Chemiluminescence NH3 Analyzer for Ambient Air Quality Monitoring The Model 201E analyzer measures ambient ammonia in selectable ranges from 0-50 ppb to 0-2,000 ppb using the chemiluminescence principle and a Teledyne API designed external ammonia converter and sampling system. Ranges are user selectable in 1 ppb increments and auto ranging is available. Ammonia is difficult to measure accurately because of a tendency to be absorbed into other materials. The “stickiness” of the gas results in slow response times and inaccurate concentration values. The Model 201E has 0-50 ppb to 0-2,000 ppb, user selectable been designed to overcome the problems of ammonia Microprocessor controlled gas analysis through increased flow, minimum surface Multi-tasking software allows viewing of test variables during operation area and selected construction materials. Continuous self checking with warning alarms converter, which converts NH3 and other compounds to In operation, sample gas is passed through the 501NH NO, producing the total oxides of nitrogen (TNX). In the External converter next cycle the sample is routed through a molybdenum Designed to optimize response times converter which converts nitrogen oxides (less NH3) to – Minimal surface area in contact with sample NO, producing the Tn reading. The difference between – low absorption wetted parts – heated zero/span manifold these readings (TNX – TN = NH3) provides a reading proportional to the NH3 concentration. The analyzer software represents these values in the readout, and Continuous Automatic Zero correction Adaptive signal filtering optimizes response time independent outputs are available for each of these values. The Model 201E combines the performance advantages Temperature & pressure compensation Internal data logging with 1 min to 24 hour averages of Teledyne API’s Model 200E NO/NOX analyzer with a converter sampling system designed specifically for this application to produce the most accurate and dependable NH3 measurement system available today.
