Teledyne API Model 201A NH Analyzer Instruction Manual, 04689, Rev. B1 3 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

Teledyne API Model 201A NH Analyzer Instruction Manual, 04689, Rev. B1 3 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 shortcomin

Teledyne API Model 201A NH Analyzer Instruction Manual, 04689, Rev. B1 3 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 Exter

Teledyne API Model 201A NH Analyzer Instruction Manual, 04689, Rev. B1 3 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

B1 3 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
