The reaction between NO and O3 (ozone) emits light. This reaction is the basis for the CLD in which the photons produced are detected by a photo multiplier tube (PMT). The CLD output voltage is proportional to NO concentration.
The light-producing reaction is very rapid so careful sample handling is important in a very rapid response instrument. The Cambustion Fast CLD uses a unique sampling system coupled with miniaturised CLD technology to give millisecond response times.
The Cambustion Fast CLD has two remote sampling heads controlled by a Main Control Unit and is capable of simultaneous sampling in two locations.
