INTERAGENCY NITRIC OXIDE MEASUREMENT INVESTIGATION: AEDC RESULTS FOR PHASE I. CALIBRATION TECHNIQUE FOR OPTICAL MEASUREMENT SYSTEM

As part of the continuing investigation to determine the cause of the differences that were formerly found to exist between nitric oxide (NO) concentrations measured with conventional sample extraction-gas analyzer techniques and with an ultraviolet (UV) spectroscopic technique, an experimental program was undertaken at United Technologies Research Center (UTRC) Facility, East Hartford, Connecticut. The purpose of Phase 1 of this program was to measure NO concentrations in several sources with known amounts of NO and over the range of temperatures from 300 to 2,000 K. Spectroscopic and probe measurements were obtained and compared over the test envelope. During this period, a discrepancy in the NO computer model (developed at AEDC) used for reducing the data was identified and has since been corrected. Included in this report are the results of the optical measurements, a comparison of these results with the known concentrations, and a description of the new computer model. (Author)
