ICAD NO2 NOx NO Series 200 High Grade Version

NO2 / NOx / NO Analyser - Series 200 High Grade Version (Model ICAD 200DL)

The ICAD (Iterative CAvity enhanced DOAS) NO2/NOx/NO measurement system uses direct optical absorption spectroscopy in the spectral range between 430 to 465 nm.

In contrast to the ICAD 200 series, the “L” series features an enhanced sensitivity by using a longer absorption cell and increased reflectivity mirrors. By measuring the absorption spectrum and applying the ICAD algorithm, the unique and characteristic absorption structure of NO2 is directly identified and separated from other overlapping absorptions like water vapour (H2O) or Glyoxal (C2H2O2). This gives the advantage of direct NO2 measurements (in comparison to CLD) without interferences to other substances or the need of drying mechanism which introduce new interferences (e.g., CLD, CRD, CAPS).
