Description:
Effects of carbon dioxide (CO2) content of the air on the response of flame photometric sulfur gas analyzers of two types, the Tracor model 270 HA sulfur chromatograph and the Meloy model SA 185 total sulfur analyzer, were studied. These analyzers were used in the Regional Air Monitoring System (RAMS). For each instrument, measurements were made to determine response to a matrix of five CO2 levels and three sulfur dioxide (SO2) levels. Measurements were also made of CO2 concentrations in the influent to and effluent from heatless air dryers providing zero air for calibration at the RAMS stations.
