Teledyne manual 1.0 M201E AMMONIA ANALYZER

1.0 M201E AMMONIA ANALYZER

This manual is to be used in conjunction with the M200E NOx Analyzer manual, p/n 04410 supplied with this instrument. It is important that you familiarize yourself with the workings of the NOx analyzer before proceeding with NH3 measurements.

The M201E ammonia analyzer consists of a modified M200E 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 is available in three pneumatic configurations:

∙The M201E with External Calibrator Option (ECO) is shown in Figure 1-1.

∙

The basic system is shown in Figure 1-2.

The M201E with Zero/Span valves is shown in Figure 1-3.

Note: For an M201E 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
