Odor detection value. Odor threshold value (OTV) (also aroma threshold value (ATV), Flavor threshold) is defined as the most minimal concentration of a substance that can be detected by a human nose. Some substances can be detected when their concentration is only few milligrams per 1000 tonnes, which is less than a drop in an Olympic swimming ...

During ozone detection we have the other situation. Gas response to ozone is very fast. Even at 250 C the response time does not exceed 2-3 s. We can assume that during ozone detection inter-agglomerate contacts are gas sensing elements. Only in this case we can explain too fast gas response to ozone. Sn02 films deposited by SILD have macro-porous stmcture, and therefore the influence of …

29/05/2018· Ozone concentration detection methods can be roughly divided into two kinds of instrumental methods and chemical analysis methods. The advantages of the instrument for detecting ozone are high sensitivity, good dependability, and low operator requirements. This is a good method, but since these instruments are usually expensive, they are not easy to use universally.
