1.0 T201 AMMONIA ANALYZER  
This manual is to be used in conjunction with the T200 NOx Analyzer  
manual, p/n 06858 supplied with this instrument. It is important that you  
familiarize yourself with the workings of the NOx analyzer before  
proceeding with NH3 measurements.  
The T201 ammonia analyzer consists of a modified T200 nitrogen oxide  
analyzer and an M501 NH3 ammonia converter. The analyzer measures  
the following individual gas concentrations: TNx (NH3 and NOx), NOx  
(NO and NO2) and NO in the sample gas.  
The ammonia concentration is calculated by subtracting the NOX  
reading from the TNx measurement.  
The nitrogen dioxide concentration is calculated by subtracting the NO  
reading from the NOx measurement.  
The instrument comes in three pneumatic configurations:  
The T201 with External Calibrator Option (ECO) is shown in  
The basic system is shown in Figure 1-2.  
The T201 with Zero/Span valves is shown in Figure 1-3.  
Note  
For a T201 analyzer with Zero/Span option you must connect the umbilical  
cord P/N 02255 between the analyzer and the external M501 NH3 converter  
assembly.  
If the analyzer is purchased without the Zero/Span option then the zero and  
span calibration gases must be individually applied to the Sample port.  
Remember, the gases must be clean/dry and supplied at ambient pressure.  
CAUTION  
Do not pressurize the Sample/Span/Zero port above ambient

T201 Ammonia Analyzer  
Teledyne API Model T201 NH3 Analyzer Operator Manual  
1.1 THEORY OF OPERATION  
The Teledyne-API Model T201 analyzer measures ammonia by oxidizing  
it to nitric oxide by the following reaction:  
4NH3 + 5O2 4NO + 6H2O  
The resulting nitric oxide is then measured by the chemiluminescent  
reaction with ozone. Consult Section 10.1 in the T200 manual (provided  
with this instrument) for more details on the nitric oxide measurement.  
The analyzer uses two converters to oxidize the different sample gases. A  
high temperature catalytic converter, the M501 NH3, converts NH3 and  
NOx into NO creating the TNx channel. A second converter, housed inside  
the T201 analyzer and consisting of heated molybdenum, converts all of  
the NOx in the sample to NO producing the NOx channel. The nitric oxide  
channel is measured while bypassing both the M501 NH3 and  
molybdenum converter. A Nafion® drier operated in reflux mode, is  
installed prior to the molybdenum converter and the AutoZero valve. The  
drier removes ammonia and water from the switched stream. The  
ammonia would have otherwise been converted by the molybdenum and  
registered as NOx. This location provides the drier with continuous flow,  
thereby allowing it to stabilize faster.  
Note  
Due to the Nafion® drier, the analyzer has a maximum ammonia range of  
2.0 PPM.  
The calculated gas concentrations, ammonia and nitrogen dioxide, are  
computed from the differences between the measured channels, as  
outlined in the following equations:  
NO (Nitric Oxide) Concentration = Measured  
TNx (Total Nitrogen) Concentration = Measured (NH3 + NO2 + NO)  
NOx (Total Nitrogen – Ammonia) Concentration =  
Measured  
(NO2 + NO)  
NH3 (Ammonia) Concentration = Calculated as follows:  
[(TNx - NOx) / (NH3_CE_FACTOR1)]  
NO2 (Nitrogen Dioxide) Concentration = Calculated as follows:  
[(NOx – NO) / (NO2_CE_FACTOR1)]  
Note  
The nitrogen dioxide efficiency factor (NO2_CE_FACTOR1) must be  
calculated by conducting a GPT (gas phase titration) as described in Section  
8.3.3 of the T200 manual and Section 6.0 of this manual. This value gives a  
good indication of how well the molybdenum is converting nitrogen dioxide  
into nitric oxide. In a properly functioning analyzer the value should be close  
to 1.0. It is recommended that the molybdenum efficiency be checked every  
three months.

Teledyne API Model T201 NH3 Analyzer Operator Manual  
T201 Ammonia Analyzer  
The ammonia converter efficiency factor (NH3_CE_FACTOR1) is  
discussed in more detail in Section 2.3 of this manual. The conversion  
efficiency of the M501 NH3 should be checked prior to starting long term  
tests. Both efficiency factors can be accessed through the analyzer VARS  
MENU.  
The actual formula for computation of the gas concentrations is more  
complicated than the above equations, as it includes sample, reaction cell  
pressure changes and averaging the PMT signal. Then the zero offset and  
slopes are applied to the separate channels (TNx, NOx, NO) to determine  
the concentrations. Concentration compensation occurs while the variable  
TP_FACTOR under the VARS MENU is switched ON. Otherwise the  
displayed concentration is uncompensated. It is recommended that  
the variable TP_FACTOR remain on at all times.  
1.1.1  
1.1.2  
Minimizing PMT Drift  
In order to account for PMT drift in the analyzer, the AutoZero valve  
switches once a minute allowing the analyzer to read zero background.  
The AutoZero valve directs the sample gas stream to completely bypass  
the reaction cell, while simultaneously filling the reaction cell with Ozone  
for dark noise measurement. This is then subtracted as a measurement  
offset from the raw PMT concentration signal. This process improves zero  
baseline stability by minimizing the effect of PMT sensor drift.  
Purging the Reaction Cell  
As with many chemical reactions the conversion of ammonia in the  
presence of other oxides of nitrogen is complicated. It is important to note  
that the valve DWELL time for an AZERO measurement has a default  
setting of 8 seconds. Shortening this value may not allow enough time to  
properly purge the reaction cell of excess nitric oxide from the previous  
measurements.  
In the molybdenum converter operating at 315oC the following significant  
reactions are taking place:  
Mo + NO2 MoO3 + NO ~100% Efficiency  
The M501 NH3 ammonia converter operates at 825oC. At this high  
temperature, several reactions occur:  
NO NO  
NO2 NO  
NH3 NO  
NH3 NO2  
Loss = ~ 3%  
Efficiency = ~97%  
Efficiency = ~97%  
Efficiency = ~5%

T201 Ammonia Analyzer  
Teledyne API Model T201 NH3 Analyzer Operator Manual  
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.  
1.2 SPECIAL CONSIDERATIONS FOR AMMONIA MEASUREMENT  
Ammonia is a difficult gas to measure due to its chemical characteristics.  
The gas tends to adsorb onto surfaces and diffuse into many materials. The  
following precautions should be observed when designing ammonia  
sampling systems and connecting them to the T201 analyzer:  
Do NOT use copper tubing or fittings designed for household plumbing.  
Use ONLY Chromatography grade (cleaned, passivated) stainless steel  
tubing.  
Use ONLY glass for sample inlet manifold.  
ALWAYS keep the tubing from the M702SS calibrator to the analyzer  
as short as possible. USE stainless steel tubing throughout, especially  
from the ammonia calibration bottle to the calibrator.  
If possible HEAT the sample line and DRY the sample gas.  
Sample filters will cause response delays on both the rise and fall of the  
sample signal.  
These rules apply also to your calibrator’s internal plumbing. It is highly  
recommended that you use a M702SS calibrator in conjunction with the  
T201. The calibrator has stainless steel plumbing throughout. The T700  
calibrator contains Teflon tubing and internal MFC’s that can be affected by  
the ammonia gas, therefore, the T700 calibrator is not recommend for use  
with the T201 analyzer. It is important to keep the sampling system well  
maintained.  
1.3 SAMPLE FILTRATION  
The instrument can be provided with an optional stainless steel sample  
filter P/N 05571. For minimum response time operation, the instrument  
should be supplied with clean sample gas at ambient pressure.  
An additional filter resides in the T201 pneumatic pathway. The filter is a  
¼” diameter stainless steel sintered filter used to protect the reaction cell  
flow control orifice from plugging. This filter will plug rapidly if  
contaminated sample gas is not filtered before entering the analyzer.  
Note  
In situations where the sample gas is known to be contaminated with  
particulate material, it is advisably to add extra filtration. However, it must be  
noted that the response time is directly extended through filter additions.

2.0 CALIBRATION PROCEDURE  
This section begins with a high-level overview of the calibration procedure  
for the T201 analyzer. Details are provided starting in Section 2.1.  
First, take the time to read the T200 manual to familiarize yourself with  
the Chemiluminescence process. It is important to remember that the  
analyzer is merely measuring different levels of nitric oxide sample gas  
on three separate channels (TNx, NOx, NO). The ammonia and nitrogen  
dioxide concentrations are then calculated using this information.  
Assemble the T201 analyzer according to the pneumatic configurations  
outlined in Figure 1-1. Remember: DO NOT pressurize the sample,  
span or zero ports (Zero/SPAN valves are optional) during calibration.  
Allow the analyzer to pull the gas through the system using the vacuum  
pump.  
CAUTION!  
If the presence of ozone is detected at any time, call Teledyne API  
Customer Service as soon as possible:  
800-324-5190 or email: [email protected]  
Next, zero the analyzer using an approved zero air source, such as,  
bottled zero air, nitrogen or zero air generated by a Teledyne-API M701  
zero air source. This sets the zero offset for the three individual  
channels (TNx_OFFS, NOx_OFFS, NO_OFFS). Confirm that all  
displayed concentrations read zero.  
Span the analyzer using bottled nitric oxide gas diluted to a level set to  
80% of the expected sample range, preferably using a M702SS  
Calibrator. This sets the slope for the three individual channels  
(TNx_SLOPE, NOx_SLOPE, NO_SLOPE). Confirm that displayed  
concentrations TNx , NOx and NO display the correct span concentration.  
If you haven’t done so recently, conduct a GPT (gas phase titration)  
and confirm the molybdenum is functioning accordingly. Section 8.3.3  
of the T200 manual outlines the GPT procedure. Section 6.0 of this  
manual consists of a service note for checking the molybdenum  
converter. There should be no reason to adjust the molybdenum  
efficiency factor on a new analyzer. If a diluted bottled of nitrogen  
dioxide gas is used to determine the molybdenum efficiency, allow  
enough time for the span value to stabilize. Nitrogen dioxide exhibits  
similar hold up issues as ammonia gas. Therefore, it may take a  
number of hours before the NOx reading stabilizes.  
Span the analyzer using bottled ammonia gas diluted to a level set to  
80% of the expected sample range, preferably using a M702SS Calibrator.  
Note  
The first time bottled ammonia is connected to the gas dilution system,  
regulator/calibrator, the TNx reading may take a number of hours to stabilize.

Calibration Procedure  
Teledyne API Model T201 NH3 Analyzer Operator Manual  
2.1 ZEROING THE ANALYZER  
The analyzer can be zeroed by either applying zero air straight to the  
sample port or through the optional Zero/Span valves, if installed. It is  
important to remember that if the analyzer was previously sampling  
ammonia gas, prior to conducting a Zero calibration, it will take some  
period of time before the zero baseline is reached. The process of zeroing  
the analyzer consists of delivering dry zero air to the analyzer. The  
operator then manually zeros the TNx and NOx channels individually  
through the user interface. The following Tables outline the steps  
necessary to zero the analyzer.

5.  
NH3 STB Reading Wait for the displayed stability reading to fall below  
1.0 PPB. The lower the stability reading the better the  
zero value.  
Press ZERO  
If you change your mind after pressing ZERO, you  
can still press EXIT without zeroing the instrument.  
You don’t have to enter concentration values. The  
analyzer knows to apply 0 PPB.

Press CALZ  
The T201 enters the calibrate mode from sample  
mode. The zero gas is supplied through the ZERO  
inlet port on the rear panel of the M501 NH3.  
Table 2.1  
Follow Steps 2 to 8 in Table 2-1.  
Notes  
Since the zero gas concentration is defined as 0 ppb, it is not necessary  
to enter the expected concentration values.  
Both the TNx and NOx channels must be zeroed individually. When you  
zero the NOx channel both the offsets for NOx and NO are configured.  
All readings should display zero following this action.  
It is recommended that the calibration of both the TNx and NOx channels  
be done at one time.  
Always confirm that excess zero air is flowing past the sample or zero  
port, if the Zero/Span option is present, on the rear of the M501 NH3  
converter. There should always be some excess flow. If insufficient flow  
is supplied to the analyzer ambient gas will be entrained and the zero  
offset values will be incorrect. However, it is important not to over  
pressurize the analyzer.  
It is a good idea to allow the analyzer to sample zero gas for extended  
periods following zero calibration. Large drifts can signify leaks or  
indicate an issue with the zero air source.  
2.2 SPANNING THE ANALYZER WITH NITRIC OXIDE GAS  
The analyzer can be spanned by either applying nitric oxide gas straight to  
the Sample port or through the Zero/Span valve option, if installed. It is  
important to remember that if the analyzer was previously sampling  
ammonia gas, prior to conducting a nitric oxide span calibration, it will  
take some period of time before the TNx channel stabilizes. The process of  
spanning the analyzer consists of diluting bottled gas, using a calibrator  
and delivering to the analyzer. The operator then manually spans the TNx  
and NOx channels individually through the user interface. The following  
Tables outline the manual steps necessary to span the analyzer.

Follow Steps 2 to 5 in Table 2-3.  
Notes  
Both the TNx and NOx channels must be spanned individually with nitric  
oxide gas. When you span the NOx channel both the NO and NOx  
concentrations must be manually inputted.  
It is recommended that the calibration of both the TNx and NOx  
channels be done at the same time.  
Always confirm that SPAN gas is flowing past the sample or span port  
on the rear of the M501 NH3 converter. There should always be some  
excess flow. If insufficient flow is supplied to the analyzer ambient gas  
will be entrained and the span values will be incorrect. However, it is  
important not to over pressurize the analyzer.  
It is a good idea to allow the analyzer to sample span gas for extended  
periods following span calibration. Large drifts can signify leaks or  
indicate an issue with the span gas source.  
If after spanning with nitric oxide, the analyzer slopes are out of range  
conduct the following:  
- Confirm the gas sources are good. Usually the bottle is certified to a  
known level of nitric oxide. The bottle should be balanced with nitrogen.  
- Try not to use the same regulator for nitric oxide as was used on  
ammonia. This also holds for the tubing between the different bottles  
and the mixing source (calibrator).  
- Confirm the zero reading is good by delivering Zero gas.  
- Confirm that the concentration delivered to the analyzer is equal to  
what you entered under the CONC menu NOx and TNx.  
- Leak check both the M501 NH3 and analyzer together.  
- Using section 11.6.5 of the T200 manual confirm that the PMT sensor  
hardware calibration is set correctly.

Calibration Procedure  
Teledyne API Model T201 NH3 Analyzer Operator Manual  
The most important criterion an individual can avail themselves of when  
spanning an analyzer with ammonia gas is “patience”. Ammonia is a very  
sticky gas and the response of the analyzer/calibration system depends on  
a number of factors. The following lists some important points the user  
should be aware of when calibrating:  
Is this the first time the analyzer/calibration system has seen  
ammonia gas in the last couple of days? If so, spanning to a  
fixed value will take considerably longer than normal: possibly  
12 hours to completely stabilize.  
Is the tubing that is delivering span gas from the calibration  
bottles, made of stainless steel? Is the tubing from the rear of  
the calibrator to the analyzer, made of stainless steel? Where  
possible use stainless steel tubing.  
Note  
The operator is responsible for delivering a set amount of ammonia to the  
analyzer, calculating the converter efficiency of the M501 NH3 and entering  
the efficiency value through the user interface, if required.  
Is the environment where the analyzer resides undergoing large  
temperature swings (+/- 5 oC about the norm temperature)? If so  
the sample line can absorb and desorb ammonia at  
concentration rates that are distinguishable to the analyzer. If  
possible, heat the sample line to a constant maximum ambient  
temperature.  
Does the sampling environment contain large amounts of  
particulates? If so, it may be necessary to add the sampling filter  
option. As outlined previously, this will affect the analyzer  
response.  
One method to increase the response of both the sampling  
system and the analyzer is to flow a larger concentration of  
ammonia gas through the pneumatics for a couple of hours. For  
example, if the expected range is 500 PPB of ammonia, then  
flowing 1000 PPB will speed up the absorption which occurs  
throughout the pneumatics. The long delays in ammonia  
response occur when the analyzer hasn’t sampled the gas for  
some time. Ammonia desorbs from the pneumatics, these  
surfaces need to be rewetted before span stability is achieved.  
Prior to conducting the ammonia calibration, confirm that the  
ammonia converter efficiency is initially set to 1.000 using the  
following menu key selections:

error, it may not be necessary to change the efficiency factor from 1.00.  
Therefore, calibration with nitric oxide gas is all that is required.

3.0 CONFIGURABLE ANALOG OUTPUT OVERVIEW  
There are three different methods to extract concentration data from the  
analyzer: internal data acquisition system (DAS), hyperlink, or strip chart.  
DAS  
The user can set up an internal DAS configuration either through the user  
display or using TAPI’s windows based software called APICOM. The  
analyzer stores data internally, which is available later for download  
through the RS-232 or Ethernet port.  
Hyperlink  
The user sends text based commands to retrieve data through the RS-232  
port.  
Strip Chart  
The user interfaces a strip chart recorder and/or data-logger to the four  
analyzer analog output channels of the rear panel Analog Out connector  
(Figure 3-1). Table 3-1 presents the default configurations of the analog  
outputs, and Table 3-2 shows the Pin-outs for these four channels.

Note  
In actuality the analog output configuration of the analyzer may be different  
than stated above. The outputs can be configured differently at the factory  
depending on whether they were assigned during the procurement of the  
product. It is possible to check the configuration of the analyzer by accessing  
the ANALOG I/O CONFIGURATION through the DIAG menu.  
The analyzer operates in Dual Mode during gas detection. This means each  
of the measured concentrations can have two separate slopes and offsets,  
one for the low range and one for the high range. Though uncommon, a user  
may decide to calibrate the analyzer with nitric oxide at, for example, 100  
PPB using the LOW range and then perform another calibration at 450 PPB  
using the HIGH range. Through the analog outputs the user can then assign  
analog output A1 to TNxCNC1 and output A2 to TNxCNC2. Gases with the  
“1” designation use the slope and offset for the LOW range, while gases  
with the “2” designation will use the slope and offset for the HIGH range. It  
is recommended that both the LOW and HIGH ranges be calibrated at the  
same time. Independent of whether the HIGH range is actually being  
outputted to the analog outputs.  
For analog output configuration, signal type and range selection and  
calibration, use the T200 manual.

4.0 MAINTENANCE SCHEDULE  
The maintenance requirements of the T201 are the same as a standard  
T200 NOx analyzer but with additional maintenance items (Table 4-1).  
Please refer to Section 13 in the T200 Operator Manual for the T200  
maintenance schedule and for maintenance and repair procedures.  
The T201 requires the following additional maintenance items.  
Table 4-1. Preventative Maintenance Schedule

Section 9.3.9 T200 Manual  
4.1 M501 NH3 MAINTENANCE  
The M501 NH3 external converter is operated at 825 ºCelsius. Because of  
this the stainless steel ¼” tube internal to the converter slowly oxidizes  
and may require replacement. Over time the converter’s efficiency will  
degrade, due to aging of the internal catalyst. This is characterized by a  
CONV value on the TNx channel of < 0.8 or > 1.2, despite the converter  
being at temperature. The efficiency of the converter should be checked  
quarterly. The converter should be cleaned out on a yearly basis by  
removing the outer tube and shaking the fine dust particles from both the  
outer and inner tubes. This is also a good time to replace the catalyst  
screen, if necessary.  
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 4-2.

4.2 REPLACING THE CATALYTIC CARTRIDGE  
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 M501 NH3, 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 KIT000193.  
7. Re-assemble the converter by doing the above steps in reverse order.

Maintenance Schedule  
Teledyne API Model T201 NH3 Analyzer Operator Manual  
Once you have the right tools and parts, replace the thermocouple as  
follows:  
1. Ensure power is removed from the M501 NH3 Converter. If the  
Converter has been operational you will need to wait for at least 2  
hours for the Converter oven to cool before continuing with the  
replacement of the thermocouple.  
2. Remove the cover from the Converter chassis.  
3. Unscrew the (4) nuts that secure the front panel to the chassis. They  
are located just behind the front panel along the top.  
4. Lower the front panel to gain easier access to the end of the quartz  
tube.  
5. Unscrew the (3) nuts that secure the inner cover protecting the Heater  
Block and quartz tube. Remove this cover.  
6. Cut the tie-wrap hold-down that secures the thermocouple to the  
fitting at the end of the quartz tube.  
7. Loosen the Teflon fitting at the end of the quartz tube taking care not  
to put any stress on the tube, and slide the fitting off the tube.  
8. Remove the thermocouple.  
9. Disconnect the thermocouple wires from the Temperature Controller  
noting that the ‘Yellow’ wire goes to pin 1 and the ‘Red’ wire goes to  
pin 2.  
10. The thermocouple should slide into the Heater Block.  
11. Replace the tie-wrap hold-down.  
12. Form the thermocouple wire so that it rests in the cavity with little  
movement.  
13. Connect the (2) wires of the thermocouple to the Temperature  
Controller. The “yellow” wire should be connected to pin 1 and the  
“red” wire should be connected to pin 2.  
14. At this point, all connections have been made, both electrically and  
pneumatically. A leak check should be performed on the Converter to  
verify that all connections are leak free. If a leak is detected, the leak  
should be resolved before continuing.  
15. Install the inner cover of the Heater Block and secure with the (3)  
nuts. Close the front fanel and secure with the (4) nuts. Install the top  
cover on the Converter chassis.  
16. The Converter is now ready for the application of power. You will be  
looking for an indication from the Temperature Controller that it is  
functioning correctly and driving the heater to the desired “set”  
temperature. Apply power now.  
17. After the Converter comes to the regulated temperature, perform the  
Auto Tune function to tune the Temperature Controller to the new  
thermocouple.

18. After the Auto-Tune process is completed, verify that the “process”  
temperature is indicating that the desired temperature is stable and  
being regulated.  
The converter is now ready for operation.  
4.4 AUTOZERO FLOW CHECK  
Since the T201 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. Remove the top cover of the analyzer. Locate the vacuum manifold at  
the center rear of the chassis. Locate the 1/8” tube fitting located on  
the very left side, as viewed from the rear of the analyzer. It will have a  
label of “0.010” indicating the flow orifice installed.  
3. Remove the fitting and attach a calibrated flowmeter to the block fitting  
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 FL0000001). This filter is meant to protect the orifice; it will  
usually become plugged and need replacement rather than the  
orifice. Replace the filter, and then re-assemble the manifold.  
Restart the sample pump and recheck the flow.

5.0 ALARMS AND CAUTIONS  
Please refer to the T200 Operation Manual for a functional block diagram  
of the analyzer.  
5.1 ALARM  
During initial warm up the internal Zero/Span factory option may exhibit a  
“Block Temperature” warning. This can be cleared once the block  
temperature stabilizes at 50 degrees Celsius. The block temperature is the  
actual temperature of the IZS block manifold inside the M501 NH3  
converter. If the block temperature warning exhibits a negative number such  
as (-37), then the umbilical cord is probably not attached or the Thermistor  
has become disconnected.  
5.2 CAUTION  
Be aware that the ammonia converter operates at 825 degrees Celsius. Do  
not flow highly flammable gases through the T201 analyzer. When the  
analyzer is not in use, it is advisable to turn off the M501 NH3. If the  
converter hasn’t been powered for an extended period of time it is  
recommend that the analyzer be operated overnight prior to use.  
Before spanning the analyzer it is good practice to observe the NORM  
PMT signal. Its value should be equal to twice the concentration of the  
delivered span gas. A common error made during calibration is to span the  
analyzer with either too low a gas concentration or an incorrect value  
entered into the CONC menu for TNx and NOx. Commonly this will  
cause a slope value much greater than one.

6.0 CALCULATING MOLY CONVERTER EFFICIENCIES  
6.1 PURPOSE  
To provide instructions on how to calculate the efficiency of a Moly  
converter when using a GPT method of testing converters, by using the  
US EPA method, where the actual concentration of ozone is not a factor in  
the accuracy of the calculation of the converter efficiency. This procedure  
is based on the Code of Federal Regulations, Title 40, Chapter I,  
subchapter C, Part 50, Appendix F.  
6.2 TOOLS  
API T700 calibrator with O3 Gen option (or equivalent)  
Moly Test Data Sheet (provided on page following this procedure)  
6.3 PARTS  
NONE  
6.4 PROCEDURE  
For the purpose of providing an example, this procedure uses 450 PPB NO  
gas as the reference point, you don’t have to pick these values, they are  
just an example. There is also an assumption that the analyzer has a good  
calibration done @ 450 PPB NO span gas. If this is not the case, then  
once you have finished the leak check on the analyzer, input your 450 PPB  
NO span gas and calibrate the analyzer.  
Note  
For the GPT to be performed correctly, there must be a minimum of  
10% more NO than O3 produced. For example, if the Ozone produced  
is 400 PPB then the NO used must be 440 PPB or more. Typically 450  
PPB NO is titrated against 400 PPB of Ozone.  
1. Leak check machine to ensure that there are no leaks in the analyzer.  
2. For the duration of this test, set the CE factor to 1.0000 (100%) in the  
instrument firmware (this would be in the CAL-CONC-CONV-SET  
menu).

3. The first gas check is to test to see how much the converter is eating  
NO gas or out gassing NO gas. Bypass the converter in the machine,  
by placing a short piece of tubing in place of the converter. Perform a  
straight dilution with NO gas and air as a diluent gas. Input this 450  
PPB NO gas into the analyzer, allow the machine to stabilize, and  
write down the NOx value on your data sheet on line 3.  
4. Remove the converter bypass and install the converter back into the  
NOx sample stream, such that the NO sample goes through the  
converter again and allow the machine to stabilize. Write down your  
NOx value on your data sheet on line 4 AND line 6 of the data sheet.  
5. Note the NO value and input that on line 9 of the data sheet.  
6. Subtract line 3 from line 4 and write that number down on line 5. The  
spec on the data sheet is the value that we use here in house, and  
your spec might be a bit higher. We have found that on NEW Moly  
converters this spec is a good one that predicts a good performing  
Moly converter, but in an older converter might eat a bit more NO, and  
this would be acceptable. If it is a constant value, or changes little  
over time, this is not a problem the machine will calibrate this out.  
7. The next step is to perform your GPT. Generate the same 450 PPB  
NO gas and input 400 PPB of O3 (or generate 450 PPB NO and 400  
PPB NO2, if that’s what your calibrator says). Allow the machine to  
stabilize for 10 minutes and then write down the NOx value on line 7  
and the NO value on line 10.  
8. Subtract line 7 from line 6 and put that onto line 8  
9. Subtract line 10 from line 9 and put that onto line 11  
10. Put the number from line 8 into the letter A on line 12 and put the  
number from line 11 into the letter B on line 12.  
11. Divide A by B and multiply it by 100 and put it into letter C on line 12.  
12. Put the number in letter C onto the C on line 13 and subtract that  
value from 100 and put it into letter D on line 13. this is the converter  
efficiency.  
13. This value should be >96%. If below 96%, replace the converter.
