Improving the Dynamic Response of Continuous Air Pollutant Measurements with a Computer

Performance Characteristics of Instrumental Methods for Monitoring Sulfur Dioxide

“…Yocum, et al 3 reported the effect of HC1 on a continuous SO2 analyzer. Larson, et al 4 listed the response time for two SO2 instruments.…”

A Rapid and Sensitive Colorimetric Reagent for Nitrogen Dioxide in Air

“…1 The article states that for intense though infrequent emissions, accurate measurement of peak concentrations is important. Instrumental response to rapid fluctuations in pollutant level may be limited by the speed of the reactions used for measurement.…”

The Effect of Sample Humidity on the Response Characteristics of SO2and NOxAnalyzer Systems: Aircraft Plume Dispersion Studies

“…(2) A Meloy Labs Model SA 160-2 sulfur gas analyzer, which has a flame photometric detector and a sampling rate of about 200 cc min" 1 . (3) A Monitor Labs Model 8440 nitrogen oxides analyzer, which operates on the chemiluminescence principle and has a sampling rate of about 1000 cc min" 1 .…”
