Notes:
A precision ozone calibration system for stratospheric research has been developed and evaluated. Vapor pressures above solid ozone are mixed with a carrier gas (N2) to produce stratospheric ozone mixing ratios at total pressures of 1 to over 20 Torr. The uncertainty in the ozone mixing ratios is approximately ±1.5%, the stability of ozone is ±0.3%. Experiments to be calibrated may sample the gas mixture over a wide range of flow rates; the maximum throughput of gas with corrections of less than 1% to ozone is about 200 Torr l/min. A mass spectrometer system continuously monitors the purity and stability of the N2–O3 gas mixture.
