1.0 M201E AMMONIA ANALYZER This manual is to be used in conjunction with the M200E NO Analyzer x manual, p/n 04410 supplied with this instrument. It is important that you familiarize yourself with the workings of the NO analyzer before proceeding x with NH measurements. 3 The M201E ammonia analyzer consists of a modified M200E nitrogen oxide analyzer and an M501 NH , ammonia converter. The analyzer measures the 3 following individual gas concentrations: TNx (NH and NO ), NO (NO and NO

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 = Me

This process improves zero baseline stability by minimizing the effect of PMT sensor drift. 1.1.2 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

Teledyne API Model M201E NH Analyzer Operator Manual M201E Ammonia Analyzer 3 These rules apply also to your calibrator’s internal plumbing. It is highly recommended that you use a M702SS calibrator in conjunction with the M201E. The calibrator has stainless steel plumbing throughout. The M700 calibrator contains Teflon tubing and internal MFC’s that can be affected by the ammonia gas, therefore, the M700 calibrator is not recommend for use with the M201E analyzer. It is important to k

2.0 CALIBRATION PROCEDURE This section begins with a high-level overview of the calibration procedure for the M201E analyzer. Details are provided starting in Section 2.1: First, take the time to read the M200E 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 (TN, NO , NO). The ammonia and nitrogen x x dioxide concentrations are the
