Ozone detection in the ppb range with work function ...

Thin evaporated films of potassium iodide (KI) are highly sensitive to ozone in work function measurements. Among various other materials KI is well suited for limit detection in the ppb range in normal humid air with work function sensors like SGFET. The cross-sensitivities to other oxidants are comparatively small which is due to a redox system of highly oxidated states on the layer surface ...

Sensitive electrochemical detection of ozone - ScienceDirect

· An amperometric sensor capable of detecting ozone in the low ppb range was developed. The most suitable electrochemical cell was based on a gold-Nafion electrode with M H 2 SO 4 as internal electrolyte solution. It is demonstrated, that by careful selection of the experimental conditions such as electrode materials, electrolyte solution and applied potential the determination of low ...

Ozone - Wikipedia

Ozone's effect on mid-range UV-B rays is illustrated by its effect on UV-B at 290 nm, which has a radiation intensity 350 million times as powerful at the top of the atmosphere as at the surface. Nevertheless, enough of UV-B radiation at similar frequency reaches the ground to cause some sunburn, and these same wavelengths are also among those responsible for the production of vitamin D in …
