| Abstract |
A detailed procedural description of a technique for the dynamic calibration of ambient air monitors for ozone, nitric oxide, and nitrogen dioxide is presented. A gas phase titration technique utilizing the rapid gas phase reaction between nitric oxide and ozone is used in such a manner that, with the concentration of one of the three gases known, the concentrations of the other two are determined. Ozone is added to excess nitric oxide in the dynamic calibration system, and a chemiluminescent nitric oxide monitor is used as an indicator of changes in concentration. The decrease observed on the spanned nitric oxide monitor upon addition of ozone is equivalent to the concentration of nitric oxide consumed, the concentration of ozone added and the nitrogen dioxide concentration produced. The advantages of the procedure are that a primary standard for only one of the gases is required and that rapid and routine calibrations of ozone, nitric oxide, and nitrogen dioxide monitors may be performed at a common manifold.
