Abstract

Results of dynamic or transient tests and steady state calibration of carbon monoxide and sulfur dioxide continuous air quality monitors are reported. Standard gases and permeation tubes were used to establish low level concentrations bpth for the steady-state calibration and the dynamic testing. The steady-state calibration was in excellent agreement with results obtained from grab samples of the calibration gas stream taken with standard gas bubblers and analyzed by the West and Gaeke procedure. Such tests have been carried out by other investigators with similar results. The important contribution of this paper lies in the application of dynamic testing techniques developed by the senior author and co-workers to determine the transient and frequency response characteristics of these air quality monitors.
