| A Newly Designed Compact Remote TDL Sensing System for Air Pollutants: Field Experiments and Comparison Measurements |
| Fischer, A. (Inst. fur Luft- und Kältetechnik Dresden, Dresden, Germany), R. Herzog, T. Lamp; A. Ropertz (Fachhochschule Düsseldorf, Düsseldorf, Germany), K. Weber. The 92nd Annual Air & Waste Management Meeting & Exhibition, June 1999, St. Louis, MO, 13 pp. |
The remote sensing system for local or diffuse concentrations of gaseous air pollutants developed by the ILK Dresden is a compact and low mass apparatus based on tunable diode laser (TDL) techniques. The prototypes are characterized by compact design and stand-alone and mains-independent operation that allows fast, flexible, and mobile use. The first hardware version works as a one-laser monitor, while the advanced version provides for the simultaneous operation of two lasers; it can measure two gaseous pollutants at the same time. This paper presents results of field measurements of gaseous pollutants—automobile emissions and landfill gases—in the open atmosphere. TDL system and commercial remote sensing systems for air pollutant monitoring (FTIR and DOAS systems) were evaluated in different comparison measurements under real field conditions. The authors review the advantages of the ILK monitoring system and present the status of successful applications. |
