AIR Pollution Control Is Good Business

Air pollution analyzers, because of inherent lags and response times, will not produce an exact record of pollutant concentrations. A procedure is described for determining the transfer function for an analyzer system. This transfer function is applied to the recorded output to produce a record of the actual atmospheric pollutant concentration at the inlet to the system. This procedure is applied to the carbon monoxide analyzer of the Bay Area Air Pollution Control District monitoring station in San Jose. Results show that variations in peak heights of more than 50% can exist between actual and recorded values.
