Vue d’ensemble
For the detection of NO an EDL (electrodeless gas discharge lamp) is used. In the EDL, N2 and O2 are converted to NO and produce selective UV radiation. With this radiation a cross sensitivity free NO measurement is made possible. This method is called UV resonance spectroscopy (UVRAS).
Applications
- Analyse portable des gaz (PEMS, Portable Emission Monitoring System)
Characteristics and Benefits
Recalibration
- Readjustment of the zero-point is recommended once a week.
- Contamination of the measuring cuvette can lead to shifting of the end-point. Due to the integrated filter, re-adjustment of the end-point is generally not required – but can be performed once a year.
- Additionally, cartridges filled with an inert and the respective test gas for recalibration of the zero and end-point can be provided.
- Long-term drift is < 1% of Full Scale (F.S.) / 24 h.
