Chemiluminescence Analyzers

Definition

Chemiluminescence analyzers are sophisticated devices used to detect and measure light emitted during a chemical reaction, particularly in combustion processes. These analyzers capitalize on the principle that certain chemical reactions can produce light as a byproduct, allowing for real-time monitoring of combustion emissions such as nitrogen oxides (NOx) and other pollutants. Their ability to provide sensitive measurements in-situ makes them valuable for optimizing combustion efficiency and reducing environmental impact.
