Model 9110TH NOx Analyzer Introduction

1. INTRODUCTION, FEATURES AND OPTIONS

1.1. OVERVIEW

The Model 9110T Nitrogen Oxides Analyzer uses chemiluminescence detection, coupled with state-of-the-art microprocessor technology to provide the sensitivity, stability and ease of use needed for ambient or dilution CEM monitoring requirements of nitric oxide (NO), nitrogen dioxide (NO2) and the total nitrogen oxides (NOx). The instrument:

∙Calculates the amount of NO present by measuring the amount of chemiluminescence given off when the sample gas is exposed to ozone (O3).

∙Uses a catalytic-reactive converter to convert any NO2 in the sample gas to NO, which is then measured as above (including the original NO in the sample gas) and reported as NOx.

Since the density of the sample gas effects the brightness of the chemiluminescence reaction, the 9110T software compensates for temperature and pressure changes.

Stability is further enhanced by an Auto-Zero feature which periodically redirects the gas flow through the analyzer so that no chemiluminescence reaction is present in the sample chamber. The analyzer measures this “dark” condition and uses the results as an offset, which is subtracted from the sensor readings recorded while the instrument is measuring NO and NOX. The result gives a sensitive, accurate, and dependable performance under the harshest operating conditions.

The 9110T analyzer’s multi-tasking software gives the ability to track and report a large number of operational parameters in real time. These readings are compared to diagnostic limits kept in the analyzers memory and should any fall outside of those limits the analyzer issues automatic warnings.

Built-in data acquisition capability, using the analyzer's internal memory, allows the logging of multiple parameters including averaged or instantaneous concentration values, calibration data, and operating parameters such as pressure and flow rate. Stored data are easily retrieved through the rear panel serial or Ethernet ports via our APICOM software or from the front panel, allowing operators to perform predictive diagnostics and enhanced data analysis by tracking parameter trends. Multiple averaging periods of one minute to 365 days are available for over a period of one year.
