The Model 9130T NH3 analyzer measures ambient ammonia in selectable ranges from 0-50 ppb to 0-2,000 ppb using the chemiluminescence principle and an 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 9130T has been designed to overcome the problems of ammonia gas analysis through increased flow, minimum surface area and selected construction materials.
In operation, sample gas is passed through the converter which converts NH3 and other compounds to NO, producing the total oxides of nitrogen (TNX). In the next cycle the sample is routed through a molybdenum converter which converts nitrogen oxides (less NH3) to NO, producing the TN reading. The difference between these readings (TNX – TN – NH3) provides a reading proportional to the NH3 concentration. The analyzer software represents these values in the readout and independent outputs are available for each of these values. The Model 9130T combines the performance advantages of Teledyne’s Model 9110T 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.
