| Abstract |
The purpose of the research was to conduct a field study on the merits and limitations of laser coincidence absorption measurement technique applied to long-path monitoring of a gaseous pollutant in an urban atmosphere. Two gaseous pollutants, ethylene and ammonia, were selected and spectral interferences identified. Using a spectrally tunable CO2 laser, measurements and system evaluation were conducted. Selected pollutant concentrations and spectral interference effects were recorded. Concurrent point measurements were made by gas chromatograph for ethylene concentrations. Overall system effectiveness and test results were analyzed and performance evaluated. |
