Measuring Ozone in Air
Ozone Characteristics
Many applications require measurement & control of ozone of very low concentrations under 300 ppb (parts per billion). At these low concentrations, one needs to consider the following sampling issues with measuring ozone.
Ozone is highly reactive
-
Ozone is highly reactive. Ozone will react readily with organic materials & surfaces such as walls, flooring, cieling material, plastic test chambers & people. The greater the accuracy of the ozone monitor, the greater the variations will become apparent. If you are testing the accuracy of ozone monitors in test chambers, ensure the devices inside the chamber are clean and do not readily react with ozone. Such materials that work well are fluoropolymers & glass.
-
Ozone will react with dust & oils. Ensure that all surfaces are clean & that any solvents used to clean such surfaces have completely dried. Even slight solvent residuals will have a dramatic effect on the sensor & residual ozone level in the chamber.
-
Ozone concentration gradients are common in rooms & are greatly influence by air movement & eddy currents. This effect will be more pronounced at concentrations less than 100 PPB.
