channel data contains a small  
ammonia signal. Secondly, the ammonia converter does not convert all of the ammonia  
or ambient NO2 to NO. Finally, the high temperature in the ammonia converter causes  
the oxygen and nitrogen in ambient air to react, creating a background of NOx which  
needs to be factored into computing the result. Fortunately, all of the above  
shortcomings have been overcome in the M201A by careful calibration, and calculation  
of the result. .  
Periodically, the AutoZero valve switches allowing the analyzer to read zero  
background. The AutoZero readings are subtracted from all of the other readings. This  
improves zero baseline stability.  
As with many chemical reactions the conversion of ammonia in the presence of other  
oxides of nitrogen is complicated.  
In the molybdenum converter operating at 315oC, the following significant reactions are  
taking place:  
Mo + NO2 MoO3 + NO ~100% Eff  
NH3 + Mo + O2 MoO3 + NO <10% Eff  
Notice in the second reaction some of the ammonia is converted to NO by the  
molybdenum metal.  
The M501NH NH3 Converter operates at 825oC. At this high temperature, several  
reactions occur:  
NO NO  
Efficiency = ~100 %  
Efficiency = ~85%  
Efficiency = ~85%  
Efficiency = <1%  
NOx NO  
NH3 NO  
N2 + O2 NO  
As can be seen from the above reactions, the calculation of the ammonia concentration  
and overall calibration of the instrument must be done carefully if accurate ammonia  
concentrations are to be measured. The calibration procedure is covered in Section 2.  
1.1.1 Special Considerations for Ammonia Measurement  
Ammonia is a difficult gas to measure due to its chemical characteristics. Because of  
its large dipole moment, the gas tends to adsorb on surfaces and diffuse into many  
materials. The following precautions should be observed when designing an ammonia  
sampling system and connecting the M201A analyzer to the system:  
Materials:  
Do NOT use TEFLON tubing or fittings in contact with NH3 sample or span gas.  
7

Teledyne API Model 201A NH3 Analyzer Instruction Manual, 04689, Rev. B1  
Do NOT use copper tubing or fittings designed for household plumbing.  
Use ONLY Chromatography grade (cleaned, passivated) stainless steel tubing  
Use ONLY Glass tubing for sample inlet manifold.  
These rules apply also to your calibrator’s internal plumbing. Verify that the calibrator  
pneumatic pathway that contacts ammonia only uses stainless steel or glass tubing.  
The M702SS calibrator supplied with the External Calibration Option is built with  
stainless steel fittings and tubing for all internal plumbing wetted by NH3.  
Typical ambient NH3 levels are < 15 ppb, unless there is some large source of  
ammonia nearby, so the sampling and analysis system must be carefully designed and  
well maintained.  
1.1.2 Sample Filtration  
The M201A does not come with a sample filter installed. Depending on the options  
ordered, a sample filter may be separately packaged with the instrument. If the filter is  
installed, the instrument response time is significantly increased, due to its large surface  
area. Also, the condition of the filter (particulate loading and type) can adversely affect  
the response time.  
For minimum response time operation, the instrument should be supplied with clean  
sample gas at ambient pressure.  
If the sample filter is not included, the only additional filter in the M201A pneumatic  
pathway is a ¼” dia stainless steel sintered filter used to protect the flow control orifice  
from plugging. This filter will plug rapidly if the sample gas is not filtered before entering  
the analyzer. Some means of filtering the sample gas, such as an external stainless  
steel filter should be added upstream of the analyzer.

2.0 CALIBRATION PROCEDURE  
Calibration of the M201A is done by first calibrating the TN and TNx channels with NO  
span gas diluted with zero air. In the second phase of calibration, ammonia span gas is  
introduced to measure the overall system efficiency for NH3 conversion. Unlike NOx  
analysis, the NH3 converter efficiency must be measured because it is considerably  
lower than 100% and may change as the converter ages.  
If the instrument is configured as a basic model, all zero/span gasses are introduced  
through the sample port. If the Zero/Span valves option or the ECO option is ordered,  
the zero/span gas is introduced through the zero/span valves. There are several ways  
of automating the calibration or span check process, they are covered in Section 7 of  
the M200A manual. After reviewing the procedure described below, it should be simple  
to adapt the procedures in Section 7 to the M201A, if necessary.  
2.1 Zero/Span Calibration – Basic Instrument

2.1.2 TN/TNx Channel Calibration Quality  
After the TN and TNx channel calibration it is important to check the slopes and offsets  
to make sure they fall within the acceptable range. The tolerances are different than a  
typical NOx analyzer primarily because of the performance of the M501NH ammonia  
converter.  
Slopes can vary from 2.0 to 0.7, and should be within 20% of each other with the TNx  
slope typically smaller than the TN slope.  
Offsets should be zero ±250 mV and be within 100mV of each other.  
If the slope and offsets are within specifications, proceed on the ammonia channel  
calibration.

2.1.3 NH3 Calibration  
Since the system efficiency is less than 100%, it is necessary to determine a conversion  
efficiency factor for ammonia and enter it into the system.  
1. Set the converter efficiency to 1.0000 by:  
Press CAL-CONC-CONV-SET on the keyboard  
Press the keys under the numbers until 1.0000 appears.  
Press EXIT to return to the sample mode.  
2. Introduce ammonia span gas of known concentration into the instrument. Allow time for  
instrument stabilization. The final readings will be less than the concentration calculated  
from flows. For example with 400 ppb NH3 span gas:  
TN = 40 ppb  
TNx = 380 ppb  
The 40 ppb TN reading is due to the fact that the moly converts a small amount of the  
NH3 gas to NO. The 380 ppb TNx reading is due to ammonia conversion plus some  
conversion of nitrogen and oxygen in the dilution air.  
3. Continuing with the example above, the instrument will report a NH3 concentration value of  
340 ppb. Divide the reported NH3 concentration by the concentration computed from flow  
data.  
NH3 converter eff. = [NH3M201A] / [NH3FLOWS  
From the above example :  
]
M201A NH3 reading = 340 ppb  
NH3 conc from flows = 400 ppb  
340 / 400 = 0.85 NH3 converter system efficiency  
4. This value now is entered into the instrument.  
Press CAL-CONC-CONV-SET  
Press the buttons under the numbers until the desired value is entered, in this case  
0.8500, then press ENTR.  
Press EXIT to return to SAMPLE mode.

The instrument is now fully calibrated.  
2.1.4 Channel Calibration Quality  
After the ammonia channel is calibrated via the converter efficiency parameter, it is  
important to check the calibration by sampling the NH3 calibration gas and confirming  
that the instrument responds with the correct concentration. In the above example the  
M201A should report 400 ppb NH3 concentration when measuring the 400 ppb NH3  
span gas used.

3.0 MAINTENANCE SCHEDULE  
3.1 M201A Maintenance Schedule  
The maintenance requirements of the M201A are essentially like a standard M200A  
NOx analyzer. Please refer to Table 8-1 in the M200A Operator Manual for the M200A  
maintenance schedule.  
In Table 3.1 below, there are the extra maintenance items required by the M201A.

Quarterly as needed  
Section 3.3  
3.2 Maintaining the M501NH Converter  
The M501NH Converter is operated at very high temperature. The center tube in the  
converter slowly oxidizes and requires replacement. The most obvious indicator of  
failure is no ammonia conversion, despite the converter being at temperature. This is  
caused by the oxidized tube breaking off in the converter.  
The following procedure describes how to disassemble and replace converter parts.  
The various parts in the converter become delicate and brittle after prolonged exposure  
to high temperatures. It is therefore a good idea to have a complete set of replacement  
parts on hand before starting, as listed in Table 3.1.

Procedure:  
1. Turn off power to the converter and allow to cool. IT IS VERY IMPORTANT THAT  
THE CONVERTER BE COOL BEFORE ATTEMPTING ANY DISASSEMBLY OR  
REPAIRS.  
CAUTION VERY HOT  
Will cause severe burns – disassembly while hot will  
damage other converter components. Allow sufficient  
time to cool.  
2. Remove the chassis cover of the M501NH, remove the aluminum cover over the  
oven, remove the two U-shaped hold down clamps.  
3. Disconnect the 1 stainless steel and 2 PTFE tubes from the converter cartridge.  
4. Loosen the nut holding the cartridge assembly in the U-shaped angle bracket  
mounted on the chassis floor.  
5. Gently lift and tilt the converter assembly out of the U-shaped bracket and slide the  
assembly out of the oven.  
6. Loosen the ¼” SS tube fitting nearest the hold-down bracket, this fitting holds the  
central tube in the converter. Replace the tube that is part of KIT000191  
7. Re-assemble the converter by doing the above steps in reverse order.

3.3 AutoZero Flow Check  
Since the M201A is an ammonia analyzer, the flow through the AutoZero orifice is  
especially important. Check the AutoZero flow as follows:  
1. This procedure should be performed with the sample pump running.  
2. Fold down the rear panel on the M201A chassis. Locate the vacuum manifold at the  
center rear of the chassis. Locate the 1/8” tube fitting 2nd from the left. It will have a  
label of “0.010”, indicating the flow orifice installed.  
3. Remove the fitting and attach a calibrated flowmeter capable of measuring in the  
range of 500 cc/min. The flowmeter should indicate a flow of 500 cc/min ±10%.  
4. If the flow is outside this range (most likely lower, due to plugging):  
1. Turn off the sample pump and instrument.  
2. Remove the 1/8” pipe-to-tube fitting and remove the ¼” sintered filter (p/n  
FL0001). This filter is meant to protect the orifice, it will usually become plugged and  
need replacement rather than the orifice. Replace the filter, then re-assemble the  
manifold. Re-start the sample pump and re-check the flow.
