ozone detection

A highly sensitive fluorescent probe for ozone based on ...

· Ozone is widely used in daily life, but studies have shown that O3 can damage human trachea and lungs, leading to diseases such as asthma, emphysema, and bronchitis. Therefore, it is of great significance to develop a simple and efficient detection method for monitoring O3 in living cells. In this study, 3-(but-3-en-1-yl)-2-(7-(but-3-en-1-yloxy)-2-oxo-2H-chromen-3-yl)benzo[d]thiazol-3-ium …

Ozone Detector Detection Method - Bosean

· 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.
