Determination of ozone - NILU

Determination of ozone Introduction. Both chemiluminescence and UV-absorption based methods have been used in the past 20 years for the measurement of ozone in ambient air. After many years of discussion and intercomparison between different wet-chemical methods for calibration of ozone generators used for calibration of the monitors, it is now generally accepted to use UV-photometry as …

How Scientists Measure the Ozone - HowStuffWorks

Both ground stations and planes can use lasers to detect ozone, as well. Advertisement. Other instruments scientists use include instruments on satellites, such as the TOMS (Total Ozone Mapping Spectrometer). The TOMS instrument determines the amount of ozone present in the ozone layer by reading backscattered UV light, which is the UV light the earth emits back into space [source: NASA ...

How to Measure Air Pollutants? | Air Pollution

Now the favoured method for oxidant analysis uses chemiluminescence. The chemiluminescent reaction is that between ozone and ethylene. Chemiluminescence from this reaction occurs over a range of 300-6000 nm, with a maximum at 435 nm. The intensity of emitted light is directly proportional to the level of ozone. Ozone concentrations ranging from ...

Ozone Generators: What They Are, How They Work, and How to ...

· Ozone generators use different methods to generate ozone. Methods to create ozone for purifying purposes include the corona method. The corona method uses an electrical field to turn portions of the oxygen into O3. Ozone is an oxidant, which means it breaks down target materials. Using it on odorous materials will oxidize them and make them less detectable. After this process, ozone …

NASA - Discovering the Ozone Hole: Q&A With Pawan Bhartia

Ozone was a hot topic among scientists an August 1985 meeting in Salzburg, Austria, a few days after Pawan Bhartia presented the first satellite image of the ozone hole. In attendance were Donald Heath, who initiated the ozone measurement program at Goddard in the late 1960s, and the late Sherry Rowland, who later received the Noble Prize for ozone layer research.
