SUAI scientists have created a device that helps to detect trace amounts of ammonia in the air of industrial premises with high accuracy.
The device created at SUAI will allow monitoring air pollution and can be used to detect trace amounts of ammonia in the air inside of industrial premises and closed technological systems, as well as for rapid leak control of products.
— The principle of operation of the device is based on the conversion of ammonia into aerosol particles and measurement of their concentration. The development provides an increase in the reliability of detection of trace amounts of ammonia in the air, as it reduces the measurement error caused by the presence of impurities such as SO2, NO, NO2 in the atmospheric air. This is due to the use of a differential measurement scheme for microconcentrations of gases in the air in the device, based on a comparison of the analyzed air stream containing ammonia and the air stream purified from ammonia and used as a comparative one,» said Vladimir Timofeev, one of the authors of the project, a master degree student at the Department of Metrological Support of Innovative Technologies and Industrial Safety at SUAI.
