What is the primary method for ozone sampling?

The primary method for ozone sampling is chemiluminescence, which is a direct method. This technique involves measuring the light emitted during a chemical reaction that occurs when ozone reacts with a specific chemical reagent. The intensity of the emitted light is proportional to the concentration of ozone present, making it a highly sensitive and accurate method for detecting ozone.

Chemiluminescence is favored for ozone sampling because it provides real-time measurements and can detect low levels of ozone in the air. It is particularly effective in various environmental and industrial settings where monitoring ozone levels is critical for compliance with environmental regulations and for protecting public health.

While other methods may measure ozone levels, they either rely on indirect techniques or have limitations in sensitivity or specificity. Hence, chemiluminescence stands out as the primary and preferred method due to its direct nature and reliability in accurately quantifying ozone concentrations.
