Detection of ozone in a MHz argon plasma bullet jet ...

2012-05-16· The spatially resolved absorption signal of ozone in the jet effluent is determined by the UV-absorption setup presented in figure 8. Here, the commonly used absorption of ozone at the wavelength of nm is taken as a measure for the ozone concentration. A deuterium lamp (DH-2000, Ocean Optics) is used as background source.

NASA - Top Story - SURPRISE! LIGHTNING HAS BIG EFFECT ON ...

Depending on where ozone resides, it can protect or harm life on Earth. Most ozone resides in the stratosphere (a layer of atmosphere between 8 and 25 miles high), where it shields life on Earth from the sun's harmful ultraviolet radiation. At the surface, ozone is a harmful pollutant that causes damage to lung tissue and plants. In the troposphere

The effect of ozone addition on combustion: Kinetics and ...

2019-07-01· With modern technology, ozone can be produced for less than $2/kg . Simek and Clupek ... An ICCD camera connected to a spectrometer served as the detector. Ozone concentration around a plasma jet was then calculated based on the absorption spectrum. In the second method, a quantum cascade laser in the mid-IR region (center frequency 1027 cm −1 = nm) was used as the light source. Ozone ...
