Abstract
The arsenite method for measurement of NO2 in ambient air was investigated to quantify the effect of sampling flow rate and NO and CO2 concentration on method response. NO and CO2 were previously identified as positive and negative interferents in the method. Flow rates of 220 to 270 cc/min had no effect on the method response; higher flow rates decreased the method response. Atmospheres containing NO2, CO2, and NO were sampled with the arsenite method in a 3x3x3 factorial experiment with five observations per cell. The concentrations were NO2--50, 150, and 250 micrograms/cu m; NO--50, 180, and 310 micrograms/cu m; CO2--200, 350, and 500 ppm.
