Teledyne API Model 201A NH3 Analyzer Instruction Manual, 04689, Rev. B1 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.
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.
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.

Teledyne API Model 201A NH3 Analyzer Instruction Manual, 04689, Rev. B1 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.
Teledyne API Model 201A NH3 Analyzer Instruction Manual, 04689, Rev. B1 Table 2.1 - Zero Calibration Procedure - Zero Gas Through the Sample Port Step No. Action Comment 1. Press CAL The M201A enters the calibrate mode from sample mode. Input zero gas through the sample port. 2. Wait 20 min Wait for reading to stabilize at zero value. 3. Press ZERO If you change your mind after pressing ZERO, you can still press EXIT here without zeroing the instrument. 4.
Teledyne API Model 201A NH3 Analyzer Instruction Manual, 04689, Rev. B1 Table 2.3 - Span Calibration Procedure - Span Gas thru Sample Port Step No. Action Comment 1. Press CAL The M201A enters the calibrate mode. Input NO span gas through the sample port. 2. Press Set the converter efficiency parameter to 1.0000, then press ENTR-EXIT. CAL-CONV-SET 2. Wait 20 min Wait for reading to stabilize at span value. 3.
Teledyne API Model 201A NH3 Analyzer Instruction Manual, 04689, Rev. B1 2.1.1 Zero/Span Calibration with Z/S Valves or ECO Option The zero gas enters through the zero gas inlet port on the rear panel. Make sure that the umbilical cord that makes the control connections between the analyzer and the converter is connected (see Figure 2 below). The zero gas valve can be activated by a variety of methods discussed in Section 7 of the M200A manual.
Teledyne API Model 201A NH3 Analyzer Instruction Manual, 04689, Rev. B1 Table 2.5 - Enter the Expected Span Gas Concentrations Procedure Step No. 1. Action Press CALCONCTNX Comment This key sequence causes the M201A to prompt for the expected TNX concentration. Enter the TNX span concentration value by pressing the key under each digit until the expected value is set. This menu can also be entered from CALS or CALZ. 2. Press ENTR ENTR stores the expected TNX span value. 3.
Teledyne API Model 201A NH3 Analyzer Instruction Manual, 04689, Rev. B1 Table 2.6 - CALS - Span Cal Procedure - Gas from rear panel span gas inlet Step No. Action 1. 2. Press CALS Press CAL-CONV-SET Comment The M201A enters the calibrate mode. The Z/S valves are activated to route span gas into the analyzer. Set the converter efficiency parameter to 1.0000, then press ENTR-EXIT. 2. Wait 20 min Wait for the reading to stabilize at span value. 3.
Teledyne API Model 201A NH3 Analyzer Instruction Manual, 04689, Rev. B1 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.
Teledyne API Model 201A NH3 Analyzer Instruction Manual, 04689, Rev. B1 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.
Teledyne API Model 201A NH3 Analyzer Instruction Manual, 04689, Rev. B1 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. Table 3.

B1 Table 3.2 – M501NH Converter Rebuild Parts List Part No. Description KIT000191 Converter Rebuild Kit KIT000139 Ceramic Bushings HE0000007 Ceramic Heater 220W 60 VAC 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.
Teledyne API Model 201A NH3 Analyzer Instruction Manual, 04689, Rev. B1 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.
