Ellis, E. TECHNICAL ASSISTANCE DOCUMENT FOR THE CHEMILUMINESCENCE MEASUREMENT OF NITROGEN DIOXIDE. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/4-75/003 (NTIS PB268456), 1976.
Description:
Gas phase chemiluminescence has been designated as the reference measurement principle for the measurement of nitrogen dioxide (NO2) in the ambient atmosphere. Continuous analyzers based on this measurement principle may be calibrated with NO2 either from the gas phase titration of nitric oxide (NO) with ozone (O3) or from an NO2 permeation device. This document presents pertinent technical information to aid in the understanding of the measurement principle and the prescribed calibration procedures and also includes illustrative examples on how to implement the calibration procedures. The discussion includes recommendations on how to recognize and eliminate potential errors in the individual calibration procedures as well as with the use of NO2 chemiluminescence analyzers. Suggestions on the design and construction of calibration apparatus and procedures for handling and certifying both NO and NO2 calibration standards are included also.
