AIRYX AIR QUALITY ANALYZERS
Cavity-Enhanced Differential Optical Absorption Spectroscopy (CE-DOAS) is the perfect technology for measuring in situ atmospheric trace gases. 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. 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). As the ICAD system relies not on absolute intensities, but rather characteristic differential absorption structures, it has no absolute zero-point drift and is insensitive to temperature variations, vibrations and light source degradation like other optical instruments. It is thus the perfect tool for accurate and precise long-term measurements, but also for mobile applications requiring a wide measurement range, high precision and fast response times. The operation is simple as no consumable and calibration gases are required (pre-drying of sample air is also not required).
